July weather forecast
Switzerland

July in Switzerland is synonymous with peak summer, with temperatures often reaching their zenith for the year. The Central Plateau, encompassing urban hubs like Zurich and Bern, experiences temperatures generally ranging from 15°C (59°F) to 30°C (86°F). As the warmth intensifies, locals and tourists alike flock to lakes, pools, and other aquatic venues to cool down. The Jura and the Alps, while cooler than the plateau due to their elevation, offer resplendent sunny days ideal for hiking and mountaineering.

In July, the lingering snow on the Jura and the Alps is mostly confined to the very highest altitudes, with vast expanses of meadows and trails becoming accessible. The Central Plateau is bathed in sunshine, and precipitation, which measures between 813mm (32.01") and 1321mm (52.01"), is predominantly in the form of rain. The lengthened days, coupled with the abundant sunlight, ensures that the majority of the day remains luminous, perfect for sightseeing and other outdoor ventures.

Rain showers, though occasionally intense, are interspersed and usually followed by clear skies. Humidity levels in July can approach the higher end, making some days feel muggy, especially in densely populated areas. The periodic Fohn winds might make sporadic appearances, ushering in warm and dry conditions which can amplify the summer heat. With the mountains and valleys presenting a panorama of greenery, juxtaposed against azure lakes, July stands out as a favourite among travellers seeking both adventure and relaxation in the heart of Europe.
