Weather & Environmental Data by Location

Pay per usage
Returns current conditions, daily weather, air quality and nearby earthquakes for place names or coordinates, joining Open-Meteo forecast and air-quality data with the USGS earthquake catalog on one location and date axis.
One entry per location. Accepted formats: (1) a place name such as 'Shanghai', 'Berlin, Germany' or 'San Francisco' (the top geocoding result is used); (2) decimal coordinates such as '31.23,121.47'; (3) labeled coordinates such as 'lat:31.23,lon:121.47'.
[ "Shanghai", "Berlin", "San Francisco"]Number of forecast days to return per location, including today (1 to 16). Combined with Past Days this sets the daily record window.
Number of past days to include before today (0 to 30), using the same forecast model run. Set to 0 for forecast-only output.
When enabled, hourly Open-Meteo air-quality data (PM2.5, PM10, US and European AQI, ozone, nitrogen dioxide) is aggregated into daily mean and maximum fields on each daily record.
When enabled, the USGS earthquake catalog is searched around each location and returned as earthquake records; each daily record also gains the count and strongest magnitude of returned events on that date.
Radius around each location for the USGS earthquake search, in kilometers (10 to 2000). Larger radii return more events in seismically active regions.
Minimum magnitude for returned USGS events (0 to 10). The default 2.5 keeps locally noticeable events and filters micro-earthquakes.
Maximum USGS events returned per location (0 to 200), strongest first. Daily earthquake counts are computed over the returned events, so a low cap can undercount very active dates.
Optional Open-Meteo subscription key. When supplied, your key is used on the commercial customer endpoints for geocoding, forecast and air quality. When left empty, the operator's configured Open-Meteo key is used instead, so runs are covered commercially by default.
