MeteoSwiss Weather Data (SwissMetNet)

Swiss weather station measurements from the Open Government Data (OGD) published by MeteoSwiss, as clean JSON/CSV records. One record per station x timestamp with normalized fields and station metadata (name, canton, coordinates, altitude).

What it does / use cases

• Current conditions and today's 10-minute curve for any of the ~160 automatic SwissMetNet stations (Zurich, Bern, Geneva, Saentis, Lugano, ...).
• Hourly and daily values for the current year (1 January up to yesterday) for analytics, energy/solar/agriculture models, insurance, logistics, dashboards.
• Monitoring: run on a schedule in delta mode and receive only new measurements.

Input

{
  "stations": ["BER", "SMA", "GVE"],
  "granularity": "10min",
  "period": "now",
  "latestOnly": false,
  "mode": "delta",
  "maxResults": 1000
}

Field	Description
stations	Station abbreviations (BER, SMA, GVE, SAE, TAE, LUG, ...). Empty = all stations (one HTTP request per station, ~1 s each, so a full run takes a few minutes).
granularity	10min, hourly or daily.
period	now = since midnight UTC today (10min/hourly); recent = 1 January of the current year up to yesterday. Daily data is only available as recent.
since	Optional ISO date/time (UTC); older records are skipped.
latestOnly	Only the newest record with data per station (current conditions).
mode	all or delta (only new/changed records since the last run with the same input).
maxResults, deltaStateName	Result cap (charged events); optional name for the delta state.

Records are emitted newest first per station. maxResults is a global cap: with many stations and recent data, the first stations fill it, so use since, latestOnly or a station list.

(Illustrative values; coordinates rounded.) Timestamps are UTC and equal the reference_timestamp published by MeteoSwiss. Missing measurements are null. Min/max temperature exist for hourly and daily only. Wind speed/gust are km/h; daily precipitation covers 06:00-06:00 UTC; sunshineMin is minutes of sunshine within the interval.

Pricing

Pay-per-event: you are charged per result (event result, see the Pricing tab for the current price per 1,000 results). Platform usage is included.

Delta mode

With mode: "delta" the actor stores a hash per record id (stationId_timestamp) in a named key-value store of your account. The next run with the same input (or the same deltaStateName) returns only records that are new or changed, so scheduled runs only pay for fresh measurements.

Free plan

Users on the Apify Free plan are limited to 50 results per run. Paid plans have no limit beyond maxResults.
