The climate in Switzerland widely corresponds to the German weather conditions. It is cold, wet and a few beautiful summer months are also happening. A beach holiday can also be enjoyed in the warmer season, but water temperatures will not reach much more than 19 °C. Due to the warmer temperatures the best time for traveling is from June to September. Winter athletes will find their favorite weather conditions from December to February.

Long-term development of temperatures from 1980 - 2018
In the years 1980 to 2018 there were only 2 weather stations in the whole country, which reported continuous temperature values (Zuerich Fluntern, Lugano). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was Juli 2015 with 24.0 °C. Januar 1985 was the coldest month with an average temperature of -2.5 °C.
The average annual temperature was about 10.3 °C in the years after 1980 and about 12.0 °C in the last years before 2018. So in less than 39 years it has increased by about 1.8 °C. This trend only applies to the selected 2 weather stations in Switzerland. A considerably more comprehensive evaluation of the global warming
has been provided separately.
