Summary

London is set to experience its fourth heatwave of the summer, with temperatures predicted to soar to a high of 34C on Wednesday. This peak will be followed by a slight decrease to around 27C on Thursday. An amber heat-health alert is in place from Wednesday morning until Thursday morning, specifically for London and surrounding regions, warning of potential health risks, especially for vulnerable individuals.
The extreme heat has already prompted a significant response from emergency services. Over the weekend, the London Fire Brigade handled 2,729 emergency calls and responded to 1,345 incidents. These included multiple grass fires across the city, a blaze that destroyed 10 acres of grassland in Rainham, and fires affecting various properties. Fire boat crews also performed a rescue on the Thames.
This period of intense heat follows a record-breaking June for England. Forecasters anticipate warm weather will continue into the weekend, though temperatures will moderate slightly to about 26C. Other regions in the UK will experience more varied weather, with cooler, unsettled conditions expected sooner in northern and western areas, potentially including showers and a slight risk of thunderstorms.
