Cable Bay (Porth Trecastell) Surf Forecast and Surf Report

Alright, let’s get this straight. The next couple of weeks are looking pretty bleak for a proper surf. We’ve got a whole lot of nothing on the horizon, with a long stretch of flat, unrideable conditions. But, hold on, there is a flicker of hope right at the very end of the forecast period. It’s going to be a test of patience, that’s for sure.

The wait is the story here. From now through the next several days, we're staring down a blank canvas. Swell heights are barely registering, with the ocean mostly at 0.3ft or even less. The energy is just pathetic, with values often in the single digits, like 10 or even 1. There are a few pulses around the 11th and 12th, but they're weak and messy with onshore winds, so it’s not worth getting excited about.

We’ll see a little bump on the 14th with some 2ft swell and a period of 4 seconds, but it's crossed up. Then the 17th and 18th offer a touch more size—up to 3.3ft—but the wind turns onshore and the energy is still on the low side at 32 and 49. It’s all just poor surf conditions. Honestly, for a spot like this, a run of flat days isn't unusual, but this feels like a longer draught than normal.

Then, as we look to the end of the window, things might finally start to align. From the 20th onwards, we see a pulse of new energy and the winds finally turn favorable. On the 20th and 21st, the swell is pushing 3.6ft to 4.3ft from the WNW with periods hanging around 5 seconds. It’s not going to be epic, but the energy values are climbing, hitting 69 and then 96, which is a healthy kick. The winds turn cross-off and then offshore, which is exactly what we want to hear. The 21st afternoon should finally see some surfable waves, even if they’re ordinary. The water temp is still about average for the time of year, 62.8°F.

Cable Bay (Porth Trecastell) is the only game in town, and this is where the focus should be. It’s exposed to that SW swell, which is what we’re getting. The standout is Friday the 21st. The swell is 4.3ft from the WNW, and with a 9 mph offshore wind from the NE, it's going to be clean and lined up. This is the one to circle on the calendar. The energy value of 96 is by far the most promising we see in the entire period. This is your window. It’s a long way off, so treat it as promising, not guaranteed.

After that, the energy fades again, but there’s a glassy morning on the 22nd and 23rd, though the swell drops right back down. If you can only get out once, make it the 21st afternoon.
