The Lowdown
Alright, Rusty here. Let’s look at what’s coming down the line for Mawgan Porth.
To be straight, the next 16 days are a tough stretch. There’s a long, bleak run ahead. There is no period where I’d say, “Drop everything and go.” The wind is almost always a problem—onshore, cross-onshore, or just messy—and the wave quality suffers for it. The setup at Mawgan Porth is a river mouth, and it’ll be pretty uninviting for a paddle surfer for most of this outlook.
There is no standout session in the first week. From Monday the 7th right through to the end of that week, the wind is on it or across it, and the surf is tagged as poor. The water temp is 65°, which is a touch warmer than normal for this time of year—about 4°F above average, so that’s notable if you’re just getting wet, but it won’t help the waves. Monday the 7th has a 7ft west-southwest swell with a 13-second period, but with 16 mph onshore wind, it’s just blown-out junk. The combined swell energy is strong at 1632, but that energy is wasted.
Tuesday the 8th is more of the same: a 6ft west-northwest swell (9-second period) with 16 mph cross-onshore wind. Choppy and lumpy. Wednesday the 9th morning drops to 5ft with a cross-shore wind, still marginal. The energy drops to moderate (331). By Thursday the 10th, the swell bottoms out to 2ft with weak energy (44-58) and cross-onshore wind. Friday the 11th sees a 5ft swell return, but wind is cross-onshore again.
The second week doesn’t get much better. A gap appears from around Saturday the 12th, with small waves and dodgy wind. Sunday the 13th has a 5ft west swell with onshore wind—still poor. Monday the 14th is cross-onshore and choppy with 4ft swell. The best-looking swell of the outlook might be on Tuesday the 15th, with a 6ft west-northwest swell and an 11-second period—the longest of the run—but here’s the kicker: 22 mph onshore winds ruin it. Combined energy is 718, so there’s power, but again, it’s unrideable for a surfer. The swell is over 5ft, so not for beginners, but honestly, it’s more of a kite surf day with that wind and a beach setup.
From Wednesday the 16th onward, the surf steadily fades to knee-shredding mush by Sunday the 21st, with swell down to 1ft. The last few days are just a write-off.
Honestly, this is a blank run. It’s one of those periods where the forecast doesn’t give you a real option. For the area, this kind of dry spell isn’t unheard of. We just have to wait for the next change.
Rusty out.
