Long sunny periods right on the coast, largely unbroken near Land's End. Plenty of cloud bubbled up just inland. A 'wave' on the front to the east did make the sunshine milky around noon, but not for long.

As a result the highest temperatures were right on the coast. 15.4C at St Ives, 15.3C in Penzance, 15.4C St. Martin's Scilly. Due to the land based cloud, even the most exposed coastal spots were a couple of degrees up on just inland. E.g. Land's End 14.7C, Camborne 13C.

The front did give some heavy bursts of rain last night, 7.8mm here in Penzance, but the sun was out by the time I emerged.
