With warmer weather having made an appearance, Wakefield Council is reminding everyone to stay safe and keep away from potential dangers.
The Council is urging people to be aware of the risks of cooling off or playing in ponds, lakes and flooded quarries.
It is dangerous to swim in places that are not specially created for swimming. Although open water can look inviting on hot days, there are often hidden dangers underneath, such as discarded waste that can entrap people, slippery rocks and changes in water depth. Shallows can also be dangerously cold when they get deeper.
Cllr Maureen Cummings, Wakefield Council's Cabinet Member for Environment and Communities, said: "During hot weather some people may be tempted to go into the water for what appears to be a cooling dip, but swimmers have no idea of what is under the surface.
"Tangles of weeds and rubbish could ensnare a swimmer and put them in danger of drowning or severe injury. The water can also become dangerously cold when it gets deeper."
The Council is also asking people to be aware of another summer time hazard - the potential for damaging fires being caused by countryside barbecues.
People are asked only to use purpose-manufactured barbecues, always to keep a bucket of water handy and to be particularly careful of where they site a barbecue.
In case of emergency call 999 immediately.
