October 1921 was an incredible month for autumn warmth! The first third of the month saw a phenomenal heat wave which recorded temperatures quite widely into the mid-to upper twenties in the first ten days of the month. In fact, 25C was reached or exceeded on eight of the first ten days of the month. Unsurprisingly, it recorded a very high CET of 12.8C.
October 1921 is also the sunniest October on record too.
Temperatures peaked at 28.9C in London on both the 5th and 6th. These two days held the October temperature record until 1985 and later 2011. London also recorded 27.8C on the 9th during another push of heat. This is the latest date in the year where 80F has been recorded in the UK. Thunderstorms also broke out in the heat in parts of the west.
The heat wave mostly ended on the 11th-12th, when cooler autumnal air moved in from the Atlantic. However another burst of heat arrived around the 18th where parts of the South East recorded 24.4C.
