UK given exact date July heatwave starts - but only two major cities hit

UK weather maps show the temperatures soaring with the dates of the next heatwave confirmed. July will see a mini heatwave hit as maps and charts, generated by WX Charts using Met Desk data, showing the maximum temperature soaring from the low-teens and mid-teens into the mid-20s and even high-20s.

Charts show temperatures will hit the mid-20s for many areas of Britain on Thursday, July 18. The forecaster predicts areas of the south east, including around London, will be warmest as the mercury skyrockets on the thermometer after a drab start to July.

Birmingham and the West Midlands will match the south in terms of temperatures, maps show, with 25C highs. The Met Office forecast from July 12 to July 21 reads: "Many areas should start this period mostly dry as a ridge of high pressure dominates the UK.

"It should feel pleasant enough in mostly light winds and sunshine, with temperatures generally near average, but some rural areas could experience chilly nights. However there is also a chance that rain may fringe into easternmost and southwesternmost areas at times.

"Then a transition to more generally changeable conditions looks most likely, though with a northwest-southeast split in fortunes. Northwestern areas will probably see more in the way of cloud and rain, whereas southeastern parts stand a better chance of longer periods of drier and at times, somewhat warmer weather.

"However, some rain may extend further southeast across all parts of the UK from time to time." The outlook for July 22 to August adds: "As can often be the case at this time of year, predictability at this range is low.

"There are some signs of a slightly greater than normal chance of a more prolonged settled spell developing at some point during the period, at least for a time, and perhaps more likely in the south. However, by the same token further, perhaps shorter, unsettled interludes are probable too.

"Above average temperatures overall, and drier than average conditions overall, are very slightly favoured."
