Two people have died after getting into difficulty while swimming, as the 30C-plus heatwave continues across the country. The bodies of two 18-year-olds were recovered yesterday in Derby and Greater Manchester, with the police urging the public to avoid entering open water amid the rising temperatures - which are set to last for days. The deaths come as much of the east of England came under a hosepipe ban today, as 2026 marked the first year to see temperatures of 35C or higher in three calendar months. Emergency services also warned of 'extreme' wildfire risks over the weekend. Derbyshire fire crews battled two wildfires on Friday evening, and the London Fire Brigade (LFB) heightened the risk level in the capital from 'elevated' to 'extreme' over the weekend due to prolonged dry weather, heat and wind speed. In Derbyshire, an 18-year-old teenager's body was recovered from the water below the weir near the Darley Abbey Mills complex on Friday. Emergency services had been called at 12.46pm after two young teenagers got into difficulty in the water. The younger teenager was rescued, but after hours of searches, the 18-year-old was found dead.

Entering the water may seem like a quick respite from the heat, but it is extremely dangerous.'Hidden currents, sudden changes in depth, underwater hazards and cold-water temperatures can cause even the strongest swimmers to get into difficulty within seconds.' In Manchester, emergency services were called to Dovestone reservoir in Oldham at around 7pm on Friday. They found the 18-year-old unresponsive in the water and he was pronounced dead at the scene despite efforts of medical professionals, the force added. A scene remains in place and inquiries are ongoing, police said.Detective Inspector Steven Horton, from the Greater Manchester Police, said: 'We have tragically recovered the body of an 18-year-old man from the water and are conducting extensive enquiries to establish the full circumstances.'Our thoughts remain with his family and friends during this incredibly difficult time.Photos taken just a few years apart show the dramatic change in the landscape in Cambridge Water firms have also announced hosepipe bans for the east of England, Cambridge, Hampshire, the Isle of Wight and areas of Kent due to a strain on water supplies.

The current heatwave across the UK looks set to continue, as this year was the first on record to see temperatures of 35C on six separate days and emergency services have warned of an 'extreme' wildfire risk over the weekend. The LFB urged people not to use disposable barbecues this weekend over fears of the dry heat leading to fires. The Metropolitan Police is also concerned about excessive calls, with England set to play Norway in a quarter-final of the Fifa World Cup tonight. The Met urged people to avoid getting in touch for non-emergencies amid a surge in 999 calls during the hot weather. Forecasters said areas of England and Wales will continue to exceed 30C throughout the weekend and into next week.

Amber and yellow heat health alerts issued by the UK Health Security Agency will remain in place across large parts of England until Sunday.The Met Office warned of possible thunderstorms from Monday in parts of the south, but overall predicted another very dry week ahead. Met Office deputy chief forecaster, David Hayter, said: 'Areas of central and southern England and Wales are expected to see several more consecutive days of temperatures above 30C.'While temperatures are expected to reach into the low to mid-30s through the weekend, the focus of the heat will gradually shift towards western parts of the UK.'This will also bring some slightly cooler and cloudier conditions to eastern coastal areas than of recent days. It will also turn windier across southern areas, bringing breezier conditions, especially along coasts and headlands.'The main exception to the largely dry and sunny conditions is northern Scotland, where a cold front is bringing rain, cloud and some heavy downpours on Friday. But conditions are expected to improve over the weekend.'There is a possible increase in thunderstorms from Monday in parts of the south, however most areas will remain dry, sunny and very warm into the coming week.' Meanwhile, in Scotland the weather appeared not so sunny. Play was suspended due to fog on day three of the Genesis Scottish Open 2026 todayThe Met Office announced the new records after temperatures peaked at 35.2C at Coton in the Elms, Derbyshire, on Friday afternoon.Later in the evening, Derbyshire Fire and Rescue (DFR) confirmed that it was currently fighting two wildfires in the area.The service reported that it was dealing with a moorland fire near Arnfield Farm in Glossop, and a separate ongoing fire in Tintwistle Moor.Friday night also saw a 'trackside' blaze involving shrubbery at Stratford Station in London at around 7pm, causing rail line closures.LFB reported that the fire was under control at around 9.30pm, and reiterated the risk of wildfires during the heatwave this weekend after the incident.The brigade said latest assessments show the risk in London will grow from 'elevated' to 'extreme' from Saturday to Monday, driven by factors like prolonged dry weather, heat and wind speed.LFB assistant commissioner Tom Goodall said: 'We want everyone across the city to enjoy the continuing heatwave but this must be done responsibly.'The former 35C on separate days record was held by 1976 and 2020, during which five days were recorded with temperatures over 35C. 2026 has also become the first year to see temperatures of 35C or higher in three calendar months - and broke the record for the most temperatures of 34C or higher, with nine so far this summer.Water firms have also announced hosepipe bans for the east of England, Cambridge, Hampshire, the Isle of Wight and areas of Kent.Strain on water supplies has intensified after the successive heatwaves followed a record warm spring for England and Wales.It comes as the UK faces growing pressure on its water system as human-driven climate change disrupts rainfall patterns and drives more extreme weather events.This has been compounded by population increases as well as years of under-investment in infrastructure putting further strain on the system, including no new reservoirs being built in 30 years and leaking pipes.Hosepipe restrictions came into force on Friday for about one million Southern Water customers across Hampshire and the Isle of Wight.On Friday morning, Anglian Water also announced a hosepipe ban for its more than five million customers in the east of England.The ban will come into force from 1am on Saturday but the utility has asked that people 'live within the spirit of these restrictions immediately'.In a notice on Thursday afternoon, Cambridge Water announced a temporary hosepipe ban for its 350,000 customers, which came into effect immediately but enforcement actions will not start until 1am on July 17.This marks the first time in three decades it has introduced the restriction, with the company saying teams are working around the clock to maintain supplies.South East Water became the first to introduce a ban on July 3 for areas of Kent, including those in Ashford, Canterbury, Faversham, Maidstone, Sevenoaks, Snodland, Tenterden and Tunbridge Wells.
