The UK has set new records for May temperatures for two consecutive days, with Kew Gardens in London reaching 35.1°C on Tuesday, surpassing the previous day's record of 34.8°C. Wales also experienced record-breaking heat, with Cardiff's Bute Park recording 32.3°C. These extreme temperatures have led to six amber heat health alerts from the UK Health Security Agency, warning of significant impacts on health services. The heat has caused disruptions in train services across the country, with Network Rail implementing speed restrictions to ensure safety. Additionally, many areas in England and Wales are officially in a heatwave, as temperatures have exceeded the required thresholds for three consecutive days. The Met Office attributes this early season heat to a high-pressure system and notes that such temperatures are consistent with the long-term trend of rising temperatures due to human-caused climate change. The heatwave has also resulted in several tragic incidents at swimming spots, prompting safety warnings from the Royal Life Saving Society.
