Hot here means 24.2 °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 counted over the whole window; this season is complete, so no year is cut short. That threshold is Belfast'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 Belfast is outside its range. None this year, and no nights in the whole of 1961-1990. No multiple is quoted, because dividing by a base that thin is arithmetic rather than evidence. 28 of the 54 cities are gated this way.
Belfast's hottest day this year, 28.8 °C, is 8th on this record. The previous best is 30.8 °C in 2022, the dot on the drop line. A typical summer here peaks at 25.0 °C. Its hot-day count is 8th of 96: a count and a peak are different claims, and neither borrows the other's rank.
