Cable Bay (Porth Trecastell) Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s be straight with you: the next couple of weeks at Cable Bay (Porth Trecastell) are looking pretty grim for anyone wanting to paddle out and actually catch something. We’ve got a whole lot of nothing on offer for the start of this stretch, and I mean a whole lot.

We’re looking at a solid run of poor surf through the coming week and into the next. The swell is mostly tiny, weak, and coming from the wrong direction for this spot. The wave energy is barely registering, mostly two-digit numbers like 48 or 74, which just tells you there’s nothing behind those waves at all. There are some clean, glassy moments early on the morning of Friday the 21st, with a slight air and a glassy surface, but the swell is only 0.7ft. You could paddle out on a log and not get wet. It’s frustrating, but that’s the way it is.

We will see a bit more energy kick in around Tuesday the 25th, with the swell pushing up to 5ft. The energy jumps to around 105, but it’s still cross-onshore, choppy, and basically unsurfable. The wind is going to mess it up. That pattern holds for a few days – a bit of size, but with the wind all over it, so it’s a mess.

Now, if you’re looking for something that *might* be worth a look, you’ve got to wait until Saturday the 29th or Sunday the 30th. Saturday sees the swell jump to 7ft with the energy jumping to 352 (moderate wave energy), but again, the wind is cross-onshore and it’s going to be choppy. Not great. Then on Sunday the 30th, there’s a brief moment where the wind dies down a bit to a light breeze. The swell is still around 4ft, and the energy is at 107. It’s still cross-onshore and there’ll be some small wind ripples, but it’s the first time the conditions aren’t a total write-off. It’s a marginal call though, so don’t get too excited.

The real, and I mean the *only* standout in this whole 16-day window, looks like it’s on Monday the 31st. The swell is up to 8ft, and the wave energy is cranking – we’re talking 712 to 824 (strong to very strong wave energy). That’s a proper pulse of west-southwest swell. The problem is, it’s still cross-onshore, so it’s going to be a bit of a battle. This size is pushing past what I’d call beginner territory, and with that wind, it’ll be one for the experienced crew only. It’s a "promising but less certain" call this far out, but it’s the only time we see any real power in the water.

The first week of September doesn’t offer much to get excited about either. A bit of size but the wind stays on it, keeping things messy.

So, bottom line? For the next couple of weeks, Cable Bay isn't your friend. If you're desperate, you might get a session in on that Sunday the 30th, but you’ll be scratching around. If you’re experienced and don’t mind a battle, keep an eye on the 31st. Otherwise, keep the board in the car and wait for a change in the forecast. This long blank run is just how it goes around here sometimes.

Rusty, out.
