The climate of Lausanne
The city of Lausanne is situated in Switzerland and is characterized predominantly by a Marine west coast climate with warm summers, as per the Köppen climate classification, labeled as Cfb. This categorization is born from the yearly weather patterns of predictable rainfall and relatively mild temperatures, both of which are typical for this climate zone.
Throughout the year, rainfall in Lausanne is a common occurrence. Monthly, the rainfall millimeters range from a minimum of 48mm in April to a maximum of 103mm in December. A closer look at the number of rainfall days reveals an interesting pattern. While one might expect the months with the most rainfall millimeters also to possess the maximum number of rainfall days, this is not necessarily the case. April has the least amount of rainfall millimeters but is not the month with the fewest days of rain. This honor is shared between February with 11.8 days and September with 12.5 days. The month with the heaviest rainfall, December, also possesses a relatively high number of rainfall days at 13.8. Therefore, it seems that while rainfall in Lausanne can be expected throughout the year, some months may have heavy showers spread over a shorter period, rather than light showers spread over many days.
When it comes to temperature, the patterns are relatively consistent with the standard understanding of seasonal changes. The peak temperatures manifest during the summer months, with a high of 22.2°C in July and a low only slight less at 12.6°C. Conversely, during the winter months the city experiences lower temperatures. January and February both record the same low temperature reading of -2.2°C, while the high swings between 3.3°C and 3.8°C in those months.
An exciting factor in Lausanne’s weather profile is the snowfall. Here, a strong correlation emerges between the rainfall and snowfall patterns - when one increases, the other decreases. The influence of this inverse relationship results in higher snowfall during the winter months, peaking in February with 173mm and December close behind with 184mm. Snowfall days sees its zenith in January and December with 10.3 and 8 days respectively. However, the snow is virtually non-existent from May to September.
