In Penzance only 3 days this month have dropped below 11C! (only 2 on St Martin's Scilly)!

Temperature rose above 14C in west Cornwall (near sea Level) during the early hours. E.g 14.4C at 04:33 at St Ives

Also by record breaking (well based on my records!) mid December SSTs just offshore. 12.3C currently both the wave hub ( http://www.wavehub.co.uk/wave-hub-site ) , off the north coast, Penzance buoy off the south, and in St Mary's Sound.

Also, the suns just come out! Unexpected and pleasant surprise.
