The Lowdown
Alright folks, Rusty here. Let’s talk about the surf ahead for Mawgan Porth.
Well, it’s a bit of a tough slog to start. The next week and a half is mostly a write-off, to be honest. We’ve got a solid run of poor surf conditions stretching from now until the end of the month. The first few days have some decent size, with swell heights around 6ft to 7ft on Sunday the 26th and Monday the 27th, coming from the WNW, but the wind is a real issue. A fresh 22 mph cross-onshore breeze on Sunday is going to chop it up badly, and the combined energy of 482 is moderate, but it’s all for nothing with that wind. The period is short at 7-8 seconds, so it’s just messy.
Things don’t really improve. The winds stay cross-on or onshore for most of the next week, with the swell dropping to under 3ft. There’s a brief moment on Wednesday morning the 29th with a light cross-off breeze and clean conditions, but the swell is tiny at 2ft with weak energy (51) – not enough to get excited about. By Friday the 31st, we get a brief glassy moment in the afternoon with 2ft of swell, but again, it’s just too small.
The first real glimpse of something surfable comes on Sunday the 2nd of August. The morning shows a 4ft swell from the WSW with a light 6 mph cross-off breeze, making it clean. The combined energy is moderate at 186. It’s only rated as surfable but very ordinary, so it’s not a standout, just the best of a bad bunch.
The standout for the whole forecast window actually falls on Saturday the 8th of August. That morning, we’ve got a 4ft swell from the west, with a clean 6 mph cross-off breeze from the NNE. The period is a moderate 8 seconds, and the combined energy is 145. It’s a clean, surfable morning where you’ll actually get a few rides without the wind ruining it. It’s not huge, but it’s the cleanest, most reliable window we’ve got.
Then, on Sunday the 9th of August, the morning turns glassy with a 3ft swell from the west. The energy is moderate at 186, and the period is 9 seconds. It’s another clean, surfable option, but it’s very small.
Overall, this is a long, quiet period. We’ve got a gap of nearly a week with no real surf in the first part, and then just a few clean but small windows. The best bet is definitely the morning of the 8th of August. For a river break like Mawgan Porth, which is fairly consistent and exposed to the WNW, the long period swells (9-10 seconds) we see later in the window are actually fine – they’ll wrap in nicely. Just don’t expect anything big or powerful.
Keep your eyes on the forecasts, though. It tends not to stay this poor for long.
Rusty.
