A man in his 30s has died after being swept out to sea by the current after falling from his kayak during the heatwave over the weekend.
Emergency services rushed to the Dee Estuary, off the coast of Caldy in Wirral, Merseyside, at around 3.30pm on Saturday after receiving reports that two kayakers were in danger.
One of the pair was able to return to shore unaided but the second man had to be rescued by the Coastguard and was airlifted to hospital.
Police then confirmed the tragic news of his death shortly afterward.
West Kirby RNLI said its crew set off within 10 minutes but found the kayak was empty when they located it.
They then requested assistance from Hoylake RNLI’s hovercraft and the HM Coastguard helicopter to aid the search and rescue operation.
In a post on Facebook, RNLI West Kirby Lifeboat wrote: "West Kirby Lifeboat paged to search for 2 Kayakers missing on the River Dee.
"The crew launched within 10 minutes and upon finding an empty kayak West Kirby Lifeboat requested the launch of Hoylake RNLI’s hovercraft and the HM Coastguard helicopter.
"West Kirby Lifeboat commenced a search pattern to attempt to locate the casualty as did Hoylake RNLI’s hovercraft from the opening of the estuary adjacent to Hilbre Island.
"Flint RNLI’s inshore lifeboat was also launched and a search of the Welsh side of the estuary carried out. West Kirby's BV206 tractor searched the waterline alongside a search of the shoreline by local HM Coastguard units.
"One casualty returned to shore unaided and the second casualty was located by HM Coastguard helicopter who immediately transferred this casualty to a hospital in Liverpool."
Richard Diamond, West Kirby RNLI lifeboat operations manager, said: "We would encourage people to carry a means of calling for help and keep it on you.
"If you find yourself in the water unexpectedly, fight your instincts and float until the effects of the cold water shock pass."
A spokesperson for Merseyside Police said: "We can confirm that Merseyside Police were called to the death of a man in his 30s rescued from the water off the coast of Caldy on Saturday, June 12.
"Around 5pm we received a report from the Coastguard that a man had fallen from his kayak into the water and was swept away by the current.
"The man was rescued by the Coastguard and taken to hospital via helicopter. Sadly, he was declared deceased a short time later."
They went on: "The man’s next of kin have been informed.
"The death is not being treated as suspicious and a file will be prepared for the coroner."
