Weather Forecast API — MET Norway (Yr) hourly and daily forecast for any coordinates

Give it a list of places (latitude and longitude) and get back the official MET Norway Locationforecast 2.0 forecast for each one: hourly steps, daily minimum and maximum temperature, rain, wind, humidity, cloud cover and a plain-English weather summary. Worldwide, no API key, and every place comes with its local time and a ready daily summary that tells you honestly when a day is only partly covered.

MET Norway is the national weather service of Norway; this is the same free data that powers the Yr forecasts. The Actor follows MET Norway's terms of service (identifying User-Agent, coordinates cut to 4 decimals, no request before the Expires time, 429/203 handling) and puts the required credit in every record.

Who it is for

• Developers and data teams who need a clean weather feed for a list of sites without writing and babysitting a client for the MET Norway API.
• Energy, agriculture, construction, events and logistics teams that check tomorrow's rain, wind and temperature for many sites every morning and want them in a spreadsheet (outputMode: "day").
• Anyone building dashboards, alerts or AI agents that need a dependable forecast for coordinates, with units and time zones stated in the data.

What you get

For every place you choose one of three layouts. All of them cost the same (one charge per place) and carry the same place fields, the units and the attribution:

Layout (outputMode)	What a row is	Best for
location (default)	one record per place, with the daily summaries in days and the time steps in steps	APIs, apps, agents
day	one flat row per place and day: min/max temperature, rain, wind, summary	spreadsheets, daily reports
step	one flat row per place and time step: temperature, wind, humidity, rain, symbol	charts, hourly analysis

Anything the source does not give is null. Nothing is guessed, and the weather text for a symbol code the Actor does not know is null instead of an invention.

Real example: one record per place

Run on 19 October 2026, Oslo, forecastDays: 3 (days cut to its first day and steps to its first two entries for this page; the full record has all 3 days and 54 steps, as dayCount and stepCount say):

Real example: a daily row (outputMode: "day")

Tromsø, run on 19 October 2026. The forecast after the first two and a half days is given by the source in 6-hour blocks fixed to UTC hours, so in a zone that is not a multiple of 6 hours from UTC the rain total of a later day can include a block that crosses midnight: precipitationExact is then false (here it is true for 20 October and false from 21 October).

How to use it

Input

1. locations: the places. Each is an object {"name": "Oslo", "latitude": 59.9139, "longitude": 10.7522} (optional altitude in metres and timeZone such as Europe/Oslo) or the text "latitude, longitude" or "Name: latitude, longitude". A dot is the decimal separator. Up to 10,000 places per run; repeated places are merged and charged once.
2. forecastDays: 1 to 10 local calendar days, today included. Default 3. MET Norway forecasts about 9 to 10 days ahead, so asking for 10 can return 9 or 10.
3. outputMode: location, day or step, as above.
4. timeStep: hourly (every step the source gives: 1 hour apart for roughly the first 2.5 days, then 6 hours apart, each step says its stepHours) or six-hourly (only 00, 06, 12 and 18 UTC, each with the 6-hour rain, minimum and maximum).
5. units: metric (°C, km/h, mm, hPa), imperial (°F, mph, inches, inHg) or source (as MET Norway delivers: °C, m/s, mm, hPa). The unit of every value is written in the row's units.
6. includeDaily and includeSteps: with the location layout, leave out days or steps (they become null). Switching includeSteps off makes records about 10 times smaller.
7. includeExtendedFields: adds feels-like temperature, dew point, low/medium/high cloud cover, fog and the clear-sky UV index. MET Norway gives them for part of the horizon (fog and UV for the first days), otherwise they stay null.
8. useCache: on by default. See "Be kind to the source" below.

Output

A location record has the same 24 fields in every run, a day row the same 32 fields, a step row the same 42 fields; the key order is fixed. The place and source fields, in every layout:

Field	Type	What it is
id	string	Stable key of the place: the coordinates as sent to the source (4 decimals), plus "@altitude" when you gave an altitude. Use it as the key when you join runs or modes. Repeated in every row of a place.
name	string / null	The name you gave the place, cleaned of line breaks. Null when you gave none. The Actor never looks names up.
latitude	number	Latitude used for the forecast, in decimal degrees, cut (not rounded) to 4 decimals as MET Norway requires.
longitude	number	Longitude used for the forecast, in decimal degrees, cut (not rounded) to 4 decimals as MET Norway requires.
coordinatesTruncated	boolean	True when you gave more than 4 decimals and they were cut to 4 (about 11 m). The forecast is for the cut point.
elevationMeters	number / null	Ground elevation the forecast was computed for: your altitude if you gave one, else the height MET Norway's own terrain model uses for that point. Null if the source does not say.
elevationSource	string / null	"input" when it is the altitude you gave, "source-model" when MET Norway chose it, null when unknown.
timeZone	string / null	IANA time zone of the place (Europe/Oslo): the one you gave, else looked up offline from the coordinates. Null when none could be found: then days are UTC days and local times are null.
timeZoneSource	string / null	"input" (you gave it), "tz-lookup" (offline lookup from the coordinates: approximate within a few km of a zone border), or null.
dayBasis	string	"local" when days follow the place's local calendar day, "utc" when no time zone is known.
status	string	"ok" = the forecast was read and is in this record; "error" = it could not be read (see error). Error records are free.
error	string / null	Why the forecast could not be read, in plain words. Null when status is "ok".
notice	string / null	Something the source said that you should know, for example that MET Norway marks the product deprecated (HTTP 203). Null normally.
forecastUpdatedAt	string / null	When MET Norway last updated the model run behind this forecast (meta.updated_at), ISO 8601 UTC.
expiresAt	string / null	The source's Expires time: a newer forecast is not available before it. ISO 8601 UTC.
fetchedAt	string / null	When this Actor last asked MET Norway for this place (it can be earlier than the run when the stored answer was still valid).
dataSource	string / null	"network" = read from MET Norway in this run; "cache" = a stored answer that had not expired yet (no request was made); "revalidated" = asked with If-Modified-Since and the source said nothing changed.
units	object	The unit of every measured value in this row, so a row can be read on its own. Keys: temperature, windSpeed, precipitation, pressure, humidity, cloudCover, fogFraction, windDirection, uvIndexClearSky.
sourceUrl	string / null	The exact MET Norway request this forecast comes from (public, no key).
attribution	string	The credit CC BY 4.0 requires. Keep it when you publish or redistribute the data.

Extra fields of the location layout:

Field	Type	What it is
stepCount	number / null	Number of entries in steps. Null when steps is null (includeSteps off) or the place failed.
dayCount	number / null	Number of entries in days. Null when days is null (includeDaily off) or the place failed.
days	array / null	Daily summaries, one object per day with the fields of the daily rows (date, weekday, partial, hoursCovered, precipitationExact, temperatureMin, temperatureMax, precipitationTotal, windSpeedMax, uvIndexClearSkyMax, symbol, summary). Null when includeDaily is off or the place failed.
steps	array / null	Forecast steps, one object per time step with the fields of the step rows (time, localTime, localDate, stepHours, temperature, ...). Null when includeSteps is off or the place failed.

Fields of a day row, and of each entry of days:

Field	Type	What it is
date	string / null	The calendar day (YYYY-MM-DD) in the place's time zone, or in UTC when dayBasis is "utc". Null in an error row.
weekday	string / null	Mon, Tue, Wed, Thu, Fri, Sat or Sun.
partial	boolean / null	True when the forecast covers less than a full day: the first day starts at the current hour, the last day may be cut by the end of the source's horizon. Extremes and totals then cover only the covered hours.
hoursCovered	number / null	Hours of this day that have a forecast value for precipitation (24 for a whole day, 23 or 25 on a daylight-saving change).
precipitationExact	boolean / null	True when every forecast block behind precipitationTotal lies inside this day. After about 2.5 days MET Norway only gives 6-hour blocks fixed to UTC hours (00, 06, 12, 18); in a zone that is not a multiple of 6 hours from UTC a block can cross local midnight. It is then counted in the day it starts in, never split, and this is false.
temperatureMin	number / null	Day rows: lowest of the forecast temperatures at the steps of the day and of the 6-hour minimums that lie inside the day. Step rows: the 6-hour minimum for 6-hour steps, null for 1-hour steps.
temperatureMax	number / null	Day rows: highest of the forecast temperatures at the steps of the day and of the 6-hour maximums that lie inside the day. Step rows: the 6-hour maximum for 6-hour steps, null for 1-hour steps.
precipitationTotal	number / null	Sum of the forecast precipitation of the blocks that start in this day (rain, melted snow). Null when the source gave none for the day.
windSpeedMax	number / null	Highest forecast wind speed (10 m, mean wind, not gusts) at the steps of the day. After the first 2.5 days steps are 6 hours apart, so a short peak can be missed.
uvIndexClearSkyMax	number / null	Highest clear-sky UV index at the steps of the day. Only with includeExtendedFields; null otherwise or when the source has none (night).
symbol	string / null	MET Norway weather symbol code for the step, for example "clearsky_day" or "lightrain". Day rows: the most frequent symbol of the day without the _day/_night suffix, ties go to the worse weather.
summary	string / null	English text of the symbol ("Clear sky", "Light rain showers and thunder"). Null for a code this Actor does not know: the code is never guessed.

Fields of a step row, and of each entry of steps:

Field	Type	What it is
time	string / null	Start of the step, ISO 8601 UTC, exactly as the source gives it. Null in an error row.
localTime	string / null	The same instant in the place's time zone with its UTC offset, for example 2026-10-19T14:00:00+02:00. Null when no time zone is known.
localDate	string / null	Calendar day of the step in the place's time zone (matches date in the daily rows). Null when no time zone is known.
stepHours	number / null	How many hours the precipitation and symbol of the step cover: 1 for the first 2.5 days or so, then 6. Null for the very last step, which only carries instant values.
temperature	number / null	Air temperature at 2 m at the start of the step.
temperatureMin	number / null	Day rows: lowest of the forecast temperatures at the steps of the day and of the 6-hour minimums that lie inside the day. Step rows: the 6-hour minimum for 6-hour steps, null for 1-hour steps.
temperatureMax	number / null	Day rows: highest of the forecast temperatures at the steps of the day and of the 6-hour maximums that lie inside the day. Step rows: the 6-hour maximum for 6-hour steps, null for 1-hour steps.
apparentTemperature	number / null	Feels-like temperature, as computed by MET Norway. Only with includeExtendedFields.
dewPoint	number / null	Dew point temperature. Only with includeExtendedFields.
humidity	number / null	Relative humidity at 2 m, percent.
pressure	number / null	Air pressure at sea level.
cloudCover	number / null	Total cloud cover, percent of the sky.
cloudCoverLow	number / null	Low-level cloud cover, percent. Only with includeExtendedFields.
cloudCoverMedium	number / null	Mid-level cloud cover, percent. Only with includeExtendedFields.
cloudCoverHigh	number / null	High-level cloud cover, percent. Only with includeExtendedFields.
fogFraction	number / null	Fog area fraction, percent. Only with includeExtendedFields; MET Norway gives it for the first days only.
windSpeed	number / null	Mean wind speed at 10 m (gusts are not in this product).
windDirection	number / null	Direction the wind blows FROM, in degrees: 0 = north, 90 = east, 180 = south, 270 = west.
uvIndexClearSky	number / null	UV index for a cloudless sky (real UV is lower under cloud). Only with includeExtendedFields; null at night and beyond the first days.
precipitation	number / null	Precipitation (rain, melted snow) over the step, in the unit of units.precipitation, for stepHours hours. Null for the last step.
symbol	string / null	MET Norway weather symbol code for the step, for example "clearsky_day" or "lightrain". Day rows: the most frequent symbol of the day without the _day/_night suffix, ties go to the worse weather.
summary	string / null	English text of the symbol ("Clear sky", "Light rain showers and thunder"). Null for a code this Actor does not know: the code is never guessed.

Also stored: a SUMMARY record in the key-value store with the settings used, the totals, the number of requests, cache hits, retries, the places that failed and why, the places not read if the run stopped, and the attribution.

How the daily numbers are worked out

• A day is a local calendar day of the place (midnight to midnight in its time zone), or a UTC day when no time zone is known (dayBasis).
• temperatureMin / temperatureMax: lowest and highest of the forecast temperatures at the steps of the day, together with the 6-hour minimum and maximum the source gives for each 6-hour block that lies entirely inside the day.
• precipitationTotal: the sum of the source's precipitation blocks that start in the day (1-hour blocks first, 6-hour blocks later). A block is never split. When a 6-hour block crosses local midnight, precipitationExact is false.
• windSpeedMax: the highest forecast mean wind at the day's steps. Gusts are not part of this product, and after the first 2.5 days steps are 6 hours apart, so a short peak can be missed.
• symbol / summary: the most frequent weather symbol of the day, weighted by hours, day and night variants merged; if two are equally frequent the worse weather wins.
• partial, hoursCovered: the first day starts at the current hour and the last day may be cut by the source's horizon, so a day can cover less than 24 hours. hoursCovered counts the hours of that day with a precipitation value (23 or 25 on a daylight-saving change). Never compare a partial day's minimum with a full day's without looking at it.
• Time zone: from the timeZone you give, else looked up offline from the coordinates with the CC0 tz-lookup polygon table, then the real UTC offset (including daylight saving) from Node's time zone database. Near a zone border (a few km) the lookup can pick the neighbour: give timeZone for places where this matters. Open-sea points get a nautical zone such as Etc/GMT+2. If no zone is found, days are UTC days, local times are null and notice says so.
• Units are converted from the source's °C, m/s, mm and hPa: °F = °C × 9/5 + 32, km/h = m/s × 3.6, mph = m/s × 2.2369, inches = mm / 25.4, inHg = hPa × 0.02953.

How much does it cost?

One event, forecast: $0.0008 per place whose forecast is delivered ($0.80 per 1,000 places). Platform usage is included. You are charged once per place whatever the layout, the number of days or the rows it produces, and also when the answer came from the stored copy (you pay for the forecast delivered, not for the request).

Free: places that fail, invalid or repeated entries in your list, anything not read because the run stopped. The Actor stops by itself when your maximum cost per run is reached ("budget exhausted" in the SUMMARY) and never goes one place over.

Use	Forecasts	Cost
50 sites, once a day, for a month	1,500	$1.20
200 sites, every 6 hours, for a month	24,000	$19.20
5,000 grid points, once	5,000	$4.00

Speed: about 3 places per second (one request every 0.3 seconds, on purpose), so 1,000 places take about 5 to 6 minutes on the default 256 MB.

Be kind to the source (and keep the cost of reruns low)

MET Norway is a free public service. It asks clients not to repeat a request before the Expires time of the previous answer, and to use If-Modified-Since. With useCache on (default), each answer is kept in a key-value store named met-norway-forecast-cache in your account (compressed, about 7 KB per place, up to 5,000 places): a place whose stored answer has not expired is served from it with no request (dataSource: "cache"); an expired one is asked again with If-Modified-Since and a "not modified" answer ("revalidated") just extends it. MET Norway sets Expires only some minutes ahead (we saw about 17), so the stored copy mostly helps reruns within minutes: retries, the same list in another layout, overlapping lists. Delete the store whenever you like.

Limits to know

• Coordinates only. Place names are not looked up. Free geocoding services either limit commercial use to paid keys (Open-Meteo's geocoding) or ask for no bulk use and at most 1 request a second (OpenStreetMap's Nominatim), so the Actor does not guess which "Springfield" you meant. Put the name you want back in name.
• Forecast, not observation. No history, no measured data, no weather warnings, no sunrise or sunset, no probability of precipitation, no gusts.
• Model point. The forecast is for the point at the terrain height of MET Norway's model unless you give altitude. In mountains, give it.
• Horizon about 9 to 10 days; the long range is 6-hourly and less certain. Not for safety-critical decisions.
• Up to 10,000 places a run, 4 attempts per place, each request cut at 30 seconds, answers over 8 MB refused. If the source answers 429 (too many requests) three times in a row, the run stops by itself and lists the places not read.

FAQ

Is this allowed? Is the data free to use commercially? MET Norway licenses its data under CC BY 4.0 and the Norwegian Licence for Open Government Data (NLOD) 2.0 (https://api.met.no/doc/License). Credit is required: it is in the attribution field of every row. Keep it if you publish or pass on the data. The terms of service (https://api.met.no/doc/TermsOfService) require an identifying User-Agent, coordinates with at most 4 decimals, respect for Expires, and a rate under 20 requests a second for an application: this Actor sends weather-forecast-met-norway/<version> (+https://github.com/FarGitub003), cuts coordinates (coordinatesTruncated), uses one request at a time with 0.3 s between, and logs a 203 ("product deprecated") as a warning and in notice.

Why is the first day "partial"? It starts at the current hour, and its numbers cover only the hours left. hoursCovered and partial tell you.

Why are some precipitationExact false? See above: the source's later 6-hour blocks are tied to UTC hours.

Can I give a city name? No, see "Limits". Use a geocoder you have a licence for, and pass the coordinates and the name.

Which time zone do you use for my place? The one in the row (timeZone, timeZoneSource).

Do you keep my places? Only the answers in your own met-norway-forecast-cache store, keyed by the coordinates. Nothing is sent anywhere but to api.met.no.

Use it from code

Replace YOUR_TOKEN. The Actor is called far003/weather-forecast-met-norway.

JavaScript

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_TOKEN' });
const run = await client.actor('far003/weather-forecast-met-norway').call({
    locations: [
        { name: 'Oslo', latitude: 59.9139, longitude: 10.7522 },
        'Milan: 45.4642, 9.19',
    ],
    outputMode: 'day',
    forecastDays: 5,
    units: 'metric',
});
const { items } = await client.dataset(run.defaultDatasetId).listItems();
for (const day of items) console.log(day.name, day.date, day.temperatureMin, day.temperatureMax, day.precipitationTotal, day.summary);

Python

from apify_client import ApifyClient

client = ApifyClient("YOUR_TOKEN")
run = client.actor("far003/weather-forecast-met-norway").call(run_input={
    "locations": [
        {"name": "Oslo", "latitude": 59.9139, "longitude": 10.7522},
        "Milan: 45.4642, 9.19",
    ],
    "outputMode": "day",
    "forecastDays": 5,
    "units": "metric",
})
for day in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(day["name"], day["date"], day["temperatureMin"], day["temperatureMax"], day["precipitationTotal"], day["summary"])

Schedule. In Apify, add a Schedule for the Actor (for example every morning) and a webhook or integration (Slack, e-mail, Make, Zapier, Google Sheets) on Run succeeded. In day layout the dataset opens as a table, ready for a spreadsheet export.
