Weather forecasts for soaring and free-flight pilots
Cloudbase Predictor helps paragliding, hang-gliding, and sailplane pilots assess flying conditions for a selected location.
It visualises atmospheric forecast soundings from Open-Meteo with thermic forecasts, wind profiles, Stuve diagrams, and cloud-cover charts. You can pick a point on an OpenStreetMap-based map, browse ParaglidingEarth launch sites, save favourite flying sites, choose whether Favorites opens on startup, compare forecast models, and use dark mode in the field.
Forecast data is provided by Open-Meteo. Launch site data is provided by ParaglidingEarth and can be disabled in Settings. Map layers are provided by OpenFreeMap, OpenTopoMap, NASA GIBS, Esri World Imagery, OpenMapTiles, OpenStreetMap contributors, and SRTM.
