The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Mawgan Porth over the next couple of weeks.
To be honest, the first week is a bit of a struggle. The wind’s just not playing ball. We’ve got a consistent cross-onshore or onshore breeze messing up the surface, and the swell is pretty weak and messy. You’ll see a few small waves, but nothing that’s worth getting too excited about. It’s a real waiting game here.
The first real glimmer of hope comes on the morning of Wednesday, August 12th. It’s a small one, with swell around 2 ft from the West, but the period stretches out to 10 seconds, giving it a bit more shape. The big news is the wind goes glassy, and the water is clean. Combined swell energy is moderate (104). It’s a beginner-friendly size, but it’s a proper little window of clean, surfable waves in an otherwise messy stretch.
After that, the onshore winds come back, and we’re in a bit of a grovel for the next several days. The models are then hinting at a much bigger pulse arriving towards the end of the second week. Monday morning, August 18th sees a jump to 8 ft from the West, with a 9-second period. That’s a big jump in energy (1064), but the wind is a moderate cross-onshore, so it’s going to be a lumpy, bumpy beast. That’s expert territory only, and even then, it’s not going to be pretty. By the afternoon of the 18th, it peaks at 10 ft from the West with a combined energy of 1509. Again, that’s for the brave and the experienced; the wind is still cross-onshore, so it’s going to be a battle.
The most promising moment in the whole forecast actually lands on the very last day of the outlook. On the morning of Thursday, August 20th, we get a nice 4 ft West swell, with a 9-second period, and the wind shifts to a light cross-offshore and the conditions are described as clean. The combined energy is moderate (268) and the score is the best of the lot. This is the standout. For a river mouth break like Mawgan Porth, that light offshore wind is going to make the lineup look a lot more appealing. It’s a proper clean, shoulder-high option. Crowds are possible here, but with the clean conditions, it’ll be worth the paddle out.
So, in summary: a long, frustrating gap with nothing to write home about, then a couple of big, wind-affected swells for the experts in the third week, and finally a tidy, clean morning on the 20th that looks like the pick of the bunch.
Stay keen.
Rusty.
