The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one. We’ve got a 16-day window for Mawgan Porth, and I’m looking at a lot of flat, choppy, and wind-scrambled water. The forecast is pretty grim, so temper your expectations.
From now through the rest of July, the story is mostly the same: small, weak swell with a lot of wind on it. The water temp is sitting at 64° right now, which is a touch warmer than normal for the time of year, so at least you won’t freeze while you’re waiting for a wave. The combined energy is mostly two-digit values, well under 100, meaning the ocean is just not packing any punch.
We don’t see any real surfable waves until the morning of July 21st. That Tuesday morning offers a tiny 3ft swell from the NNW, but the wind is a light cross-off from the NE, so it’ll be clean. The energy is still weak at 74, and it’s just a one-star kind of session – surfable, but very ordinary. Nothing to get excited about.
The next tiny glimmer is much later, on the morning of July 28th. We get a 3ft swell from the W, and the wind goes glassy – that’s a major positive. The energy is a bit better at 120, getting into that moderate range. It’s still a one-star day, but that glassy morning is your best chance for a clean, small wave. The swell direction (W) is a good match for the optimum WNW, so the shape should be okay.
After that, the last week of July and into early August is a mess of onshore winds and building but messy swell. On July 29th, we see a 5ft swell from the W, but with a fresh 19 mph cross-on wind, it’s going to be lumpy and poor. The energy jumps to 192, but the wind kills it. For the experts, it might be worth a look, but for everyone else, stay home.
Honestly, if you’re itching for anything, the glassy morning on July 28th is the standout. It’s not big, it’s not powerful, but it’ll be the cleanest wave in the whole window. The rest of the period is a write-off for a decent paddle. This blank run looks pretty normal for the area given the conditions.
Rusty.
