Traveller notes on Bern in August
Other months in Bern
Switzerland's forum calls July and August the warmest, sunniest months for the lower cities, with some years staying dry and sunny throughout and others bringing rain most days — it varies a lot year to year. Regulars' standard packing list: a t-shirt, a fleece layer, and a proper rain coat, since mountain-influenced weather can change quickly even down in Bern.
