UK Hit by Second June Heatwave with Amber Alerts and Wildfire Warnings
What happened
The UK is enduring its second June heatwave, with temperatures expected to reach 30–34 °C, making it hotter than Ibiza, according to the Met Office. An amber heat-health alert has been issued across England, warning of increased health risks, including hospitalisations and potential deaths, especially among older people and those with pre-existing conditions. The heat comes on the back of the driest spring in over a century, prompting wildfire warnings and voluntary water-conservation measures by water companies.
When – The second June heatwave starts this weekend, with temperatures expected to hit over 30C.
Record breaker – On 21 June 2025, the UK recorded its hottest day of the year so far with temperatures reaching 33.2C in Carlwood, Surrey.
What next
This intense heat is likely to continue through the weekend before easing next week. Authorities are urging caution: stay hydrated, limit sun exposure, check on vulnerable people, and take care with outdoor fires and barbecues. The record-breaking warmth underscores how climate change is making UK heatwaves more frequent and severe, with experts warning of future extremes, including possible 40 °C days and tropical nights, demanding improved readiness and infrastructure resilience.
The impact – Lots of summer events will be affected by the heat, including Wimbledon and Glastonbury.
The future – Heatwaves are becoming more common due to climate change, with a greater chance of seeing extreme heat regularly.
