History & Climate Data

note

For further information, please consider the weather variable documentation.

Historical Data Packages

The historical data of meteoblue is built up through archiving the raw weather model output once a day (forecast hours 12 till 36). Generally, the delivered data is from the model with the highest resolution for the given location and time.

The data packages deliver time series of historical weather data of maximum one year per call. You can set a start and end date (YYYY-MM-DD). If the time range between start and end date is bigger than one year, the API will check the end date only and deliver data for 366 days backwards.

Example:

  • &startdate=2000-01-01&enddate=2015-12-31: You will get data from 2014-12-31 until 2015-12-31
  • &startdate=2015-01-01&enddate=2015-01-31: You will get data from 2015-01-01 until 2015-01-31
