Our partner Sensible Weather uses the highest quality weather and climate data available from government modelling centres (typically the source of data used by weather forecast programmes produced by TV, radio and other media). These cover microscale weather phenomena down to the hour.
For European locations (defined by the GPS coordinates of your campsite), its main data source is the official ‘day-of’ forecast by the Global Forecast System (GFS) developed by the United States government National Oceanic and Atmospheric Administration. For other locations, data from other official government modelling centres may be used.
