Just topped 20C in Penzance. More remarkable is that the SST is >14C off the south coast of Cornwall. The warmest anywhere in the UK (even the bouys up the Severn Estuary) and >2C above the early May norm.
It's been so dry even SW Water's storm overflows have virtually (though certainly not entirely) stopped overflowing, they'll go mad again once there's a shower. It does mean the seea is incredibly clear.
Some patches of dense cirrus now ahead of the thundery low, though no convective cloud below it this near Lands End.
On a recent BBC Spotlight SW Water interrogation(?) they got away with saying the number of pollution events at 'bathing waters' were lower last year. They didn't mention that certain beaches almost continuously polluted (e.g. Mousehole) were strangely not designated bathing waters anymore. Or indeed that certain monitoring points (like near the sewage pipe at Porthgwidden St Ives) were mysteriously turned off/not functioning whenever it rains. Or that when pollution is reported from a monitoring station it is often dis-regarded as the reading is suspect.
