Hot here means 29.9 °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 Hamburg'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.
1 night that never dropped below 20 °C. No multiple is quoted here. Hamburg averages about 0.1 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.
Hamburg's hottest day this year, 39.1 °C, is 2nd on this record. It matches 2022 exactly, the dot on the drop line. A tie is not a record: the rank counts earlier years at or above 2026, so a year that equals it keeps 2026 off first place. A typical summer here peaks at 32.3 °C. Its hot-day count is 9th of 91: a count and a peak are different claims, and neither borrows the other's rank.
