Have you got a link p.a.m? Reading maxed at 5.3 so your reading seems right for the coast. It would be interesting for me to see both sources as I'm probably about half way between the two.
I use one of the local private weather stations for the uv. There are number of them but I think most of the others could do with being recalibrate as they (from memory) are often wildly high.
I think this station is very close to the waterline at the coast as it seldom gets frosts, and temps drop rapidly when sea breezes pick up.

Incidently yesterday's 5.5 was the highest so far this year...
More historical uv data can be found for that station in here...
