Weather and climate in Davos (Switzerland)

In Davos, there is a cold mountain climate, with very cold winters, during which the temperature is often below freezing, and cool to mild summers.
The town is located in eastern Switzerland, in the canton of Grisons, at an altitude of 1,550 meters (5,000 feet).
In winter, in periods of high pressure, the sun shines and the temperature exceeds freezing during the day. In periods of bad weather, however, it snows and the temperature remains below freezing even during the day.
During cold spells, the temperature drops to very low values. The coldest record is -30 °C (-22 °F) and was set in February 1956.
In summer, temperatures are mild during the day, and very cool, or even cold, at night. Summer is the rainiest season because of thunderstorms, which usually develop in the afternoon.
Even though the mountain sun increases the feeling of heat, the temperature never reaches very high values. Generally, it reaches 25 °C (77 °F) on the warmest days of the year. However, the temperature reached 30 °C (86 °F) in late June 2019.

Best Time

The best time to visit Davos is the summer, and in particular, the months of July and August, because they are the mildest, although there are often afternoon thunderstorms. Also, since it can get cold at night, it's better to bring a jacket and a sweater even in this period.
Late winter and early spring (February-March) are recommended for a ski holiday, since the days are longer than in December and January.
