Temperatures 25C are rare in Penzance in June, as the sea's still relatively cold.

26.6C today (& it may rise further) with the wind tracking down the peninsula. It was onshore, but a weak north coast sea breeze has pushed it offshore.

That makes it the 3rd= warmest June day on record at my station (records start 1991) after
30th June 1995 27.9C
27th June 1995 27.0C

A spell of offshore winds pushed the temperature to 26.7C at Lands End

Reached 26.9C at Bosullow over the moors, also 25C @ Culdrose & 25C at St Mawgan currently (16:00 ish). All exposed locations.

Those in the SW might have seen DB on Spotlight showing a maximum of 24C for Penzance today. He can be extremely careless with figures. On one occasion I challenged him when he gave a ludicrous rainfall figure for Penzance, turned out it was for Cury (near the Lizard point), but Penzance was 'the nearest town' - which it isn't.

Lands End, Bosullow on the nearby Moors & my station reached 27C, to the nearest degree, and Lands End Airport reached 26C. Even Culdrose with the wind off Falmouth Bay reached 25C.

It reached 29.5°C here Graham making it nearly the hottest June day I've
recorded, beaten by that remarkable June day in 2017 with 31.1C on the 20th.

For the temperature to get anywhere near 30C the sea breeze has to fail,
and it did today allowing the humidity to rise and the dew point reached
a high of 21.3C making for a quite humid afternoon with little or no breeze.

I don't watch David B or Spotlight any more. Nor any 'news' output by
the Biased Broadcasting Corporation. I'm now blissfully ignorant of his
dodgy data.

Wow, and to my amazement I have discovered a forum area dedicated to Penzance weather actually exists! Just found this online whilst searching the Web for your weather records and data Graham, I've just signed up here on Wx Banter now!

Reached a high of 26.5C here in Madron on 24th, I wasn't sure how unusual that was for June but know now that is pretty rare for us down here! Peaked at 25.3C the following day 25th around late morning, pretty exceptional.

We seem to benifit quite well here from those N/NWly sea breezes. Not sure if down there in Penzance you see more of the S/SE'ly onshore? Here a couple miles inland it is most often N/NW'ly which almost gives a bit of a foehn effect with the hills up to 250m - opposite is seen in Camborne without the hills!
