Wales saw its hottest day of the year so far over the weekend when 23.3°C was recorded in Porthmadog. The warm weather looks set to continue into the start of June, but some forecasters say reports an African plume heatwave is hitting the UK are exaggerated.
Channel 4 forecaster Liam Dutton says: "The coming weeks look likely to deliver typical warmth for the time of year. In other words, there are no signs of a heatwave or major warmth."
Dan Stroud, operation meteorologist with the Met Office says: "Currently we are expecting temperatures to subside a little over the next couple of days, before rising again on Thursday perhaps reaching 25°C across south east Wales."
