Hot here means 32.1 °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 Frankfurt'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.

17 nights that never dropped below 20 °C. No multiple is quoted here. Frankfurt averages about 0.3 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 Frankfurt's 2026 summer. 2026 is the hottest on this record too, at 41.1 °C. Both the count and the peak are records here, which is not true everywhere: a count and a peak are separate claims and each carries its own rank. The previous best was 40.1 °C in 2019, the dot on the drop line, and a typical summer here peaks at 34.3 °C.
