Hot here means 33.9 °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 Bordeaux'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.

31 nights that never dropped below 20 °C, against 1.1 in a typical 1961-1990 summer. That is 1st of its 77 summers.

The hottest day of Bordeaux's 2026 summer. 2026 is the hottest on this record too, at 42.5 °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 41.6 °C in 2025, the dot on the drop line, and a typical summer here peaks at 35.7 °C.
