Two teenagers have died after encountering difficulties while swimming in open water amid a persistent heatwave across the United Kingdom. The incidents occurred as temperatures continued to surpass 30C, leading to extreme wildfire risk warnings and the implementation of hosepipe bans in several regions.

In Derbyshire, the body of an 18-year-old was recovered from the water near the Darley Abbey Mills complex on Friday. Emergency services were called after two young individuals experienced trouble in the water, and while one was rescued, the other was found deceased after an extensive search. Authorities have urged the public to avoid open water, citing dangers such as hidden currents, sudden depth changes, and underwater hazards that can quickly incapacitate even strong swimmers.

A similar incident occurred at Dovestone Reservoir in Greater Manchester, where an 18-year-old male was found unresponsive in the water on Friday evening. Police are conducting inquiries into the circumstances surrounding his death and have reiterated warnings about the dangers of open water.

The ongoing heatwave has also heightened the risk of wildfires. The London Fire Brigade (LFB) elevated the wildfire risk level in the capital from 'elevated' to 'extreme' over the weekend due to prolonged dry weather, heat, and wind speed. This warning comes after shrubbery caught fire near rail lines at Stratford station, causing disruptions. The LFB has advised against using disposable barbecues due to the heightened risk of ignition.

Several water companies have introduced hosepipe bans affecting millions of customers. Southern Water implemented restrictions for customers in Hampshire and the Isle of Wight starting Friday. Anglian Water announced a ban for over five million customers in the east of England, effective Saturday. Cambridge Water also initiated a ban for its customers, the first in three decades for the company. South East Water had previously introduced restrictions for areas in Kent.

These measures are a response to the strain on water supplies, exacerbated by successive heatwaves following a record warm spring. The situation is compounded by increased population and under-investment in water infrastructure, including a lack of new reservoir construction in 30 years and issues with leaking pipes.

Forecasters predict that temperatures will continue to exceed 30C in parts of England and Wales through the weekend and into the following week. The Met Office has noted that 2026 has become the first year on record to experience temperatures of 35C or higher in three calendar months, and has set a new record for the most days with temperatures of 34C or higher in a single summer. An amber heat health alert remains in place for large parts of England.

While some areas may experience thunderstorms from Monday, much of the country is expected to remain dry and warm. The Met Office has indicated that the focus of the heat will gradually shift towards western parts of the UK, with breezier conditions expected along southern coasts.
