Cable Bay (Porth Trecastell) Surf Forecast and Surf Report

Right then, let's have a look at what Cable Bay (Porth Trecastell) has got cooking for us over the next couple of weeks. I'll be straight with you, it's a bit of a tough stretch.

We're kicking off Sunday the 13th with pretty much nothing going on. A tiny 2 ft SW swell with a short, weak 6-second period, and the wind is light but onshore. The water's sitting at 62°, which is a touch warmer than normal for this time of year, but that's about the only highlight. The combined energy is a measly 18 – that's barely a ripple.

Monday the 14th and Tuesday the 15th see a bit more size, with the swell bumping up to around 4 ft to 5 ft from the SSW and WSW, but the period is still a poor 5 seconds. The problem is the wind. It's howling from the south and west at 12 to 22 mph, blowing straight onshore and making a complete mess of it. The energy climbs to a moderate 101 to 109, but it's all chop and no shape. Not worth getting wet for.

We get a bit more push on Thursday the 17th and Friday the 18th, with the swell hitting 5 ft from the WSW and W, period stretching to 6 seconds, and energy in the moderate 138 to 169 range. But again, that wind is a killer. Moderate to fresh cross-onshore breezes keep it lumpy and poor. Friday afternoon does see a brief window of onshore wind, but the swell drops to 4 ft, so it's a no-go.

Now, Saturday the 19th is the first day that gets a sniff of a chance. We've got a 6 ft to 6 ft SW swell with a 6 to 7-second period and a solid 255 to 314 combined energy. The wind eases to a gentle breeze, but it's still cross-onshore and fairly choppy. It's only a marginal call at best. For a spot like Cable Bay that is fairly consistent, this is a frustrating run.

From Sunday the 20th right through to Sunday the 27th, it's a long, bleak gap. Swell drops right off into the tiny stuff, below 3 ft, and for a few days there's literally no swell at all. The wind does go clean, with some glassy conditions and light offshore breezes on the 24th and 27th, but there's simply no wave energy to work with.

The one faint glimmer in this whole outlook lands on the 22nd and 23rd of September. On Tuesday the 22nd, we get a 4 ft WSW swell, period 6 seconds, and 120 combined energy, with a moderate cross-offshore breeze. The guidance says clean, which is a big positive. Then Wednesday the 23rd is the standout. The swell builds to 7 ft from the NW, with a 6-second period and strong energy of 308. The wind is a moderate cross-offshore, and the guidance is calling it clean. Now, 7 ft is getting up there, probably better for the more experienced crew, and with a short period it'll be a bit crumbly, but if you're an intermediate or above, that Wednesday morning and afternoon is your best shot by a mile. It's the only real stand out in the whole two weeks.

To be honest, for most of this period, the setup is so blown out and weak that a kitesurfer would have a better time of it than a paddle surfer.

So there you have it. A long, quiet spell with one clean, punchy day on the 23rd to keep hope alive. The forecasts can always change, so keep an eye on it.

Rusty.
