Unless you know the areas you’re swimming very well we’d always recommend a local guide…I appreciate that we are a local guide and it’s obviously in our interest but…it should always be safety first. If you get together as a group, the water safety can be very affordable and it’s always good to have someone with you that knows the local area and is familiar with the conditions.
Generally and if you’re swimming in areas without swell, the shallower the better. Again, without swell it’s generally better to swim on neap tides and on an incoming tide. Ideally on a slack tide (ie. 20 minutes either side of high/low tide. That’s because there is less water movement around these times…but be careful you don’t stay in too long after high, as the water will then start to flow out quite quickly.
WHERE TO START : ideally you’d choose two areas. Both facing opposite directions. That way, if there’s a strong onshore wind and chop on one coast, you can move across to the other. We often base ourselves in Penzance and the Lizard Peninsula for that exact reason. In an ideal world you’d have a light off-shore breeze.
If you’re planning a series of swims your best bet is to find a central parking location and park up early. You could then potentially walk or cycle to multiple swim locations.
THE SWIMS : try and pick swims with multiple exit points. Have a plan B. If there is water movement and you can’t get in you’ll already have an exit point. This will potentially avoid panic, which typically leads to silly decisions…
HELP : inform the RNLI/coastguard/local lifeguards of your plans. Give details regarding timings, swim locations and numbers. Also, look up local businesses. If you’re quite remote and don’t have phone r3ception, they might. Taking a mobile, VHF radio or rescue beacon is always a good idea.
VISIBILTY : just the usual. Take a bright swimming cap, tow float etc.
ADDITIONAL SAFETY : do a head count in and out. You could also take emergency contact info and med records for everyone.
RESCUE EQUIPMENT : something like a SUP could be ideal. It’s not specifically designed for rescues but can cover distances quicker than swimming and can be used for buoyancy, should anyone get in any trouble. Visibly they’re also far easier to find in the sea. The group could take it in turns and an inflatable SUP are quit3 easy to transport.
