In June 2025, England observed its warmest June since record-keeping began in 1884, achieving a mean temperature of 16.9 degrees Celsius. The UK also experienced its second-warmest June on record, while June 30 marked the hottest day of the year at 33.6°C in southeast England, surpassing the previous record of 33.2°C from earlier in the month, according to Indiatimes, Channel News Asia, and AA.

The scorching temperatures were a result of two heatwaves affecting parts of England and Wales throughout June, contributing to the trend of increasingly warm weather across the UK, which had also recorded its warmest and sunniest spring in over a century. The nation’s weather patterns highlight a departure from its typically cooler climate, as noted by the Met Office, which stated that human influence has increased the intensity of extreme heat events, according to Indiatimes, Channel News Asia, and AA.

In response to the extreme conditions, amber heat health alerts were implemented across parts of England, warning about the risks to public health, particularly for vulnerable groups. The National Health Service advised the public to remain indoors, avoid strenuous activities, and use sunscreen, highlighting the broader implications of heat waves on health services, as emphasized by Indiatimes, Channel News Asia, and AA.
