WEATHER

What’s going on with Switzerland’s ‘summer’ weather and will it improve?

With frequent rains interlaced with sun, there has not been an uninterrupted stretch of good weather in Switzerland, as you’d normally expect from summer months. But this ‘spell’ is about to be broken.

In terms of weather, the past month has been chaotic: sunny days have been interrupted by bouts of heavy rains, literally dampening the spirits of all those hoping for an uninterrupted stretch of real summer.

Torrential rains have even turned tragic, unleashing flooding and landslides in some parts of Switzerland in June, which claimed several lives and caused substantial material damage.

Since then, the weather has been unstable, alternating between wet and dry spells.

But that is about to change.

‘Lots of sun and higher temperatures’

The mostly cloudy beginning of the week has morphed into a sunny Tuesday in most regions.

Wednesday and the rest of the week is expected to be the same, even though some cloud formations could hang over the Pre-Alps.

“But otherwise, in the plain regions, temperatures will be just within seasonal norms and close to 24 – 26C, and even 26 to 28C in Valais,” MeteoNews weather service indicates.

The forecast for the rest of the week also calls for “lots of sun and higher temperatures,” though occasional, regional thunderstorms can’t be ruled out.

What about the weekend?

On Saturday, temperatures will continue to rise, reaching 30C, and in certain regions even higher.

“In general, Thursday to Saturday will not only be very good weather for swimming, but also the best weather for hiking,” according to Switzerland’s official meteorological service, MeteoSwiss.

Can we expect heatwaves?

Usually, when temperatures in Switzerland reach 30C, and last, uninterrupted, for several days or more, we can speak of a heatwave.

Meteorologists have not given any longer-term forecasts at this time, but if you are hoping to have a long stretch of extreme heat, be careful what you wish for.

Lest you forgot, summers of 2022 and 2023 were extremely hot, making a lot of people very uncomfortable — even more so since air-conditioning in Swiss homes is hard to come by and therefore rare.

The Simplon Pass is closed until further notice.

Outside of Ticino and Valais, the San Bernardino Pass is currently closed due to ongoing roadworks.

These pass closures are in addition to those roads closed in the aftermath of flooding and landslides that hit the country’s southwest at the end of June, making southbound traffic difficult for the time being.

The status of all mountain passes can be checked before travelling at Alpen-pässe, and SRF maintains a constantly updated traffic portal listing road closures and showing traffic jams in real-time.
