Hot here means 30.6 °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 Barcelona'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.
79 nights that never dropped below 20 °C, against 17.3 in a typical 1961-1990 summer. That is 3rd of its 86 summers.
The hottest day of Barcelona's summer, with 2026 marked. The previous best was 37.4 °C in 2010, the dot on the drop line below it, and a typical summer here peaks at 32.4 °C.
