From Penarth News, 21st June.

In Penarth today an on-shore easterly breeze (despite what the BBC weather chart says) is keeping it slightly cooler than in baking Cardiff – or London where temperatures are expected to reach 34C.

Today is the summer solstice – the longest day of the year – when Penarth is set to enjoy 16 hours and 38 minutes of daylight. The sun  rose at 04:43 and sets at 21:31 .

The heatwave is expected to end tomorrow – as the nights start drawing in.
