Wales' weather forecast as Met Office predicts when and where heatwave will hit

Summer is poised to make a grand return next week with temperatures predicted to rise once again. After a cooler start to June with below-average temperatures the end of the month is set to compensate with highs of 27C expected in parts of Wales.

The Met Office has hinted at the possibility of a heatwave with several consecutive days of warm weather anticipated across the UK. An official heatwave, as defined by the Met Office, is a period of at least three days where the temperature exceeds a certain threshold.

From Monday, June 24, to Thursday, June 27, much of the UK will experience temperatures well into the mid-20Cs with some areas reaching a scorching 29C. In Wales most regions will enjoy warmer weather with temperatures hovering around 22-24C. However a large swathe of the southeast can expect temperatures between 25C and 27C.

A recent Met Office chart reveals the areas likely to see the warmer weather with the southeast of England predicted to be the hottest with temperatures soaring to 29C, reports Wales Online. At present areas in southeast Wales appear set to be the warmest this side of the border, hitting 26C in Chepstow on Tuesday and 25C in Monmouth. Wrexham could see highs of 25C too while Cardiff is expected to reach around 23C and Swansea 22C.

Neil Armstrong, a chief forecaster at the Met Office, stated: "After a brief, less settled, interlude on Friday and Saturday fine conditions will return by Sunday and into next week. For much of the UK this will be accompanied by a boost in temperatures with many places reaching the mid-20Cs by the middle of next week.

"Some central and southern areas are likely to see temperatures approaching the values needed for heatwave conditions. Heatwave conditions need to remain in situ for three consecutive days and by the middle of next week it is possible that some parts of the UK could be reaching heatwave thresholds. However, whether or not everyone experiences heatwave thresholds, the majority of the UK will experience the finest conditions and highest temperatures so far this year."
