UK Heatwave: 23C Highs Before Autumn Chill
15 Oct
Summary
- Temperatures are reaching 23C in parts of eastern England.
- Warm air is being fed across the UK by low pressure near Iceland.
- A cold snap with temperatures as low as -4C is expected by Sunday.

Parts of the UK are set to enjoy a final dose of autumnal warmth, with temperatures climbing to 23C in some eastern areas on Thursday. This toasty weather is attributed to a deep low-pressure system near Iceland feeding warm air across central, eastern, and southern parts of the country. Several areas, including London, Norwich, and Sheffield, are expected to reach 21C.
However, this warm spell is transient. By Friday, temperatures will cool significantly, with London seeing around 16C. A more dramatic shift is anticipated towards the end of the weekend, as a cold snap is predicted to bring temperatures as low as -4C, particularly in the north of the country.
