Hot here means 32.3 °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 Zagreb'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.
19 nights that never dropped below 20 °C, against 6.8 in a typical 1961-1990 summer. That is 28th of its 146 summers.
Zagreb's hottest day this year, 37.6 °C, is 10th on this record. The previous best is 40.3 °C in 1950, the dot on the drop line. A typical summer here peaks at 33.6 °C. Its hot-day count is 3rd of 146: a count and a peak are different claims, and neither borrows the other's rank.
