2 hot days so far, 24th of Tallinn's 47 summers.

Tallinn is compared against 1991-2020, not 1961-1990. This thermometer starts in 1980, so the earlier window every other city uses would cover only its warmer final years here, and a figure against that would look like every other city's while meaning something weaker. 1991-2020 is complete for this station, so it is the one shown. The count and the rank are measured on the full record and stand.

Hot here means 28.1 °C or above, a level about one summer day in twenty used to reach at this station between 1991 and 2020. The percentile thresholds on this page are computed over this period. Where it is not the default 1971-2000, the city's record does not cover that window and a complete later WMO normal is used instead, which yields a HIGHER threshold and so understates rather than overstates. The bar has not moved; the number of days clearing it has. Every year is counted to 31 July, so a part-finished summer is never set against complete ones. That threshold is Tallinn'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.

The 20 °C night is a Mediterranean measure and Tallinn is outside its range. None this year, and one night in the whole of 1961-1990 by this date. No multiple is quoted, because dividing by a base that thin is arithmetic rather than evidence. 24 of the 42 cities are gated this way.

Tallinn's hottest day this year, 28.3 °C, is 31st on this record. The previous best is 34.3 °C in 1994, the dot on the drop line. A typical summer here peaks at 29.2 °C. Its hot-day count is 24th of 47: a count and a peak are different claims, and neither borrows the other's rank.
