The hottest June on record has given way to torrential rain, plummeting temperatures and strong winds - with more set to come in the days ahead. While last month saw parts of the country top 30C, so far this month we have struggled to get over 20C - and the Met Office says another cool front is on the way.
BBC Wales weather presenter Derek Brockway has explained why the weather has changed so sharply, as we get deeper into summer, a phenomenon people in the UK are used to in July and even August
He said: "It often changes in July after a good spell in May and June. Seen it happen in numerous summers over the years. And the Welsh for July is Gorffennaf which means 'end of summer'. August is the wettest summer month on average in Wales and autumnal."
