June 2020

The Triassic sandstone sea stacks of Ladram Bay on a warm and thundery June day

A rather mixed month with a stand out, record-breaking cold day on the 6th and a near-record hot day on the 24th. Very wet with twice the average rainfall though the majority of this fell in relatively short, heavy thundery downpours. A little warmer and sunnier than normal. Warmest June since 2018 (17.3C), wettest since 2016 (99.7 mm) and the sunniest since 2018 (285.2 hours).
