Dewpoint 16.5C, air temperature currently 19.8C following a few bursts
of sunshine when it reached 20.2C. Light wind so feeling very, very
muggy, a warm night ahead. Ideal conditions for raising the SST
though.

On the subject of warm nights, I believe the highest minimum
temperature ever recorded in Cornwall was at St Mawgan in August 2003
(23C) - Unless someone knows better!

Just looked out - bursts of sunshine again. Often the case near sea
level in SE facing Penzance under these conditions, nice hole in the
low crowd just over the seafront.

Misty on west facing coasts still www.chapelidne.com/php/surf_report.php
