The Lowdown
Right then, let’s have a look at what’s on offer for Mawgan Porth.
To be straight with you, the next week and a half is pretty grim. We’ve got a long, dry spell of poor conditions ahead. From Thursday the 3rd all the way through to the morning of Monday the 14th, it’s just not worth paddling out. There’s a real stretch of nothing there, about ten days where the wind is howling onshore, the water is getting chopped up, and the quality is just not there. You’ll see some swell pulses, like a solid 8ft on Monday the 7th with a long 13-second period, but the wind is a fresh cross-onshore, making it a lumpy mess. That kind of energy (1796) is strong, but it’s all blown out.
Now, things finally look to turn around on Monday the 14th. That morning, we get a bit of hope. The wind swings around to a light cross-offshore from the NNE at 9 mph, and it’s clean. The swell is a consistent 5ft from the west with a 10-second period, giving us a moderate energy (347). It’s not a massive day, but after that long wait, it’ll feel like a gift. The water temp is sitting about 64°, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit.
But the real standout, the one I’d circle on your calendar, is Tuesday the 15th. Tuesday morning, we’ve got glassy conditions. The wind is a whisper from the ENE at 3 mph, and it’s dead calm. The swell is a clean 4ft from the west, 9-second period, with moderate energy (285). It’s not a huge swell, but it’s a river break that likes a bit of size, and with glassy conditions, it’ll be absolutely pristine. That is your best bet of the whole outlook. It’s a beginner-friendly spot and fairly consistent when the swell is on, so it’ll be a nice, clean session. Keep in mind, crowds are sometimes an issue here, so get there early.
After that, Wednesday the 16th morning also looks glassy with 3ft waves, but it’s a little smaller. By Thursday the 17th, the wind is back onshore and we’re back to the struggle.
So, to sum it up: you’ve got a long wait, but the morning of Tuesday the 15th at Mawgan Porth is the one to aim for. It’ll be worth the patience.

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
