Barry Dock RNLI has issued safety advice to those visiting Sully Island, after they received their first shout out of the year to the Island.
The call-out came as four people were caught off by the tide earlier this week.
Whilst they were all brought to safety, albeit a little cold, the RNLI has used it as an opportunity to raise how quickly conditions can change around the Island.
For those walking out to Sully Island, the lifesaving charity suggests checking the tides before you go. The causeway can disappear quickly, and once it's covered, you could be cut off for up to six hours.
RNLI volunteers have also warned that whilst the channel between the island and mainland may look calm, as tides rise, water can rush through at speeds of up to 7 knots (around 8mph), which is strong enough to knock someone off their feet, even in shallow waters, and carry you into the Bristol Channel.
Whilst being cut off isn't just inconvenient, without the right clothing or shelter, visitors could quickly become cold and exposed, with trying to swim back being extremely dangerous.
If you're visiting Sully Island, the RNLI says to:
- Check tide times before you set off - they change every day
- Pay attention to the safety signs at the causeway
- Never cross if water is already covering it because even what appears to be shallow water can knock you off your feet
- Take a means of calling for help
If you do get into difficulty Call 999 or 112 and ask for the Coastguard
