AUGUST 2020
Unsettled, wet & dull overall. It was the 2nd dullest August on record at nearby Bosullow (records start 2011) after 120.9 hours in 2015. Dry first half (just 5.2mm of rain) very wet 2nd half. The 2nd & 3rd weeks were warm with some very muggy nights.

The really interesting weather was all in the 2nd half of the month, the main points of note:-
18th/19th - Heavy overnight rain.
20th - Brief late evening thunderstorm & torrential rain.
21st – A big sea removed large amounts of sand from several beaches.. F6 westerly in Penzance.
27th - 50.4mm rain 07:00-12:00. Torrential 10:30-11:30. Radar analysis suggested even higher totals in a very narrow band just to the south. Mousehole was closed to all but emergency vehicles for a time. Trains into Penzance were suspended due to flooding on the line.
