Rain days per month

By definition, a rain day is a day on which at least 0.1 liters of precipitation per m² fall. This corresponds to a 1 square meter puddle in which the water stands 0.1 mm high — insofar as the water does not seep away or evaporate. So it does not have to rain all day long. January brings the most rainy days (11.0) in France. With an average of only 6.8 days, September is the friendliest. In Saint Barthelemy, it rains most often in December with 15.3 days.

Precipitation amount per day

Depending on the season and the location of a country, the wind brings a varying amount of water with it. As a rule, the water evaporating in the oceans is absorbed and then transported inland. The greatest amount of rain (hail or dew are also forms of precipitation) in France occurs in November, when about 2.5 liters per square meter fall per day. In Saint Barthelemy, the average amount of precipitation ranges from 1.4 liters per day in March to 5.4 in October. However, these are average values. If you consider that there are only 14.0 rainy days in Saint Barthelemy in October, each of them accounts for about 11.5 liters.
