The United Kingdom is preparing for another surge in temperatures this weekend, which is expected to trigger the fifth official heatwave of the year by early next week. Forecasts indicate that parts of south-east England could see temperatures climb past 30C starting Sunday.
The UK Health Security Agency has implemented yellow heat-health alerts across the majority of England, lasting until Tuesday. These alerts highlight potential strain on social care and healthcare systems, while noting the elevated risk for vulnerable populations. Officials expect these advisories to be extended as the weather pattern intensifies.
Saturday will see a shift in conditions, with England and Wales reaching the mid-to-high 20s. Conversely, Scotland and Northern Ireland will remain cooler, experiencing cloud cover, intermittent rain, and winds with temperatures ranging from 17C to 21C. By next week, however, most of the UK will surpass local heatwave thresholds of 25C to 28C. This sustained heat is expected to fulfill the three-day duration required to classify the event as a widespread heatwave.
This year has been historic for the UK, marked by a record-breaking July that was the sunniest on record and the driest for England and Wales. The country has already endured 33 days above 30C, placing it on the verge of breaking the 1995 record of 34 days. Experts anticipate that temperatures could reach 35C in central and south-east England by the end of next week, potentially adding August to a list of months that have seen such extreme heat.
Dry conditions persist, with locations like Wisley in Surrey having gone 51 days without measurable rainfall. While some rain is expected in northern regions, there is no significant relief predicted for the drought-stricken south, meaning current hosepipe bans will likely remain in place. Farmers have already cautioned that the lack of moisture will lead to smaller and costlier produce.
