GUIDE TO 2024

We still have a couple of events in the pipeline, so this may not be a complete list…depending on when you’re reading this. We also offer shorter notice swims (based on the tides) throughout the year and will often create small group swims around individual bookings.

MAY 25 - starting in slightly cooler water but the weather has been great in May for the last few years and these are shorter swims…so water temp isn’t a problem. This is a shorter distance ‘slow swimming day out’, multi-swim (non)-event. Number currently restricted to 24 and some head-up breaststroke is expected…encouraged even! These are leisurely swims, on a social day out. West Cornwall is our back yard and we know it better than any other area in Cornwall. Loads of opportunity for great beach swims. Previous footage - CLICK HERE. TICKETS / MORE INFO - CLICK HERE.

JUNE 8 - a little adventure in north Cornwall. The North Cornwall 5K Day. Quite simply, open to anyone that can swim….5k (not in one go)! All abilities welcome, provided you can cover the distance over 3 swims. So approx 1.7km per swim (x3). We have a delightful back-up plan in case of swell or undesirable wind. Limited number on the event, avoiding mass starts and tight turns around buoys… MORE INFO - CLICK HERE

JUNE 18-20 - a ‘slow swimming’ midweek holiday based around west Cornwall, the Lizard and Helford. As there is a huge area to choose swims from, this holiday can offer some absolute beauties! We have suggested a centrally located campsite but you can stay where you like. We have multiple members of staff on safety on these holidays, so pace and distance is very flexible. Loads of potential for a mix of beach and river swims. Previous footage - CLICK HERE. MORE INFO - CLICK HERE

JUNE 25-27 - our standard pace midweek, west Cornwall holiday. By standard pace you’d be looking at the middle lane of a public swimming session (from fastest to slowest)…provided you can cover the distance we really aren’t that bothered. This holiday offers longer distances, of around 1.5-2km per swim. We have ample team members on water safety and we can split the group, if needs be. Again, we know west Cornwall very well. Great potential for lots of beach swims. Previous footage - CLICK HERE. More info - CLICK HERE.

JUNE 29 - Our 10K Day swimming event. 4 swims, over 1 day, totalling 10km. This event will be based in the St Mawes - Roseland area. Numbers on this event are limited to 50. Although some are welcome to race the routes, it is really more of a challenge, than an event. We’ve stripped back the t-shirts and freebees normally associated with this sort of event and simply kept the price down. Great opportunity for beach and river swims. Previous footage - CLICK HERE. More info - CLICK HERE.

JULY 2-4 - slow swimming midweek holiday, based around the Penzance area. Like the other slow swim holidays, we’ll pick nice flat and safe routes over a shorter distance (250m -1km). We’ll try and keep this one centred around Penzance, if the conditions allow. Some amazing beaches in the area for fantastic swims. Previous footage - CLICK HERE. More info - CLICK HERE.

JULY 5-7 - Standard weekend swimming holiday, based in St Ives / Penzance. By standard pace you’d be looking at the middle lane of a public swimming session (from fastest to slowest)…provided you can cover the distance we really aren’t that bothered. This holiday offers longer distances, of around 1.5-2km per swim. We’ll try to include some delightful swims, in the St Ives area…as well as some around Penzance. All swims will be launching from beautiful beaches. Previous footage - CLICK HERE. More info - CLICK HERE.

JULY 12-14 - slow-to-medium pace swimming holiday, in St Austell. This is a flexible speed/distance holiday that allows the participants to explore St Austell Bay. Swimmers have to be able to cover around 500m per swim at their own pace. We’ll have multiple personnel on water safety, so we can subdivide into smaller groups. Previous footage - CLICK HERE. More info - CLICK HERE.

JULY - AUG - we have a selection of one-off swims throughout July and Aug (pace requirements included on the link)…as well as additional dates to come. CLICK HERE for calendar.

SEPT 6-8 - easily one of our most popular weekend swimming holidays. We restrict numbers (15) on this one and it’s a slightly more intimate holiday. The Lizard Peninsula has dozens of fabulous swims on offer, including both beach and river options and the water is a great temp this time of year. Previous footage - CLICK HERE. More info - CLICK HERE.

SEPT 27-29 - Our most affordable swimming holiday. Set on the weekend, in the St Mawes / Roseland area. At the end of Sept the water is nice and warm. The holiday is set in an area that offers great protection from the wind and you have dozen and dozens of river and sea swimming options. Previous footage - CLICK HERE. More info - CLICK HERE.

READING THE CONDITIONS / PLANNING A SWIM

There is an art to reading the conditions and planning a swim. It really isn’t a difficult art to pick up though. The longer you look at the conditions and get used to planning, the better you tend to get at predicting the conditions.

Below, we’ll look at a specific swim and then how you’d go about checking the conditions and planning a route or possibly finding an alternative swim.

So we’re looking at Penzance sea front / Penzance Promenade. As you can see, by my dodgy scribbles - with a south, southwest or southeast wind, the wind (and chop) will be blowing straight in there. A wind strength of 0-10 kmph won’t produce a great deal of chop. 10-20 kmph will produce a little. 20km+ will start producing enough ‘chop’ to make the swim far more challenging and far less pleasurable. You also need to consider the state of the tide. At high tide the water level is half way up the sea wall. If chop and swell hits the wall it’ll bounce off and send that chop back out to sea. So…if you were swimming at high tide you’d be hit by chop from a few different directions.

START PLANNING when looking at where to swim you should always start the plan at home on the internet. There are a number of different resources that you can use. We like ‘Tides4fishing’, there is also Windfinder, Magic Seaweed (soon to have a name change), Windy App, Nautide, local to Cornwall is the free My Coast App (I think they’re starting to roll this out nationwide). When looking at these resources you should be checking the wind direction and strength, tide times, swell, you can also look at the weather forecast (avoiding any storms/predicted lightning/drastic wind changes…). Below, we’ll use the Tides4Fishing website.

In our example at Penzance sea front, we’re looking at a 10am swim. The wind will be Northerly, at 31 kmph. So, whilst that is a little strong, it’s off-shore for a south facing swim. That means that the wind has no opportunity to influence the conditions, in terms of chop, as the wind only hits the water on the shoreline. You may think that this wind would push you out to sea…if you swim front crawl, there’s a tiny surface area exposed to the wind. This will have minimal impact on the swimmer. If you swam head-up breaststroke and you weren’t such a strong swimmer, you have more surface area exposed to the wind. This may make it trickier to swim back to shore. In this instance, you could plan a high tide swim…so that the harbour wall offers protection from the wind and the off-shore wind blows straight over your head. Next we’ll look at swell. Swell isn’t so much a factor in Penzance (sometimes local knowledge is crucial).

Again, in our example the swell for 10am is around 1.8m. You don’t really get breaking waves in our Penzance example. So whilst this is a decent size swell, breaking waves aren’t a factor. If we go back to the wind direction, we know that it’s 31 kmph from the north. So that wind will be pushing against any swell and flattening it right out. If it were 31 kmph from the south, with a 1.8m swell it’d be a very different story. Anyway, with a strong offshore wind and 1.8m swell there isn’t going to be too much to worry about. The only slight issue you might have is getting in off the slipway at hight tide. There may be a little bit of water sloshing around. *At this stage I will point out that the swell section of the website is my least favourite and least accurate. I’ll always double check the swell with Surfline.com. I’ll pick a nearby beach, that faces the same direction…like Praa Sands or Perranuthnoe and check the surf prediction. This will give you a good indication of the swell size.

Lastly, we’re looking at the tide. At 10am, it’s around a 1.9m tide. Bear in mind that tidal ranges can have massive differences from area-to-area, around the country. You need to specifically look at the area where you’re planning to swim, for accurate tide times and an idea of the tidal range. The ‘tidal coefficient’ is a great feature and gives you a visual representation of exactly how much water is moving around. In our example, it’s 75/120. So it’s not a huge tide but it’s not a small one either. A 120/120 is the biggest possible tide you could experience and a 0/120 would be the smallest. Above, it also gives you a text description of the tidal movement…’a high value and therefore the range of tides and currents will also be high’.

Back to the example swim, a 1.8m tide would make it tricky to get in along Penzance promenade, as it’s quite rocky. You’d have to head for the beach towards Newlyn or swim off the Battery Rocks area, at the back of the Jubilee Pool. If you were the head-up breaststroker we spoke about earlier and were worried about the wind you might wait for the afternoon high tide and get protection from the sea wall along the promenade.

OTHER FACTORS :

• land mass. You often get large tidal movements through narrow land masses. You can get this with long narrow beaches or area like Dover. You have water funnelling through narrow gaps or land masses and can get strong currents on an outgoing tide or almost constant lateral currents, as the tide goes in and out.

• tides. You have the most water movement in the middle two hours between a high and low tide. These are hours you can avoid. Particularly if you’re experiencing spring tides. If unsure of an area normally best to ‘test’ on an incoming tide, avoiding those middle two hours.

• headland. You can experience currents moving around headland and islands, particularly when there’s deep water in these areas. Remember that most people would struggle to make any forward movement against a current as small as 2 knots!

BE FLEXIBLE WITH SWIM LOCATION

Our example location was Penzance sea front. If we look at Carbis Bay (10-15 minute drive away) on the same day. The wind would blow straight in here. It’d really be whipping up some chop and wouldn’t be the most pleasant location to swim in. The swell is coming from the south so you wouldn’t have surf but you would have constant lumpy chop and plenty of it.

ADDITIONAL CHECKS

You can always make additional checks if your swim location has a webcam. Just remember that most webcams are wide angle and aren’t always that close to the water. So any chop or swell may look a little smaller than it actually is.

FINALLY

You can do all the checks in the world at home…but it’s really important to re-check the conditions when you arrive. Ensure that the conditions are behaving in the way you’d expect. Be prepared not to enter the water and possibly have a plan B…just in case.

COURSES

Sea Swim Cornwall have set up an affordable course to teach the fundamentals of planning your swim and understanding the conditions and rip currents. Our ‘First aid for swimmers’ course is available in a number of locations throughout the summer. CLICK HERE for more info.

Polurrian Swimming

Polurrian Beach is a real stunner on the Lizard Peninsula. It has limited parking or you park up at Poldhu and walk a good mile on the coast path. Whilst this might put some people off, it ensures the beach is never that busy.

Now, the beach can pick up swell. So you have been warned. Typically, not a lot of swell over the summer months and at the time of writing, it is lifeguarded over the 6 peak weeks of the summer. You’d generally want to avoid swell or wind of any strength from the west. I’d also be very careful swimming there, particularly near the headlands on an outgoing tide, particularly a spring tide.

Plan your own salt water wild swimming trip

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.
