Sub-Hourly Historical Weather

This API returns historical weather data from our network stations reporting sub-hourly weather data as well as radar, satellite, and weather re-analyses such as the ERA5. This is historical data at 15 minute intervals, and a request will return data from all data sources within ~15km of the requested point. This API returns sub-hourly (15 minute interval) data.

The following per API request limitations apply (See: pricing):

  • Trial Plan: 1 day per API request.
  • *Plus / Business / Enterprise plans: 5 days of data per API request.
  • Other plan(s): No access

*For convenience, up to 1 month of data can be requested per API request. However, requests that exceed 5 days will count as multiple requests against the plan daily quota. Example: 30 days = 6 requests, 14 days = 3 requests, etc.

All parameters should be supplied to the Weather API as query string parameters.
