Hello and welcome to a look back at our weather in August 2021 – We cover the Western Isles and take a look at the rest of the UK’s weather further down in the blog.

August continued the dry trend across the Western Isles. High pressure was the dominating story. We had a couple or wet days. It was a fairly cool month as well.

The highest August temperature was recorded in Scotland according to the Met Office below

It is quite unusual for the highest temperature of August to occur in Scotland, but the suppressed temperatures in the south of England mean that 27.2°C recorded at Tyndrum on 25 August is the highest temperature recorded in the UK during August 2021, and is the lowest such value since August 2010.
