The immediate coast is often sunnier than a short way inland in May/June, but this year the difference appears to have been huge. (The lack of sunshine recorders means I can't be absolutely positive, just 99.9% so) There's also been an lack of sea fog. 
This morning continues the trend. Sennen 09:00, already Cu <1mile inland.
No real swell now, 2/3 days ago saw the biggest swell of the month, though still with some coastal sunshine.

Beach was red flagged, on this occasion it needed to be. The size of the cars gives a vague idea of the size of the waves (8-12')
