Heat Nottingham · Nottingham Watnall · the 2026 summer, complete

20 hot days in Nottingham's 2026 summer, 2nd of 69.

Correction

Until today this page called 2026 the most hot days Nottingham has recorded by this date. It was never true. 1995 cleared the same bar on more days, and we had set 1995 aside as too incomplete to rank.

That exclusion was the mistake. A year with gaps in it can only count too few days, never too many, so its total is a floor rather than an estimate. A floor above ours is not a year we cannot compare with. It is a year that beat us. The filter meant to protect the comparison removed the one year capable of disproving it.

No temperature changed and the bar did not move. What was wrong was our rule about which years were allowed to argue.

Hot here means 27.9 °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 Nottingham'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.

1 night that never dropped below 20 °C. No multiple is quoted here. Nottingham did not record a single one in the whole of 1961-1990, so there is no base to divide by. 28 of the 54 cities are gated this way.

Nottingham's hottest day this year, 36.9 °C, is 2nd on this record. The previous best is 39.8 °C in 2022, the dot on the drop line. A typical summer here peaks at 29.4 °C. Its hot-day count is 2nd of 69: a count and a peak are different claims, and neither borrows the other's rank.
