The Lowdown
Alright, Rusty here, checking in on the stretch ahead. Let's be straight with you – it's a tough run. The only spot in the forecast that ever gets a look-in is Whistling Sands (Porth Oer). It’s a sheltered, beginner-friendly cove, but it’s also inconsistent, and right now it's just not firing. We're looking at a long, dry spell with no real surf to get excited about for the next week and a half.
For the first week, from Friday the 11th right through to the end of next week, the story is the same: small, weak, and poor. Friday the 11th has some knee-high 2.6ft SW swell, but it's weak with low energy (67) and a short 7-second period, plus a stiff 16 mph NW onshore wind. Not worth paddling out. Saturday the 12th sees a jump in size to 6.9ft-7.2ft from the SW, with moderate energy (361-423), but that's all cross-shore wind and messy cross-chop. It's big enough to be too much for beginners, but the quality is so bad it's not good for anyone. Honestly, with that much wind and chop, that setup looks more interesting for kite surfing than paddle surfing. Sunday the 13th drops right back down to ankle-snatchers with a bit of offshore wind, but it’s still weak.
There’s a real gap here. From Monday the 14th through to Thursday the 24th, the forecast is littered with zeros for surf quality. There's a tiny blip on Saturday the 19th of September with a 5.2ft SW swell showing moderate energy (193) and clean, cross-offshore winds, but the rating is still terrible. That's the closest we get to "surfable waves but very ordinary conditions" for the entire run.
The only real change comes way out in the second week, around Wednesday the 23rd of September, but it’s a joke. We get a tiny 0.3ft swell from the W with a very long period of 15 seconds, but it's buried under near gale-force SSE winds at 34 mph. That's clean, but there’s nothing to ride. A 0.3ft wave with a long period is just a long wait for nothing. The energy is so low (8) it’s barely a ripple. The water temp is sitting at 62°F, which is a touch warmer than normal for this time of year.
Bottom line: it's a blank run. The area is known for being inconsistent, so this kind of quiet stretch isn't a total shock. Forecasts can change, but right now, there's nothing to chase.
