UK Swelters: Hottest Day of the Year So Far!
8 Apr
Summary
- Temperatures reached 26.5C in Kew Gardens, London.
- This was the hottest April day since 1946.
- Cooler, rainy weather is forecast for Thursday.

On Wednesday, the UK recorded its warmest day of the year, with temperatures peaking at 26.5C in Kew Gardens, south-west London. This figure represents the hottest April day observed in the first half of the month since 1946. The warm weather is attributed to high pressure drawing warm air northwards, making temperatures significantly above average for early April in many parts of central, southern, and eastern England.
London's high temperatures even surpassed those in holiday destinations such as Ibiza, Rome, and Marrakech. The previous warmest day of the year was Tuesday, when 24.8C was recorded in Anglesey, Wales. Despite the notable warmth, the conditions do not officially meet the Met Office's definition of a heatwave.
Forecasters anticipate a change, with rain and cooler, showery conditions expected to move across the UK from Thursday onwards. This brief spell of warm weather is concurrent with peak pollen season, with ash and birch pollen levels reported as very high.
