Switzerland Records One of the Driest Aprils in History.

Large parts of Switzerland experienced one of the driest Aprils on record, according to the MeteoSwiss.

Meteorological data shows that nationwide precipitation reached only 27% of the 1991–2020 average. Experts noted that the number of “wet days” — with more than one millimetre of rainfall — was extremely low and could almost be counted on one hand.

MeteoSwiss confirmed that April 2026 ranks as the fourth driest April since records began in 1864. Particularly, the western and northeastern slopes of the Alps recorded their driest April ever.

Across the country, more than 80 monitoring stations registered record-low precipitation levels. Over 20 locations reported less than 10 millimetres of rainfall, including areas in the Bernese Oberland, Graubünden, and regions between Zofingen and Aarau.

However, meteorologists clarified that low rainfall does not automatically mean drought conditions. Factors such as river and lake water levels, groundwater reserves, soil moisture, and vegetation health also determine whether a drought is occurring.

Since the week beginning April 20, dry conditions have been observed across large parts of the country, raising concerns about potential environmental impacts if the trend continues.
