Average sunshine duration per month in Berlin until May 2025

* The multi-year average refers to the period from 1961 to 1990, which is an international climatological reference period defined by the World Meteorological Organisation (WMO). According to the source, it is used to assume a uniform database for climatological studies. According to the source, 30-year periods have proven to be favorable for climatological studies, as they ensure, on the one hand, that statistical parameters such as mean values and dispersion can be calculated relatively reliably and, on the other hand, that sufficiently complete measurement series are available.

** No separate data available for December 2024.

Data for the months preceding April 2025 were retrieved from earlier reports of the German Weather Service. 

According to the source: the monthly values mentioned are preliminary values. The data used for the last days of the month are based on forecasts.
