Sun seekers are being urged to not take a dip in open water despite the warmer weather.
Strong currents that could pull you under, sharp rocks beneath the surface, and cold water shock are all real risks for those who go into water.
And despite this week’s heatwave bringing soaring temperatures, the County Durham and Darlington Fire and Rescue Service (CDDFRS) has issued a cold water warning.
It comes weeks after County Durham mum Fiona Gosling - whose son Cameron died after jumping into the River Wear, in Bishop Auckland, in 2015 - urged parents to speak to their children about the dangers of water.
Cameron, a 14-year-old from Crook, suffered cold water shock when he hit the freezing water - a condition which can affect your breathing and movement - and he sadly drowned.
There was also a recent double water tragedy at Seaton Carew last month where Wayne Taylor and Ian Pascoe died trying to save Mr Taylor's two sons when they got into trouble in the sea.
A CDDFRS spokesperson said: “When we think about water rescue incidents, I think quite often we all think about these really, really dangerous pieces of water.
“And the thing is, is that many rescues that we go to are exactly like what's behind me now. They are beautiful places to be. They do not look dangerous at all.
"But what can happen is we enter the water later on in the day, we can then start to get into cold water shock.

"It's where our body, without us wanting to do it, will give us a gasp, try to make us breathe, but that will be underwater.
“So we take water into our lungs and we can lose the ability to swim. When this happens, what we can do is then float to live.
"So this is simple as you float onto your back, you put your head back, put your ears into the water and put your hands out and make that motion to start to swim and try and keep calm as possible.”
