The most hot days Geneva has recorded by this date.

Hot here means 32.2 °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 Geneva'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.

3 nights so far that never dropped below 20 °C. No multiple is quoted here. Geneva averages about 0.1 a year, and dividing by a base that thin produces a large number and no evidence. 24 of the 42 cities are gated this way.

Geneva's hottest day this year, 37.4 °C, is 5th on this record. The previous best is 39.7 °C in 2015, the dot on the drop line. A typical summer here peaks at 33.3 °C. Its hot-day count is the most on record by this date: a count and a peak are different claims, and neither borrows the other's rank.
