Rain radar Delémont live
This radar shows the precipitation observed over Delémont (canton of Jura, 471 m) and its surroundings during the last two hours, frame by frame, followed by a 30-minute radar forecast. The map is centred on the municipality: you can see where the rain is coming from and whether it will pass to the north or the south.

How to read this radar over Jura massif
The Jura is the first barrier Atlantic fronts meet: echoes intensify over the ridge and weaken on the south-eastern slope, the Jura foehn effect. Summer storms often form there in the late afternoon and then drift towards the plateau. The radar regularly underestimates precipitation in the deep combes, screened by the relief.

Is the Delémont radar real-time?
A new image is available roughly every 10 minutes. The page loads the image list each time it opens; reload for the most recent one. The last 30 minutes shown are a forecast (nowcasting), not an observation.
Does the radar see snow?
Yes: the radar detects all precipitation. In winter and at altitude, blue echoes are usually snow. The day's rain-snow line is given on the ski resort pages.
Why does the radar show rain when nothing is falling?
The radar beam measures several hundred metres above the ground. In dry air the drops evaporate before reaching it: that is virga. Conversely, in deep valleys the relief screens the beam and the radar underestimates what actually falls.
