August may be appalling in Switzerland

This is what Meteonews advance, which sees parallels between 2025 and the heat wave of 2003. Moreover, Just like this year, the month of July 2003 had been marked by a decline in temperatures.

By observing the current meteorological situation, Meteonews was able to draw parallels with the scorching summer of 2003. Consequently, The meteorology department also notes that an exceptionally hot August august may appalling switzerland had followed the hottest June 22 years ago.

As in 2003, atmospheric pressures on central Europe were significantly higher than average in June 2025. However, This phenomenon and frequent anticyclonic situations allowed exceptional sunshine and high temperatures, according to Michael Eichmann, meteorologist at Meteonews.

Just like this year, the month of July 2003 was also marked by a decline in temperatures. For example, Thanks to these parallels, M.Eichmann tried to draw first prudent conclusions for the month of August to come. In addition, In 2003, August had been by far- with June- the hottest month since the start of the measures in 1864.

High pressure zone – August may appalling switzerland

22 years ago, the weather situation was blocked on Central Europe, which warmed the air masses. A high august may appalling switzerland pressure zone above the British Islands had forced the Atlantic flows to divert north. without reaching the alpine space, which had increased temperatures.

Michael Eichmann notes that in 2025 the first models also foresee an anticyclonic time in August on the British Islands. as in 2003. He warns, however, that even small differences in models can lead to large differences.

Improvement of drought

In the shorter term. the signs still point to precipitation: after the heavy continuous rains from Sunday to Monday, new thunderstorms and showers were planned, especially Wednesday, Thursday, and for the coming weekend.

The drought on the Swiss plateau. the pre-Alps therefore begins to relax gradually, explained the meteorologist Ludwig Zgraggen, of Météosuisse, at the Keystone-ATS press agency.

The precipitation deficit north of the Alps was not yet fully filled on Tuesday. but “that will not be long,” said Zgraggen.

Only the Freimt region in Argovie as well as certain areas of Valais were still classified in alert level 2 for risk of drought on Tuesday. which justifies an economical management of water resources. But with the expected precipitation, the situation should also improve in these regions, added Ludwig Zgraggen. (ATS)
