Switzerland is preparing for a significant rise in temperatures this weekend, with forecasts indicating a shift toward summer-like conditions. Following a sunny Thursday with temperatures around 23 degrees, the weather is expected to warm up progressively.
Saturday Set to be Hottest Day of the Year
Meteorologist Peter Wick reports that temperatures will climb to between 25 and 26 degrees on Friday. Saturday is expected to be the peak of the heat, potentially marking the hottest day of the year so far for many regions.
Widespread temperatures of up to 28 degrees are anticipated across much of the country. In certain areas, the 30-degree mark may be breached for the first time.
Regional Heat Distribution and the Bise Factor
According to Wick, temperatures exceeding 30 degrees are “almost certain” in Wallis. Other regions that may come close to this threshold include Basel, Geneva, Ticino, and the Wasserschloss region between Brugg and Aarau.
Whether these areas actually hit 30 degrees depends heavily on the Bise wind. Wick explains that if the Bise blows, it can dampen the temperatures enough to keep them below the 30-degree mark.
Holiday Weekend Outlook
The warmth is expected to persist into Pfingstsonntag (Whit Sunday), with temperatures again forecasted between 27 and 28 degrees. However, the atmosphere in the west may become more unstable due to a “cold air drop” over France.
This meteorological phenomenon could lead to increased cumulus cloud formation and a slight local tendency toward thunderstorms in western regions. By Pfingstmontag (Whit Monday), this influence is expected to disappear, returning the region to mostly sunny high-pressure weather.
Long-Term Forecast
The summer-like trend is likely to continue into the following week, with temperatures expected to remain between 27 and nearly 30 degrees. Meteorologist Peter Wick currently sees no sign of a major weather shift.
While some models suggest the possibility of more variable weather for the weekend after next, We see currently too early for a reliable prognosis.
