London: The UK heatwave has driven temperatures to new highs, with the Met Office forecasting peaks of up to 33 degrees Celsius on June 21. This may break the year’s temperature record for the second time in a row, after Suffolk became the first area to meet heatwave criteria by surpassing 27 degrees Celsius for three consecutive days.
Forecasters have confirmed that many regions are set to sustain temperatures above heatwave thresholds until at least June 22. London is expected to reach or exceed 28 degrees Celsius for a third day, confirming an official heatwave in the capital. Some eastern parts could even reach 34 degrees Celsius on June 22.
Health alerts have been in place across England since June 18 and will remain until 09:00 on June 23. The UK Health Security Agency has warned of higher health risks for older adults and people with existing conditions and has advised the public to stay hydrated and limit sun exposure during peak heat hours.

Despite the record warmth, temperatures remain below the historic June peak of 35.6 degrees Celsius recorded in 1976. The ongoing UK heatwave is driven by high pressure pulling hot air from Western Europe, combined with dry, windy conditions increasing wildfire threats.
Firefighters have tackled more than 500 wildfires across England and Wales since January, marking a seven hundred seventeen percent increase compared to the same period in 2024. Upon UK heatwave, Officials urge the public to follow safety guidance to prevent more fires while enjoying outdoor activities.
Some cooler weather is expected on June 23, with temperatures dipping to the high twenties in the south and east and mid twenties elsewhere. However, the Met Office continues to monitor the UK heatwave as conditions may intensify again in the final week of June.
