Temperatures in parts of the UK could reach as high as 26C on Tuesday, particularly in the south-east of England. The BBC weather report indicates that many areas across England will experience temperatures in the 20s Celsius, with unusually mild conditions expected overnight.
This warmth is projected to be around 3C to 7C above the typical late September average, which ranges from 16C to 19C during the day and 7C to 11C at night.
Wales, Northern Ireland, and Scotland are also expected to see warmer-than-average conditions, with daytime highs forecasted between 17C and 22C on Tuesday.
The rise in temperatures is attributed to a strong southerly airflow bringing warm air from France and Spain, where temperatures have exceeded 30C. Although there may be some cloud cover and a few showers in the morning, sunny spells are anticipated to develop over England and Wales.
The southerly winds are expected to strengthen, with gusts reaching up to 50mph in Northern Ireland and western Scotland, linked to a deep area of low pressure moving north in the eastern Atlantic.
Nighttime temperatures may not drop below 20C in some areas, which is significantly warmer than the typical late September range. Overall, minimum temperatures are expected to be around 15C to 19C.
September is on track to be another month of above-average temperatures, with the Central England Temperature record indicating a rise of 2.6C above normal for the month up to the 26th. This trend suggests that 2026 could be one of the warmest years on record for the UK, barring a significant drop in temperatures for the remainder of the year.
