Summer is the perfect chance to enjoy the outdoors and cool down in water.

But the differences between swimming inside and swimming outdoors in the sea or a lake means it’s crucial to be aware of how you can stay safe.

Here are 7 tips for staying safe this summer:

1️⃣ Look for signs: Before going in the water anywhere outdoors, ask yourself whether you should be swimming there. Look for warnings or guidance signs which may alert you to dangerous places to swim. If there isn't a safe place to enter and exit the water, look elsewhere to swim.

2️⃣ Don’t expect a solid pool floor: You won’t have a secure, solid pool floor underneath you when swimming outdoors. The bed of a lake, river, or sea will rarely provide a completely solid footing, and there may well be other obstacles and hazards underwater that you cannot see.

3️⃣ Expect a current: Rip currents, waves and tides will move you in different directions in the water. Always check the tidal activity before you go in so you know what to expect. Also, breathe away from waves and keep an eye on the shoreline. You should always swim parallel to the shore in standing-depth water.

4️⃣ Dry off: Make sure you enter the water slowly and safely rather than jumping in. After you've cooled off and your body temperature has reduced, it’s time to get out of the water. Don't stay in cold water once your body is starting to shiver.

5️⃣ Don’t go out on your own: You aren’t allowed to swim in a pool without supervision, so don’t go swimming outdoors without anyone around. The safest and best places to go swimming outdoors will have lifeguards on duty, and you will be much safer swimming with friends and family than on your own.

6️⃣ Stay calm and signal: If you or Tilly do get into difficulty swimming outside, stay calm and signal to shore for help. Fight the instinct to swim harder and against the water.

7️⃣ Dial 999: If you see someone else in trouble in deep or rough water, don't go into the water to help them. Too many people drown trying to save other people or their pets. Instead, call 999 or alert a lifeguard immediately. Look for something that floats that you can throw to them.
