Windy.com - Weather Forecast

What Windy.com is for

Windy.com is a weather app built around maps. It shows forecasts as layers you draw over a map of the world, so you can see where rain, wind, waves or a storm system will be, not just a list of temperatures for one town.

The developer names pilots, paragliders, skydivers, kiters, surfers, boaters, fishermen and storm chasers among its users, and says government and rescue teams use it too. It also suits anyone who wants to check whether a weekend will be wet, or follow a tropical storm's path.

Which forecast models it draws on

The app pulls from several weather forecast models at once rather than one provider. The global models it lists are ECMWF, GFS and ICON. For Europe it adds the regional models NEMS, AROME, UKV, ICON EU and ICON-D2.

Outside Europe, the listing names NAM and HRRR for the USA and ACCESS for Australia. Because the models are shown together, you can compare how they agree or disagree for the same place and time.

Radar, satellite, wind and wave layers

Weather radar and satellite imagery are the most direct views of current conditions. Wind is shown as moving flow across the map, and wave height and ocean conditions appear as their own layers for coastal and offshore planning.

The listing describes these as forecasts as well as live views, so the same map can show what is happening now and what the models expect next.

Planning trips, sport and storm tracking

For outdoor sports, the wind and wave layers are the parts most relevant to decisions about a flight, a paraglide, a kite session or a boat trip. For longer trips, you can check the same route across several days of forecast.

For severe weather, the app covers tropical storms and hurricanes, with forecast tracking shown on the map. The developer presents this as a way to follow a storm's expected path rather than a single summary.

Cost and the developer's terms of use

The developer states that Windy.com is free and carries no ads. The listing does not describe any paid tier or unlock, so the features it names are the ones it presents as included.
