Today it reached only 17.0C in Penzance, despite prolonged sunshine (over 80% of the possibly sunshine today - so far - even up on the moors at Bosullow http://www.sunrecorder.net/googlemap...serial=1000 5 )

Maximum temperatures 17.5C are unusual in Penzance late July / August, as this is approximately the SST - though over the last 10 days it has dropped by from 17.5C to 16C, even lower where the wind's offshore.

Taking late July to be 21st - 31st then, during the period 1992-2015, there have been (including today) only 4 days when the temperature has failed to reach 17.5C

These a-
20/7/11 15.7C - Dull, occasional rain.
24/07/15 16.4C - Showery rain, some late afternoon sunshine prevented this being a new cool record.
26/07/09 17.0C - Rain all day.
and today
30/07/15 17.0C - Long periods of sunshine.

So today is a new 'cool' record for a late July sunny day.

That is cold for Penzance in July!
Another cool, cloudy, showery day here.

Turned into a lovely day here. Prolonged sunshine & very little wind made the still below normal maximum of 18.8C feel like summer.

Calm sea conditions, an ideal jumping off the breakwater day http://www.sennen-cove.com/index.htm .

Could be good surfing Monday afternoon, if GFS has it right (around 10mph SW broken cloud), far too much wind if the MetO is right (18-20mph). All down to how the old isobars spread just after the cold front goes through. There's normally a quiet hour or so whatever the forecast. Magic seaweed shows the quiet slot with a 4-6' wave around noon. http://magicseaweed.com/Sennen-Surf-Report/4/
I seem to be getting sidetracked.
