Overview​

NOTE
The Weather plugin is a paid feature of the OsmAnd app.

The interactive weather map layers in the OsmAnd app allow you to monitor temperature, atmospheric pressure, cloud coverage, wind speed and precipitation in your city or any other location on an interactive global map. The Weather plugin provides hourly weather forecasts for 7 days ahead directly on the OsmAnd map. Weather information can also be downloaded for offline use.

The data source for the Weather plugin is the Global Forecasting System operated by the United States National Weather Service (NWS) and the European Centre for Medium-Range Weather Forecasts (ECMWF).

The precipitation scale is graduated in millimeters (or inches) of water that alls on 1 square meter in 24 hours. 1 mm of rain corresponds to 1 liter of water per 1 square meter.
