If we refer to the standard established using the average for the years 1983 to 2024, the increase represents between four and seven degrees. Meteonews attributes this increase almost entirely to the heatwave that has been affecting the country for almost two weeks.

In French-speaking Switzerland, the temperature of Lake Geneva has risen to 26 degrees, four degrees warmer than in mid-June and five degrees warmer than the average for the last 41 years.

Lake Neuchâtel followed the same trend, with slightly cooler water (25), but also five degrees warmer than both the second half of June and the 41-year average.

Lake Biel came out on top, with a temperature of 26 degrees, 6 degrees warmer than last month and its average over the last 41 years.

Lugano, the warmest

The highest temperature recorded by Meteonews was in Lake Lugano, at 28 degrees, 5 degrees warmer than the 41-year average.
