37 hot days so far, 2nd of Barcelona's 87 summers.

Its hottest single day, 37.7 °C, is the hottest this station has recorded by this date. A count and a peak are different claims and neither borrows the other's rank.

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 is counted to 8 August, so a part-finished summer is never set against complete ones. 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.

59 nights so far that never dropped below 20 °C, against 11.1 in a typical 1961-1990 summer by this date. That is 3rd of its 87 summers.

The hottest day of Barcelona's summer, to the same date, with 2026 marked. The previous best was 37.0 °C in 2018, the dot on the drop line below it, and a typical summer here peaks at 31.9 °C.
