Rain in Colmar: What You Need to Know
The Rhine and Moselle running through or near Colmar defines the rain risk in Rhine valley and Vosges foothills. A hyperlocal radar check shows whether cells are still upstream or already overhead — something a forecast cannot answer.
In Colmar, the gap between 'rain likely this afternoon' and 'rain arriving in 18 minutes' is what a hyperlocal radar fills. The Rhine and Moselle valley often channels cells in ways that make timing unreliable at city level.
The data behind the Colmar rain radar comes from Météo-France — 31 ARAMIS Doppler stations, scans every 5 minutes, processed within seconds. No smoothing, no averages, no delay.

Scans update every 5 minutes and are processed into the ARAMIS mosaic within seconds of each scan cycle — no smoothing, no averaging delay. From Colmar's position on the map, the radar composite shows coverage across the surrounding region continuously, including neighboring departments and cross-border coverage where relevant.
