Swiss climate is characterised by a number of regularly occurring weather patterns and other routinely occurring phenomena: They range from snowfall during spring, a cold snap in June to fog and Indian summer in autumn. The weather service MeteoSchweiz is analysing these events and putting them into longer-term climatological context.
Reports throughout the year
A regularly occurring weather pattern is defined as a deviation from the average annual course of meteorological elements that occurs at specific times with reasonable regularity. Singularity is another term used to describe this phenomenon.
