WMO03105, Islay, Port Ellen, Scotland
55 40 53N 06 14 59W
Altitude 17 metres
Estimated Class 3, fails Class 2 on 17.6% of 30m – 10m annulus, limit 5%. Perhaps I have been unfair on the perimeter road area but 5% is much smaller.
UHI, local runways otherwise none.
I was surprised at this result after a first glance, devil in the detail. In reality this is coastal, windy so UHI is not likely to normally be significant.
