Britain is baking under an unexpected September heatwave, with thermometers set to climb towards 30°C this week - making it potentially the hottest spell of the year.
The Met Office has confirmed that a plume of warm air from the continent will push temperatures significantly above seasonal averages, with the mercury peaking on Wednesday and Thursday.
Health Warnings Issued
Public health officials have urged vulnerable groups - including the elderly and those with respiratory conditions - to take precautions as the UK Health Security Agency issued a heat-health alert for southern and central England.
"This sudden spike in temperatures can catch people unawares," warned Dr Sarah Jarvis. "Stay hydrated, avoid the midday sun, and check on neighbours who might be at risk."
Transport Disruptions Expected
Rail operators are preparing for potential speed restrictions as tracks expand in the heat, while road surfaces may soften on some routes. Network Rail has activated its extreme weather protocols across southern regions.
Meanwhile, water companies have reassured customers that supplies remain stable despite increased demand, though they encouraged sensible usage.
Late Summer Surprise
This unexpected heatwave comes after an unsettled August, with meteorologists noting it's unusual to see such high temperatures so late in the season.
"While not unprecedented, September heatwaves of this intensity are relatively rare," explained Met Office forecaster Marco Petagna. "We're seeing temperatures 8-10°C above what we'd normally expect for this time of year."
The hot spell is expected to break by Friday as cooler Atlantic air moves in, bringing thunderstorms to some areas.
