How the months are picked.A month qualifies when its average high sits in the comfortable 20–28 °C band (scored down towards 9 °C and 37 °C), rain days are few and sunshine hours are high — at least 78 % of the city's best-scoring month. July and August are then set aside as peak season (school-holiday crowds and prices) whenever at least three other months qualify; where summer is the only comfortable window they stay. Figures are ten-year averages (2016-01-01 to 2025-12-31) from ERA5 reanalysis data via Open-Meteo (CC BY 4.0) for the city centre coordinates.
When to go, and what to expect
Spring (Mar–May)
Excellent — May in particular is one of the finest months to walk the city.
Summer (Jun–Aug)
Great weather but the busiest and priciest window; June is the sweet spot.
Autumn (Sep–Nov)
September is prime; later autumn suits those who want the city to themselves.
Winter (Dec–Feb)
Worth it for markets and museums if you don't mind the chill.

January sees the most rain days at 13, with December, February and July each recording 12. September is among the driest with just 7 rain days.
Is winter worth visiting Berlin?
