Average Precipitation for Switzerland in May





The tables below give monthly averages for rainfall plus snowfall during May at cities, resorts and mountains in Switzerland. Each place has a total for how many days of wet weather it usually gets this month and for the normal amount of precipitation.

The calculation of days only includes the days when precipitation totalled at least one millimetre (0.04 inches).

The month's total precipitation is an average of weather data collected during 1981 to 2010.

You can jump to a separate table for each part of the country: Eastern, Western, Central and Northern Switzerland.
