Cable Bay (Porth Trecastell) Surf Forecast and Surf Report

Right then, let's get into it. Honestly, for the next two weeks, it’s a pretty lean stretch here. The swell window is just not cooperating. We’ve got a long period groundswell from the SW rolling in, but it’s barely a whisper at 0.3ft for the first few days. That’s not surf, that’s a ripple. The combined swell energy is pitiful, reading just 8 on Saturday morning, so don't even bother waxing up.

From Saturday the 22nd right through to the middle of the following week, it’s a whole lot of nothing. There are a few glassy moments, like Monday the 24th morning with a dead calm S wind and the water flat as a pancake, but no wave to ride. The water temperature is sitting at 65°, which is much warmer than normal for this time of year, a solid 4° above average, so at least it won't be a cold wait.

We finally see a pulse of life on Thursday the 27th afternoon, with a 7ft SSW swell pushing in. That’s a proper size, but the period is a short 7 seconds and we are looking at a moderate breeze blowing directly onshore from the SSW. That’s going to be a messy, choppy mess. The energy is strong, reading 455, but the conditions will be horrendous for a clean paddle. This is more of a kite-surfing afternoon than anything else for a surfer.

Friday the 28th morning is the only standout, and I mean the *only* real chance in this whole forecast. We get a 6ft SW swell, still a short period at 7 seconds, with a gentle offshore breeze from the SW. The combined energy is high, reading 523, which means there's power in the water. The wind will be right on it from the SW too, so it’s an onshore wind at Cable Bay (Porth Trecastrell). It’s marginal due to tide, but that’s as good as it gets. This is an exposed spot, so it will be breaking, but the onshore wind will make it lumpy. Crowds are sometimes a thing here, but with conditions this average, you might have it to yourself.

From there, the surf dwindles away again into little cross-on junk for the rest of the window. A brief flicker on Wednesday the 2nd of September with a 5ft SW swell and a moderate offshore from the NE, giving us clean 5ft waves with a moderate 182 energy reading. It’s surfable, but very ordinary. The rest is just small, weak, and choppy. A long, quiet outlook, I’m afraid.
