Hot here means 28.7 °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 Amsterdam'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 that never dropped below 20 °C. No multiple is quoted here. Amsterdam recorded 1 in the whole of 1961-1990, so a ratio against that base would be arithmetic rather than evidence. 28 of the 54 cities are gated this way.
Amsterdam's hottest day this year, 36.1 °C, is 2nd on this record. The previous best is 36.4 °C in 2019, the dot on the drop line. A typical summer here peaks at 31.2 °C. Its hot-day count is 7th of 76: a count and a peak are different claims, and neither borrows the other's rank.
