12 hot days in Berlin's 2026 summer, 10th of 79.
Its hottest single day, 39.9 °C, is the hottest this station has recorded. A count and a peak are different claims and neither borrows the other's rank.
Berlin's records begin in 1948, but the station moved 1.25 km in 1970, so they are not one continuous site.

Hot here means 31.4 °C or above, a level about one summer day in twenty used to reach at this station between 1971 and 2000. The bar has not moved; the number of days clearing it has. Every year counted over the whole window; this season is complete, so no year is cut short. That threshold is Berlin's own. It is not a national standard and it is not comparable with another city's: every figure on this page is measured against this station and nothing else.
3 nights that never dropped below 20 °C. No multiple is quoted here. Berlin averages about 1.0 a year, and dividing by a base that thin produces a large number and no evidence. 28 of the 54 cities are gated this way.
The hottest day of Berlin's summer, with 2026 marked. The previous best was 38.5 °C in 2019, the dot on the drop line below it, and a typical summer here peaks at 33.9 °C.
