This morning the wind had aligned itself with the SW peninsula and as a result wind speeds were much less than yesterday when the NNE wind was funelling around the tip of Cornwall.

Late morning, under strong sunshine, the sea breeze effect turned the wind NE on the north coast, this reulted in much stronger winds there, but tended to kill the wind in Mount's Bay (I had a swim at 11:00 in unbroken strong sunshine & a light breeze.)

Now the fresh NE wind has reached Penzance, there was a rapid increase in wind speed around 13:00. There is now a very marked convergence zone where it meets the lighter easterly winds in Mount's Bay. It's resulting in a line of quite substantial Cu just offshore. It shows up very well on the satellite imagery since 13:00 http://www.sat24.com/en/gb It stretches way off Land's End http://www.landsendweather.info/

Deep blue sky and hardly a cloud either side of this zone.

Weather is rarely boring

I noticed that on the satellite picture this morning with a narrow band
of cloud streaming off the Penwith Peninsula heading out towards the
Isles of Scilly.

Virtually unbroken sunshine all morning until early afternoon with the
cloud over the land rapidly dissipating as it headed out over the sea,
leaving us with the usual case of overcast overhead but clear to the
south with lengthy spells of sunshine.

Then the wind picked up and the cloud managed to get further out over
the sea and obscure the sun. Then it all went rather cool, especially as
the DPs were unusually low at around 5C to 6C all day.

A maximum of 18.6C early afternoon but then dropped back as the cloud
encroached to around 16.5C for most of the rest of the afternoon.

Hopefully tomorrow looks like being sunnier and the forecast hints at
something more warmer and humid by Thursday.

Monthly sunshine total now at 84 hours.
