Thermal atlas

Where thermals were found on past flights. It opens on the whole year and the whole day; narrow it down by season, month, part of the day or time slot. Colour shows the mean climb; the overview shows density, cells appear when you zoom in.

Not for use in flight. The thermal atlas is a statistic of past flights; it does not say where thermals will be today and does not replace a weather forecast or in-flight navigation. The pilot decides.

Skyway: a line pilots often follow from thermal to thermal

Region boundary (opens the guide)

Only cells with flights from enough different pilots are shown. Pilot counts are never shown; tap a cell to see its support level (limited, medium, strong).

An empty area does not mean "no thermals"; it means "not enough data".

Wind data: Deutscher Wetterdienst (DWD), ICON-EU, CC BY 4.0; processed with Open-Meteo, derived into wind sectors per flight.
