How it works

Score points: +2 wind direction in optimal window · +1 acceptable direction · +2 wind speed in sweet spot · +1 flyable speed · +1 no low stratus (thermals only) · +1 CAPE/BLH bonus (thermals only) · +1 dry soil on cool days (thermals — Bowen ratio)

Ridge and ground handling sites use civil twilight to determine the flyable period. Each hour is checked individually; consecutive flyable hours form windows. Tap or hover cells for details and all windows.

Ground handling: wind ≥3 m/s, gusts ≤9 m/s, no precipitation. Stroomi requires NW (280°–320°), Kakumäe requires S–N via W (180°–360°), Harku any direction.
