The Lowdown
Alright, let’s have a look at what’s on the cards for our stretch of coast. Honestly, I’ve got to be straight with you – it’s a tough run. This isn’t a classic setup for us, and the finder’s not throwing up any bold recommendations. For the first several days, we’re looking at mostly poor surf conditions with a lot of wind messing things up. The swell shows up at times, but the wind direction is just not playing ball. We’ve got a gap right through the end of August and into the start of September where the scores are flat – there’s simply nothing worth shouting about until we get to Wednesday the 2nd of September.
Now, Wednesday morning on the 2nd of September is where things finally get a little interesting. The water’s sitting at about average for the time of year, nothing too unusual. The swell is small, around 3 ft, coming from the west, with a short period of 6 seconds, so it’s weak energy (80). The real standout here is the wind – it’s glassy, a slight air from the SSW, which is a rare gift in this stretch. The surf is described as surfable but very ordinary, but for a beginner-friendly spot like Mawgan Porth, that glassy clean surface could make even the small stuff fun. Just don’t expect any power or size.
The rest of the forecast is a grind. Most of the time, the wind is onshore or cross-onshore, often strong, and the swell is inconsistent or just too choppy. The 7th of September Monday morning brings a bit more size – 8 ft from the WNW with a period of 8 seconds (695 energy) – but the wind is light cross-onshore, and the conditions are only marginal. That’s really for the experienced crew, and the quality is still a question mark. By the 11th of September, Friday morning, we see an 8 ft swell from the west (9 seconds, 1040 energy) with a clean cross-offshore wind from the NE, but again, it’s flagged as marginal. That’s a big swell for this break, so only experts should even think about it, and the period isn’t long enough to make it a classic groundswell.
Overall, keep your expectations low. This is one of those stretches where the sea just doesn’t want to cooperate. The best bet is that glassy window on Wednesday the 2nd if you’re a beginner or just want to get wet without getting beaten up. For everyone else, it’s a waiting game.
