The UK is currently experiencing its third heatwave of the year, with temperatures expected to reach a scorching 35C (95F) on Thursday. This prolonged heatwave, which began earlier this week, is not just about breaking temperature records; it's about the impact and longevity of the heat. While it won't surpass the June heatwave's peak of 37.7C in Lingwood, Norfolk, the current heatwave is still remarkable due to its extended duration.
On Wednesday, Heathrow Airport hit 33.8C, and Wales, Scotland, and Northern Ireland all recorded temperatures in the low to mid-20s. By Friday, the heat will spread further north and west, reaching the Midlands and southern Wales, with temperatures in the low to mid-30s. However, eastern areas will experience a slight cooling breeze due to an easterly wind.
The heatwave's impact is significant, with Amber and Yellow heat health alerts in place across various regions. These alerts indicate potential strain on health and social care services, including a rise in deaths, especially among the elderly and those with health conditions. The National Fire Chiefs Council has also warned of increased wildfire risks, urging people to avoid disposable barbecues in open areas.
The heatwave criteria are stringent, requiring three consecutive days of temperatures above specific thresholds. Many areas have already met these criteria, including parts of the south and east of England, the West Midlands, and southern and southwest England. This heatwave is one of the longest since 1976, with temperatures expected to remain well above average for the next 10 days.
Looking ahead, forecasters predict higher-than-normal chances of hotter weather throughout July and August, with significant heat spikes expected in the UK and Europe. This aligns with the warming climate, where hotter summers are now twice as likely as in the 1991-2020 period. The question remains: will another heatwave follow this one, and what does this mean for the future of UK weather?
