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.
This section covers the mainly French speaking portion of Switzerland. It includes the area around Lake Geneva and the cantons of Fribourg, Geneva, Jura, Neuchâtel, Valais and Vaud.
Some of the weather stations are at high elevations in the Valais (or Pennine) Alps of southwestern Switzerland. Great St. Bernard Pass (Col du Grand St-Bernard) is the highest point on this list at 2472 metres (8110 feet). Also above 1400 metres (or 4600 feet) is the mountain resort town of Zermatt.
