I know this is tempting fate, but most days for a while mist/low cloud
has been forecast for the south Cornwall coast, but it hasn't
materialised. With a dewpoint of 7-10C in Cornwall, and a SST of 11C
(11.2-11.4C in Mount's Bay) the risk of sea mist on the south coast
would seem fairly low. Sunshine hazy with a fair bit of high cloud
ahead of the front to the west. Southerly wind still light (around
5mph at the exposed heliport).

Nice wave on the north Cornish coast, which is the place to be today,
it's likely to be 3-4C warmer than the south coast.
