Overall very warm, 2nd warmest month on record after 19.4C in August 1995. Also sunny (based on Camborne) & dry. It was the 10th consecutive dry month. 

There was an unprecendented hot spell. On the 11th my all time temperature record fell despite a generally onshore wind. It reached 29.8C,  beating the previous record of 29.6C on 17th July 2006.  It was >30C in much of Cornwall, hotter here in 'Penwith' than in the July 2022 heatwave. John Chappell's site near Land's End reached 32.0C @  14:24 a new record despite a F3-4 breeze.

 On the 14th August there was no sea breeze whatsoever in Penzance. A very light onshore SE wind was replaced by a F1-2 WNW around noon, but this was then killed by the sea breeze effect. The temperature was around 28C at noon, jumping quite quickly to 30C by 12:45 peaking at 30.3C at 15:30.

 Up until this year I had only ever (since 1991) recorded >28C on 10 occasions. The 11th occasion came in July this year, just the 1 day. The 14th August was the 5th consecutive day >28C and 2 of those broke the previous temperature record.

The 15th August saw a minimum of 19.7C, my warmest night on record beating 19.6C on 5th August 2003.

Warmest August in my record starting 1983 here at Warlingham.  Mean max 26.3, mean min 14.2, overall 20.2°C.  This is 0.5 degC warmer than 1995, which is saying something.  Rainfall 35.8 mm of which 22.7 mm fell on one day, nominally the 24th though most of it fell after about 3 a.m. on the 25th.  Lowest max 21.3°C so no cool days.
