Another heatwave could hit Wales this week with temperatures expected to reach 28C in parts of the country on Tuesday and Wednesday.
Forecasters say temperatures will reach around 26C by 4pm on Tuesday, marking the start of a spell of hot weather which is expected to intensify on Wednesday before remaining very warm into next week.
The hottest conditions are forecasted for Wednesday when Monmouth is expected to reach 28C. Newport and Chepstow, along with Wrexham, are also expected to be among the hottest places in the country this week.
The Met Office defines a heatwave in Wales as three consecutive days with maximum temperatures of at least 25C, with the threshold varying across different parts of the UK to reflect regional climates.
There could well be a heatwave in Wales this week, but it’ll likely be isolated to the east or south east of the country.
Eastern parts of Wales are expected to bear the brunt of the heat. Much of mid Wales is forecast to see highs in the mid 20s, while western coastal areas will remain noticeably cooler, generally in the low 20s.
Although temperatures are expected to ease slightly on Thursday, parts of the east of Wales are still forecast to remain at around 24 or 25C, which could tip us into heatwave territory.
Conditions will continue to be warm from Friday and remain so until around Wednesday next week, which is when temperatures are expected to return to more typical summer temperatures in the low 20s across much of Wales.
July has been 3C above average across the UK, according to provisional Met Office data, and with more than a month of summer left, the UK has already faced more days above 30C than ever before.
The prolonged spell of hot, dry weather comes as parts of Wales continue to experience exceptionally dry conditions following one of the driest Julys on record, increasing concerns over drought and wildfire risk.
Firefighters have spent days tackling a major blaze covering around 220 hectares of bracken and gorse at Blaenavon, while North Wales has also seen several large moorland fires as drought conditions tighten their grip on the region.
The combination of persistent heat, very low rainfall and dry vegetation has prompted repeated warnings from fire services for people to avoid lighting barbecues or campfires in the countryside.
Last week, Natural Resources Wales announced that parts of Wales are now in drought, saying that all of the country is experiencing prolonged dry conditions.
NRW said on Thursday that record-low river flows, back-to-back heatwaves and widespread wildfires have prompted the declaration of drought status in north Wales and the Upper Severn, causing problems for fish, wildlife and crops.
