Wednesday 27th July Weather forecast for the Western Isles.

Good evening Western isles on this Tuesday evening we are seeing a mixture of sunshine and cloud with some scattered showers mainly confined to Lewis and Harris. Winds under 20 mph and today’s high of 14.7C

I was hoping for more sunshine today across our islands. There was some sunshine but again it was dull in Stornoway where the Met Office site is. So far until today, Stornoway has had just 34 hours of sunshine for the month with just 1.4 hours of sunshine a day on average. Just 26% of the average sunshine for the month after 82% of the month. The graphic I am about to share will hopefully make it clearer.
