Hello and welcome to a look back at our weather in July 2020 – We cover the Western Isles and the rest of the UK at the end.

Temperatures across the island where in the region of 1.5C below the 1981 and 2010 average. As well as between 50 and 30% of the normal sunshine more below.

National Weather stats for July – from the Met Office

According to the Met Office temperatures for the UK where -0.8C below the long term average (1981 – 2010).

Rainfall was above average from parts of England, Wales and Scotland thanks to an active jet stream and successive areas of low pressure. Parts of South West Scotland and North West England had double the July average.

Sunshine was also well below average at 83% with 142.4 hours overall for the UK. In the Western Isles we had very little sunshine and I will get the stats for Stornoway Airport when they are released later in the month.

Shetland where the winners in the UK for sunshine in July. They had above average amounts of sunshine at 136% (172.1) hours of the long term average (1981 – 2010).
