The Lowdown
Right, let’s be straight with you. It’s a bit of a grim stretch ahead for Mawgan Porth. We’ve got a solid run of poor surf stretching right through the coming week, and honestly, it’s not going to be doing anyone any favours. The water is sitting at 64.2°, which is a touch warmer than usual for this time of year, so at least you won’t be freezing while you’re getting battered by the chop.
For the first several days, we’re looking at a mix of cross-onshore and onshore winds, with swell heights pushing 5.6ft to 6.6ft mid-week. The energy is moderate to strong, with the combined swell energy reading between 414 and 946, but it’s all that messy wind that’s killing it. The wave comment says it all – poor surf conditions. All that size and none of the shape. It’s a frustrating kind of swell, all lumpy and blown out. Not one for the log. And frankly, with these conditions, you’d have a better time on a kiteboard than a surfboard.
We finally see a bit of a reprieve on Monday the 21st. The wind swings to a light cross-off, and the swell starts to ease back to 2.3ft to 2.6ft. It’s clean, but it’s weak – combined energy around the 117 to 185 mark. It’s surfable, but very ordinary. You’ll get a few grovellers, but nothing to write home about. Tuesday the 22nd sees a little more size at 3.3ft, still clean with a slight offshore, but again, just very ordinary.
Now, here’s where things get interesting. Keep your eye on Thursday the 24th. The wind goes light cross-off, the sea turns clean, and we’ve got a 3.6ft to 3.9ft W swell pushing through with a period of 11 seconds. It’s not big, but that longer period is going to give it some push. The combined energy is moderate, between 284 and 374. It’s the best on offer, and the only day where I’d say the conditions are genuinely good. Get on it early, because the next couple of days are smaller again.
Friday the 25th is still clean but smaller, running at 2.6ft to 3.0ft with less energy. Then Saturday the 26th morning is glassy with a 3.0ft W swell – clean, but weak, with energy down at 172. Ankle to knee-high stuff for the most part.
The standout of the whole run has to be Tuesday the 29th. We’ve got a 2.6ft to 3.0ft WNW groundswell with a 14-second period, and fresh offshore winds. The energy is moderate, coming in at 266 to 323. That period is long, really long, and it can cause a beach break to close out a bit straight, but if you can find a bank that works, it’ll be clean, lined up, and worth the wait. It’s a promising call, but it’s over a week away, so don’t get too attached to it yet.
Other than that, there’s not a lot else. Monday the 28th has a fresh offshore, but the swell is only 2.6ft with a short 7-second period, so it’ll be weak and gutless. It’s a long stretch of waiting for something decent, but when that offshore wind blows, it’ll be worth it.
