Checking all the Mays from 1901 to 2008 in Philip Edens GB weather
disasters book. Plenty of serious thunderstorms and rainstorms, but only
these wind events reported there.

Surprisingly little rain here in Penzance, in fact only 5.5mm in the 5 days ending 09:00 today, and very little since.

Windwise there was a 66mph gust near Lands End today, but that was a bit of a one off. That's on a par with places like St Catherine's Point and other south coast locations exposed to the SW. I do realise conditions were rather worse in exposed parts of S Wales.

Here in sheltered Penzance there was 38mph gust yesterday, 39 mph today. 2 days, 2nd May 2003 & 4th May 2004 saw gusts 50mph (55 & 52mph respectively.) The last significantly stronger gust was 48mph on 14th May 2013 when there was also 27.8mm of rain. A quick glance at my 30 records shows 32 days in May with stronger gusts than during this event. So in west Cornwall, nothing exceptional.

The most notable thing was the swell, I'd say a significant wave height of 24' must be rare for May, even out at Sevenstones. It's certainly comparable with the biggest swells of last winter. Small tides so no issues.
