A recent thread included comments regarding recent weather, in particular (from my perspective) using Camborne for a fair chunk of Cornwall.

The real issue here is the big differences between the north & south coasts, depending on wind direction, cloud cover / sea fog & as was the case yesterday, sea breezes.

Under near calm conditions there is a distinct sea breeze cycle here. The south coast sea breeze kicks in 1st, due to the morning sun. The NW facing north coast sees strongest heating PM, and a later sea breeze. In Penzance, taking yesterday as a typical example there was a moderate onshore sea breeze from noon to 17:00, then it was calm, but 19:00 the north coast sea breeze reached the south coast, as it frequently does early evening.

This meant that in Penzance the temperature reached 20.2C around noon, fell back to near 18C mid afternoon. It then reached the maximum of 20.5C at 18:30, absolutely nothing like Camborne where it was around 4C colder at that time.

Today, with more of a northerly gradient wind, the difference could well be greater. Now, if you get sea fog on one coast the difference can near 10C.

None of this is reflected in the forecasts sadly. Penzance, where the wind is forecast to be offshore all day, and that seems likely - 19C during early mid afternoon. Sennen BEACH, where there is a directly onshore 12mph wind forecast, and the webcams currently show a distinct onshore breeze (means the sea will be warmer, air cooler) 19C during early mid afternoon. If I was to predict I'd say Penzance 21C (possibly higher) Sennen beach mostly 16-17C, unless the breeze drop out.

What ever happened to a smaller grid picking up local detail? It can't even distinguish between coasts facing in & out of the wind.

You'd be amazed Graham if you saw the super high res raw output. But then
the commercial arm of the MetO would not be pleased if you did LOL.

Do you mean his money is counterfeit or that he is a pirate?
I believe he comes from Cornwall, so the latter is not unlikely.
Has he got a parrot and a wooden leg, I wonder?
(That's always a good sign in a negative positive kind of a way.)

There are a lot of us, a typical afternoon in Penzance http://www.thisiscornwall.co.uk/imag...9912-large.jpg

Meanwhile, the temperatures just hit 21.6C, the highest of the year so far.

Beat you, a sweltering +21.9C up here on the Haytor mountain in unbroken hot
sunshine.
Far too hot to be outside though! Roll on January :-)

So 'tis a matter of paying back the taxpayer in his own coin, arr?
Fraud, larceny and lies?

Arr, me hearties. Arr!
Bring me the head of Climategate and we'll cook it in the sand. Let's make it hot for 'em.

Good old Met Office! Don't give it away if you can sell it. What if someone involved with the hi-res output leaked the results to whoever is responsible for the public forecasts? Dismissed on the grounds of commercial naivete? What fun - what an awful place. How on earth did it get like this? That's a rhetorical question; we all know how it got like it.

Yes, apparently they are able to forecast, but prefer to put out a load of c**p, what a success story. Perhaps the appalling website design is an to hide the forecast. It's all such a shame, because with a bit of human effort and indeed interest, it could all be so much better.

It turned out much as common sense (something the model output totally lacks) would predict.

Max temperatures away from the north coast:-
Culdrose 22C
Penzance 22.7C (warmer than you Will & highest of the year so far)
Land's End (the station is actually near Porthqwarra facing SSW, so wind offshore) 22C

Near the north coast
Camborne 18C
Right on the north coast, a particular exposed cliff top site
The Island St Ives 17C

Another lovely day in very strong sun wherever you were. UV hit 9 on St. Martin's Scilly, about as high as it gets.

Nice bit of bodyboarding with another USW contributer on Weds.

Yes I appreciate that the Met Office is not a fully private business,
but as I understand it they no longer get given a big wad of cash from
the government to do with what they like, and have to raise revenue from
commercial ventures.

Well yes, except there was a time when there were service industries, whose function was to provide say, the best forecast they could manage to people who might need it, not just those with a wad of cash.

Of course those were the days when directory enquiries were free, and you normally even got given the right number. I know the horrors of working for a big organisation, I once worked for BT.

Strangely, many 'purely business' sites do a much better job, for a proper beach forecast http://magicseaweed.com/Sennen-Surf-Report/4/ possibly because being fairly specialised, the people involved are genuinely interested in what they are doing, not just passing the day pressing a few buttons on a PC in a darkened air conditioned room.
