Hot here means 30.2 °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 Nice'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.
61 nights so far that never dropped below 20 °C, against 18.9 in a typical 1961-1990 summer by this date. That is 2nd of its 77 summers.
Nice's hottest day this year, 33.5 °C, is 22nd on this record. The previous best is 37.7 °C in 2006, the dot on the drop line. A typical summer here peaks at 32.2 °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.
