Cable Bay (Porth Trecastell) Surf Forecast and Surf Report

Right then, let’s have a look at what’s on the cards for the next couple of weeks around Cable Bay (Porth Trecastell). I’ll be straight with you – it’s a bit of a tough stretch. The forecast is pretty bleak for a good while, with no real surf to speak of for the first week and a half, and even when something pops up, it’s not looking great. We’ve got a long gap of nothing from the start, and the first real chance of a wave doesn’t come until the tail end of the period.

The water here is sitting at about 63°, which is a touch warmer than normal for this time of year – a bit of a nice surprise, but it won’t make up for the lack of waves.

Right, from the get-go, Wednesday the 22nd through to the end of July, it’s a dead loss. Wednesday morning you’ve got a cloudy sky and a 12 mph north wind blowing cross-offshore, but the swell is a flat zero. Same story for the afternoon, and the rest of that week. Thursday and Friday are clear and sunny, but still no swell – just a whisper of 0.3 ft from the south on Friday, with a period of 13 seconds, but the combined energy is only 3 – that’s practically nothing. You’d be better off having a beach day. Saturday the 25th brings a bit of a pulse – 3 ft from the west-southwest, but with a short, choppy period of just 4 seconds. The wind is onshore and strong, making it messy. The combined energy is a weak 29. Honestly, not worth paddling out.

Sunday the 26th is even worse – 1 ft with a fresh 19 mph cross-onshore wind. It’s lumpy and horrible. Monday and Tuesday continue the story of small, short-period swell with fresh, onshore winds. The combined energy never gets above 54. This is all poor surf.

Now, we start to see a bit of a shift as we head into the end of the month. On Friday the 31st of July, the morning still looks poor, but the afternoon brings a 5 ft swell from the south-southwest, with a period of 6 seconds. The combined energy jumps to 160 – that’s moderate. But the wind is a moderate 12 mph cross-onshore, so it’s going to be choppy. The wave comment is still “poor surf conditions” – it’s not clean.

The first real, albeit marginal, spot comes on Sunday the 2nd of August. The afternoon shows a 6 ft swell from the south-southwest, with a period of 6 seconds, and the combined energy is 209 – that’s moderate energy. The wind is a gentle 9 mph onshore. The wave comment finally says “marginal surf forecast or questionable tide conditions.” This is the best we’ve got in the whole 16 days, and it’s still not a standout. It’s the only time the score crept up to a 1 out of 10. The swell is over 5 ft, so it’s a bit much for beginners, and the onshore wind won’t help. It’s a bit of a messy one, but it’s the only window where you might get a wave.

After that, Monday the 3rd and Tuesday the 4th of August are back to small, choppy, and poor conditions. The rest of the forecast is a washout – tiny swell, strong winds, and nothing to get excited about.

So, the honest truth is there’s no standout session here. The only date that might be worth a look is Sunday the 2nd of August, but go in with low expectations. The break is fairly consistent, but the forecasts just aren’t lining up for it. The surf is poor, and the wind is mostly onshore or cross-onshore, so it’s not going to be clean. For the first 10 days, it’s a solid blank run. It’s a bummer, but it happens. The forecasts can change, so keep an eye on it, but for now, I’d leave the boards in the car.

Rusty.
