Swiss heatwave set to continue until at least Thursday
According to the Swiss government’s latest natural hazards bulletin, the current heatwave will last on the northern side of the Alps until at least Thursday next week and Friday in the south.
A “slight increase in the humidity of the air mass” is expected to lead to an increase in thunderstorm activity at the weekend. From Sunday, drier, more stable air will flow into Switzerland again, and from Monday, even hotter air.
+ Should Switzerland prepare for a severe drought this summer?
The government forecasts temperatures of 31 to 35 degrees Celcius on the northern side of the Alps – up to 38 degrees in some areas. On the southern side of the Alps, temperatures of 31 to 34 degrees are expected. Minimum temperatures will range between 16 and 23 degrees both north and south of the Alps, though they will be a few degrees higher in urban areas.

Thunderstorms are possible on Friday afternoon and Saturday, particularly in the lake Geneva region, canton Valais, the Bernese Oberland and on the southern side of the Alps.
+ Why Europe is the fastest-warming continent
There is a risk of forest fires throughout Switzerland. In parts of the canton of Graubünden, the risk is classified as moderate. In all other areas, it is significant, high or very high. The latter applies to parts of the cantons of Valais and Graubünden.
The drought poses a high risk across the entire northern side of the Alps. This means that restrictions on water use may be imposed in numerous locations. Many municipalities in Switzerland have already called on residents to conserve water.
According to the government’s natural hazards portal, there is currently a “significant” risk of heat across large parts of the northern side of the Alps, Valais and Ticino. This means there is a significant risk of circulatory problems and physical discomfort.
