When Is It Going To Rain?

Rain forecast in the hour

Météo-France offers updated forecasts for your city every 5 minutes:

  • start and end times of the rainy episode
  • precipitation intensity (low, moderate or high)

These forecasts are produced using data from the Météo-France radar network. The latter make it possible to locate, every five minutes, the zones of precipitation with a precision of the order of the km2. Complex extrapolation techniques calculate their displacement over France during the next hour.

Rain forecasts at 1 hour are available for most municipalities in metropolitan France (77.7% of cities).

However, in some areas, especially near reliefs, the techniques employed are insufficient to provide a quality service. Some cities, especially in the southeast quarter of France, can not benefit from this innovation.
