Water Safety

The sea can be unpredictable, and even with the temperatures soaring, the fact is that the water is still relatively cool compared to air temperatures.

Just because an area looks safe for swimming it doesn’t mean that it is safe. Only swim in areas that are protected by lifeguards or in areas with which you are familiar. In the case of lifeguard protected beaches only swim between the red and yellow flags.

The RNLI is urging people to Float to Live if they get into trouble in the water. This means leaning back and spreading your arms and legs to stay afloat, controlling your breathing, then calling for help or swimming to safety.

Rip currents are difficult to spot but common on beaches and carry you out to sea quickly. If you do get caught in one, the advice is not to exhaust yourself trying to swim against it. Rather swim parallel to the beach until free of the narrow current and then head for shore”.

Record numbers are also taking to the water on crafts such as paddleboards and kayaks, many for the first time. It is important to always remember to wear a lifejacket or buoyancy aid and to take a means of calling for help.

If you see somebody in trouble on the water or along the coast, or if you think they are in trouble, use marine VHF radio Ch 16 or dial 112 and ask for the COAST GUARD.

Visit Water Safety Ireland & RNLI for more information on how you can stay safe near the water.
