Many people are surprised to discover that the Western Isles has amongst the highest total hours of sunshine in the UK, with some areas recording more than 1400 hours per year. 

This is in part due to the fact that during the summer months the daylight hours are much greater (up to six hours more than London), but even allowing for this the sun shines for between 40 and 50% of the summer months. 

For example, in Oban the average recorded values are seven hours per day for May, and six for both June and July.  The values for Tiree and other islands are even higher than this.
