The numbers behind our brutal summer are now in, and MeteoSuisse says June ran three to four degrees above the 30-year average nationwide.
Geneva, Neuchâtel, Sion and Payerne all posted that gap, and mountain stations at Château-d'Œx and the Grand Saint-Bernard pass showed the same shift.
It was the third-hottest June since records began, and July is on track to match.
Meteorologist Mikhaël Schwander says only an exceptionally cold August could pull the summer average down, which he calls unlikely.
A further heatwave in late July has not been ruled out.
