What does Open-Meteo Weather Scraper do?

This actor fetches real-time weather data and forecasts for one or more locations. It uses the Open-Meteo free weather API — one of the most accurate open-source weather services available — and returns structured data including:

• Current conditions: temperature, feels-like temperature, humidity, weather description, precipitation, cloud cover, pressure
• Wind data: speed, direction, gusts in your preferred unit (km/h, mph, m/s, knots)
• UV & daylight: UV index, sunrise/sunset times, sunshine duration
• Daily forecasts: up to 16 days ahead with min/max temperatures, precipitation probability, and weather codes
• Hourly data: optional hour-by-hour breakdown for detailed analysis
• Smart geocoding: accepts city names or latitude/longitude coordinates

Pricing

Open-Meteo Weather Scraper uses a pay-per-event pricing model:

Event	Price
Run started	$0.001
Per location fetched	$0.001

Cost examples:

• 5 locations: $0.001 + (5 × $0.001) = $0.006
• 20 locations: $0.001 + (20 × $0.001) = $0.021
• 100 locations: $0.001 + (100 × $0.001) = $0.101

API usage

Node.js

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_API_TOKEN' });

const run = await client.actor('YOUR_USERNAME/open-meteo-scraper').call({
    locations: ['London', 'Paris', 'Berlin'],
    forecastDays: 7,
    temperatureUnit: 'celsius',
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach(w => {
    console.log(`${w.location}: ${w.temperature}${w.temperatureUnit} - ${w.weatherDescription}`);
});

Python

from apify_client import ApifyClient

client = ApifyClient('YOUR_API_TOKEN')

run = client.actor('YOUR_USERNAME/open-meteo-scraper').call(run_input={
    'locations': ['London', 'Paris', 'Berlin'],
    'forecastDays': 7,
    'temperatureUnit': 'celsius',
})

dataset = client.dataset(run['defaultDatasetId']).list_items().items
for w in dataset:
    print(f"{w['location']}: {w['temperature']}{w['temperatureUnit']} - {w['weatherDescription']}")

Integrations

Connect Open-Meteo Weather Scraper with other tools using Apify integrations:

• Google Sheets — Export weather data to spreadsheets for monitoring and analysis
• Slack / Email — Get weather alerts when conditions change
• Webhooks — Trigger workflows based on weather data updates
• Zapier / Make — Connect to 5,000+ apps for weather-driven automation
• Amazon S3 / Google Cloud — Archive weather data for long-term analysis

Tips and best practices

• City names vs coordinates — city names are geocoded automatically; for precision, use "lat,lon" format
• Forecast days — set to 0 for current weather only; up to 16 days available
• Hourly data — produces detailed output but significantly more data; disable if you only need daily summaries
• Multiple locations — add as many locations as needed; each is fetched in a single API call
• Weather codes — WMO standard codes (0–99) are automatically translated to human-readable descriptions
• Scheduling — set up recurring runs on Apify to build weather history datasets

FAQ

Q: Is an API key needed? A: No. Open-Meteo provides free weather data without authentication for non-commercial use.

Q: How accurate are the forecasts? A: Open-Meteo uses high-resolution models (1–11km) from DWD, NOAA, Météo-France, and other national services. Short-term forecasts (1–3 days) are highly accurate.

Q: Can I get historical weather data? A: This actor focuses on current conditions and forecasts (up to 16 days). Historical data requires the Open-Meteo archive API which may have usage restrictions.

Q: What happens if a location can't be found? A: The actor logs a warning and skips unresolvable locations. Other locations in the same run are still processed.
