If you are interested in historical weather data, please read the "Historical weather data" section.

How to make an API call

API call

https://api.openweathermap.org/data/2.5/onecall?lat={lat}&lon={lon}&exclude={part}&appid={API key}
Parameters
lat, lon required Geographical coordinates (latitude, longitude)
appid required Your unique API key (you can always find it on your account page under the "API key" tab)
exclude optional By using this parameter you can exclude some parts of the weather data from the API response. It should be a comma-delimited list (without spaces).

Available values:

  • current
  • minutely
  • hourly
  • daily
  • alerts
units optional Units of measurement. standard, metric and imperial units are available. If you do not use the units parameter, standard units will be applied by default. Learn more

If you are interested in current weather data, forecasts and weather alerts please read the "Current and forecast weather data" section.

How to make an API call

API call

https://api.openweathermap.org/data/2.5/onecall/timemachine?lat={lat}&lon={lon}&dt={time}&appid={API key}
Parameters
lat, lon required Geographical coordinates (latitude, longitude)
dt required Date from the previous five days (Unix time, UTC time zone), e.g. dt=1586468027
appid required Your unique API key (you can always find it on your account page under the "API key" tab)
only_current optional By using this parameter you can exclude full historical weather data for the specified day, but received the data for only the specified timestamp. If the user specifies this parameter, then the API response will contain only the current section.

To activate this option, please use default value only_current = {true}.
Please find the example of the API call below.
units optional Units of measurement. standard, metric and imperial units are available. If you do not use the units parameter, standard units will be applied by default. Learn more
lang optional You can use the lang parameter to get the output in your language. Learn more

Please note that in order to get historical data for the last five days, you need to make five API calls (one call for each day).

In case you need historical data only for the specified timestamp (not the whole day), we strongly recommend you to use the parameter only_current={true}.

Examples of API call
