I often wonder why Camborne is quite so cold on a sunny summer's day. I'm sure the readings are OK, it is a manned station after all. I can only assume the sea breeze funnels up the valley the station sits in.
Even so, with todays fairly gentle N breeze, the sunshine means even on the exposed cliff tops at both Lands End & Newquay airport, it was 17C at 13:20. More exposed spots in an onshore breeze you'd be hard to find. Away from the immediate north coast it's 18C even up at Culdrose on the windswept Lizard plateau.
Meanwhile, Camborne 15C. The reports say mist, it isn't it's haze. Everywhere in west Cornwall has visibility only 4-8miles. Current webcam from Gwithian the nearest coast to Camborne. Same at Sennen this morning, though the sunshine was strong. Same in Penzance, Culdrose etc.
It is extremely hazy despite the wind coming around an anticyclone just to the west. Normally I'd expect the visibility to be excellent in these conditions.
