Switzerland: why suddenly the heat wave

Where is this heat wave? Similarly, We were well sweated at the end of June. However, the organizations were put to the test for ten days when The heat was sufficient In French -speaking Switzerland. Meanwhile, We switzerland: why suddenly heat wave new even feared that it does not last all summer but the time is (fortunately) since cool.

It seems that we used to heat. Nevertheless, “It is 28 degrees these days. Similarly. we do not have the impression that it is very hot, while we are however above the historical average in terms of temperatures,” recalls Mikhaël Schwander, meteorologist in Météosuisse.

Hot in July – Switzerland: why suddenly heat wave

Because the freshness of July is very relative. Similarly, “For the moment. Therefore. we have known temperatures since the switzerland: why suddenly heat wave start of the month slightly superior to seasonal normal, that is to say 1 to 3 degrees up to average depending on the place,” he confides. Therefore, Calculated over a period extending from 1991 to 2020, these average temperatures are located switzerland: why suddenly heat wave new between 25 and 27 degrees in French -speaking Switzerland.

Many, however, feared an prolonged heat wave. Furthermore. “It has never been said that the whole of the summer of 2025 would be scorching,” replies the meteorologist Pierre Eckert. Seasonal forecasts simply highlighted the fact that the average summer temperature “would probably be greater than normal”.

Quiet for the moment

In the short term, Heat waits clearly moved away. “Rather. it should be between 22. 25 degrees next week, with a west current that will bring relatively fresh and wet Atlantic air for switzerland: why suddenly heat wave the season,” says Mikhaël Schwander.

Consequently, the professional hardly fears Smalling temperatures by the end of the month. Because this west current should be maintained. “The models do not indicate switzerland: why suddenly heat wave new any risk of heat wave for the coming weeks. but an alternation of sunny days with periods of precipitation,” he explains.

Health effects

However, planetary warming is there. “We have won nearly 3 degrees in Switzerland compared to the pre -industrial period with global warming. ” recalls the meteorologist Pierre Eckert.

And this switzerland: why suddenly heat wave brings consequences. Between mid-June. early July, scorching conditions were measured for nine days in Geneva and eight days in Neuchâtel, for example. “This is the hottest June since the measures began in switzerland: why suddenly heat wave new 1864,” said Mikhaël Schwander.

These “heat domes” have multiple effects. On health (circulatory problems, heart disease, reduction in mental and physical performance), but also on electrical equipment. Sub -turn of television or washing machines can occur. The Jeanfavre repairer in Lausanne thus noted an increase of 30% of the breakdowns on electrical installations during the. scorching period at the end of June. compared to early July.

Augmented heat wave

Average temperatures greater than normal increase the risk of scorching waves. three days in a row where the maximum heat exceeds 33 degrees. “Global warming creates longer. more intense heat waves. ” recalled recently in switzerland: why suddenly heat wave these Isabelle Fath columns, forecaster in Météosuisse.

And the heat wave may not have said its last word this summer. switzerland: why suddenly heat wave new “The very hot air masses are very reactive with global warming,” said Mikhaël Schwander. Located on North Africa. the latter can easily reach us if the current were to orient itself “in the southwest or south”. Be careful, therefore.

However, this would not necessarily mean a prolonged scorching period. “For a heat wave to be intense. long. special conditions must be put in place, namely a current of the southwest dry and persistent or high-school conditions on Western Europe which block the fresh air of the Atlantic,” he adds. One thing is certain, however: heat peaks have a bright future ahead of them.
