RNLI issues warning as large swell forecast to hit South West
The RNLI say there is a risk waves could catch walkers out and sweep them off their feet into the sea

The RNLI is warning those in coastal areas of the south west to take care and stay aware from beaches ahead of a swell forecast to arrive on Friday (January 30).
According to Steve Instance, RNLI Water Safety Lead for the south west, waves between 10 to 15 feet are being predicted on Friday, which, although not unusual for this time of year, come with heightened risks due to the swell period (long lull) between waves.
Surf forecasts are identifying a 17-second swell period, which means extended lulls between sets of powerful waves and unpredictable surges that could suddenly travel up to 300 metres along beaches and harbour walls
These conditions are particularly dangerous close to the high tide expected in the middle of the day.
The RNLI say there is a risk this could catch walkers out and potentially sweep them off their feet into the sea.
Steve Instance said:
"We’ve seen so many times how easy it is to get caught out by the sea, and we know that nearly half of people who die at the coast never intend to go into the water.
"Our advice is to keep well away from what will be wet and slippery cliff edges, sea fronts and beaches on Friday.
"If you do plan to visit the coast or a waterside location, we urge you stay a safe distance from the water as conditions could knock you off your feet or wash you into the sea, let someone know where you are going and carry a means of calling for help.
'If you find yourself in trouble in the water, remember to Float to Live: lie back in the water with your head so far back that your ears are submerged, extend your arms and legs and try to relax as best as you can until you get control of your breathing. If you see someone else in danger in the water, call 999 or 112 and ask for the Coastguard.
"If you have something that floats that they can hold on to, throw it to them. Don’t go in the water yourself – you could end up in difficulty too."
The RNLI is urging people to take precautions and be vigilant if visiting the coast on Friday.
