To get rid of the sea fog. The sea off N cornwall is full of low cloud & fog, but notice how even the Penwith peninsula (west of Penzance) disperses the fog completely, even the top of the moors are clear http://www.greatbosullow.net/ and it doesn't reform to the south.

18.6C in Penzance (12:30) but only 11C in Camborne, which has been the place not to be yesterday & today - if you like sunshine. (So Norman might have found it refreshing!) It's regularly the coldest place in Cornwall in these conditions. The weather station is in a spot where the cold foggy air funnels up a valley. Even Land's End has topped 18C, which rather demonstrate how cold Camborne is.

Even just Cape Cornwall has totally protected Sennen. Ocassionally the fog rounds the Cape, but vanishes way before the beach. Nice pic of the sea fog bank here (scroll down to the 1st pic.) http://www.old-boathouse.com/acatalog/Diary.html

That was yesterday, but much the same today.

These marked variations over a mile or so make things very interesting.

Oh (OT) the dolphins I saw 2 days ago were Bottlenoed (according to people who should know). I thought they were the same pod that was seen surfing (yes dolphins do surf & they are very good at it - often using bow waves from ships) at Sennen the day before, but no, the pod was also seen in Moun'ts Bay at the same time.

Unless they have a Tardis there are at least 2 pods of dolphins around the tip of Cornwall at the moment, as well as increasing numbers of Basking Sharks & harbour porpoises.

Indeed, I would! I'm very pleased to be stuck indoors today typing a
report. Mind you, with the RH below 50% it's not too bad today. I
should think the local 'honey pots' are heaving. It's blissfully quiet
along our road, though.

On a related topic, there seems to be a great deal being made about
this being the hottest Early May Bank Holiday on record. One point that
isn't mentioned is that the date of the Bank Holiday varies because it
is held on the first Monday of May. 7th May is the latest date on which
this Bank Holiday can occur. At a time of year when long-term average
temperatures are rising day by day that must be a contributory factor
to today's high temperatures. This is only the 6th year out of the past
40 on which the Bank Holiday has occurred on the 7th. In all other
years it has been earlier by between 1 and 6 days. Currently it's
24.9° in Tideswell and still creeping slowly up. That's not
exceptional for May as a whole but might be this early in the month - I
haven't checked. There were 2 hotter days in May last year. One of
these (25.8° on the 26th) might eventually be beaten today but the
other (27.4° on the 25th) looks fairly safe.

Sea breeze effect has killed the N wind in Penzance and it's now hit 20C, as it has across much of Cornwall. The warmest day of the current spell here.. Outside the Harbourside Cafe an hour ago, with no wind, strong sun and high humidity it felt very warm indeed. Still only 11-12C in the fog at Camborne & Newquay. In fact you can see the north coast sea fog around Hayle from Penzance.

I've rarely seen the prom so packed, even in August. A combination of a well forecast sunny Bank holiday & fog on the north coast.

Very high temperatures are rare here before June, but 5th May 1995 hit 24.0C. That's earlier in the month & a good deal warmer than today.

During the last hour or so the wind has backed a bit, brought the sea fog well over the north coast, and even here in Penzance, although it is still sunny, the temperature has dropped back to 15C.

Similarly, at Cardinham, the temperature has dropped 6C (21c - 15C) in 2 hours.

Interesting day.

I've just looked back over my records since 2005 and my warmest 7th May
was in 2008 with 25.4C. That May is the one to judge all others by for
warmth. In most Mays the temperate doesn't regularly start to climb
above 20C until the last week such is the cooling effect of the sea.

A maximum of 24.9C at 13:45 today before the sea breeze gathered
strength and cooled things down a little.

I cannot think of a more stunning 3 days with perfect temperatures and
humidity. Fell asleep in the hammock this afternoon listening to the
skylark and thrush singing their little hearts out. The cooling breeze
bringing in scents of the sea and taking the edge of that scorching
sunshine. Magical.

The other thing that seems rarely to be mentioned in the media is that
this bank holiday has only been going for forty years, making the record
sound much more significant than it actually is. I imagine that many
people ages less than 45 or so will have assumed that the holiday has
been going for a hundred years or more.
