Cable Bay (Porth Trecastell) Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s be straight with you: the next 16 days at Cable Bay (Porth Trecastrell) are looking like a write-off. I’ve scanned the charts and there’s just nothing worth paddling out for. We’re looking at a long dry spell for any decent waves.

The whole forecast period is a ghost town for surf. The swell is tiny, mostly 0.3 ft, and when it does try to push past that, the wind is all over the shop. The water temp is sitting at a very unusual 64° – that’s much warmer than normal for this time of year, so you’d be warm, but you’d be floating on a lake.

We start Sunday morning, the 23rd of August, with a tiny 0.3 ft swell from the SW and a cross-offshore breeze. The combined energy is a measly 16 (weak energy). It’s a clean-looking surface, but there’s no push in the water. Monday morning the 24th is glassy, but the swell is still just 0.3 ft. It’s heartbreaking.

The only faint glimmer comes on Thursday the 27th of August, when the afternoon shows a 3 ft swell from the SSW, period 7 seconds, with the combined energy hitting 61 (still weak). The wind is onshore from the SW though, and the surf is described as marginal. This is not a session to get excited about.

Friday the 28th sees the swell bump up to 4 ft, but it’s a short-period, wind-affected mess with a 5-second period and cross-on winds. The energy is 77 (weak). By Saturday the 29th, the swell hits 6 ft from the W with a combined energy of 206 (moderate wave energy), but it’s accompanied by a 22 mph cross-on wind. The wave comment is “poor surf conditions” and it’s lumpy. This is kite-surfing territory, not paddle surfing.

The rest of the run into September is a sad story of tiny, blown-out, or onshore junk. On the 4th of September, the swell tries to get to 4 ft again, but with a 25 mph onshore wind, it’s a no-go.

So, what’s the best on offer? Honestly, there isn’t one. This is a blank run for the area. Cable Bay is an exposed SW spot, and it’s just not getting the love. The forecast confidence is high for the near term because it’s so consistently bad. For a place that’s fairly consistent, this is a rough patch. Don’t hold your breath; forecasts can change, but for now, the board stays in the van.

Rusty.
