The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the outlook for Mawgan Porth over the next 16 days is a tough one to write. We’re looking at a long stretch of small, weak, and messy conditions, with a lot of north and northwesterly wind just chopping everything up. The water temp is sitting at 64°, which is a touch warmer than normal for this time of year, so at least you won’t be freezing your toes off paddling out for nothing.
The first real chance to even think about a paddle comes on Tuesday morning, 21st July. We’ve got a tiny bit of swell, around 2ft from the NNW, with a short period of 6 seconds and weak energy (67). The wind is a light breeze from the NE, which is actually clean and cross-offshore. The report says "surfable waves but very ordinary conditions," so it’s not a standout, but it’s the first time the wind isn’t ruining it completely. It’s mostly a beginner-friendly size, but the consistency is only fairly consistent, so don’t expect much.
If you’re desperate for something with a bit more push, you’ll have to wait. By Sunday the 27th of July, we see a bigger pulse of swell – 7ft to 7ft from the WNW, with moderate wave energy (397-514). That’s a bit too much for beginners, and it’s only for the more experienced crew. But here’s the catch: the wind is cross-onshore from the NW, and the report says "poor surf conditions" all the way through. It’s going to be lumpy, choppy, and hard to enjoy. The period is only 7-8 seconds, so it’s a short-period wind swell, not a clean groundswell.
Honestly, the only thing that saves this forecast from being a total write-off is that blip on Tuesday morning. After that, it’s a whole lot of nothing until the end of July, and even then, the quality is poor. The wind just doesn’t cooperate for a clean, lined-up wave here. With the swell size and the messy cross-shore conditions, this setup might actually be more interesting for kite surfers than paddle surfers.
So, here’s the best I’ve got: Tuesday morning, 21st July, at Mawgan Porth. It’s your only true standout – and that’s only because it’s the only time the wind is clean and light. The swell is small (2ft, NNW) and the energy is weak (67), but the offshore breeze will make it look better than it should. Crowds are possible, as it’s a spot that can get busy, but on a day like this, you might have it to yourself.
Stay optimistic, folks. The forecast can change, and it tends not to stay this poor for long.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Mawgan Porth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
