About

FCST is a weather forecast for air sports, sailing and the mountains. We run our own models: WRF for all of Europe (5.4 km grid, ECMWF input), mountain wave on a 1.8 km grid over southern Poland, ICON-D2 over the Alps, and the Andes in Chile. Pick your disciplines – the home screen shows 0–100 scores, the best time window and a short reason. GLIDING • Thermals: climb rate, cloud base, cloud cover, thunderstorm risk. • Ridge lift from a terrain model and wave at several heights. • Competitions from SoaringSpot: start window, route in AAT areas, conditions on each leg. • Forecast files for XCSoar. VFR FLYING • Weather along the route at your ETA: ceiling, visibility, icing, thunderstorms, wind. • Vertical cross-section of the route, METAR and TAF of airfields on the way. • Suggested route around airspace and an OpenAIP airspace map. IN-FLIGHT MAP • Your glider or airplane on the forecast map, your track and the airspace at your altitude. • Cross-section of the next 20 minutes: real terrain, cloud base, freezing level, rain, thermal top. PARAGLIDING AND PPG • Launch site scores: wind at launch and every 100 m up to the inversion, gradient, turbulence, thermals. • Pilot profile adjusts the wind limits. Launch site database built by pilots. BALLOON AND SKYDIVING • Balloon: launch windows and predicted flight trajectories. • Skydiving: wind at exit altitude and near the ground, jump hours for your drop zone. SAILING • Wind in knots and Beaufort, gusts, squalls, waves and currents. • My voyage: weather along the voyage and the best departure time. SKIING AND HIKING • Ski resorts and ski tours: snow, weather, avalanche danger. • My route: trails and weather at the real elevation of the route. Also: • 12-day weather forecast for any place and rain radar. • Notifications of good and dangerous conditions at your places. • Home screen widgets. • Offline forecast maps – work without signal. • "Who's coming" – see who is heading to the airfield or launch site. • 6 languages: English, Polish, German, Czech, French, Italian. Free: the weather forecast without limits, today's discipline forecasts and warnings. Premium (yearly subscription, 14 days free): the following days, any place, widgets with scores, alerts and offline maps. Forecasts are a planning aid, and the in-flight map is not a navigation device. They do not replace official meteorological information, a briefing or your own assessment of the conditions. Data: WRF (ECMWF), ICON-D2 (DWD), GFS (NOAA), Open-Meteo, Copernicus, OpenAIP, maps © OpenStreetMap.
