Britain could experience a second heatwave in August, with temperatures potentially reaching the mid to high 30s Celsius, according to weather forecasters. This follows the hottest day of the year so far on Tuesday, July 30, when the mercury hit 32C in Kew Gardens and Heathrow, London.
Exacta Weather forecaster James Madden has predicted a "major heat surge" from around August 10 to August 15, which could bring the hottest temperatures of the summer. He warned that values could rise into the low to mid 30Cs, with a "more extreme possibility" of reaching mid to high 30Cs in the hottest parts of the country.
However, the current hot spell is also bringing the risk of thunderstorms. The Met Office has issued a yellow warning for south-eastern and southern England on Wednesday, July 31, and a more widespread warning across England and parts of Wales on Thursday, August 1. Temperatures are expected to cool over the weekend before the second heatwave arrives.
Met Office meteorologist Clare Nasir said Wednesday would see strong sunshine and temperatures rising quickly across England and Wales, with 30C to 32C in the far south of England, and 26C to 28C in Wales. Scotland and Northern Ireland would see a pleasantly warm 20C to 21C.
If the predicted temperatures are sustained for at least three consecutive days, it would constitute an official heatwave. The Met Office defines a heatwave as when daily maximum temperatures meet or exceed a threshold that varies from 25C to 28C depending on the county.
