Cable Bay (Porth Trecastell) Surf Forecast and Surf Report

Alright folks, it’s Rusty here. Let’s be straight with you – this outlook for the next 16 days is a tough one. We’ve got a long stretch of poor conditions ahead, so don’t be getting your hopes up too high.

Looking at the whole picture, there’s a significant gap with no real surf on offer. For the first several days, from Saturday the 25th right through to the tail end of the month, the swell is tiny, onshore winds are in the way, and the scores are bottom of the barrel. We’re seeing weak, short-period windswell with a combined energy barely reaching 99 (moderate at best, but mostly low double-digit values), so it’s going to be bumpy and messy. There’s a real dry spell from the 25th to the 29th of July, with nothing rideable.

Things start to look a little cleaner by Thursday the 30th of July, but the swell is still minimal. The standout spot, and really the only name in the game here, is Cable Bay (Porth Trecastell). The water temperature is sitting at 62°, which is a touch warmer than normal for this time of year – a small comfort, but not much else.

The best we’ve got is a couple of days around the 30th and 31st of July. On Thursday morning, the 30th, we’ll see a 3 ft, 4-second swell from the WNW with a light NNW cross-offshore breeze. That’s clean, but it’s barely a ripple in terms of energy (29). The waves will be small and weak. Friday morning the 31st is similar – 1 ft from the SW with a moderate N cross-offshore wind, keeping it clean but tiny. The combined energy is only 5, so you’ll be waiting for the occasional knee-high bump.

The confidence in the near-term is low because the swell just isn’t there. Looking further out, we get a glimmer of something on the 3rd of August. Monday morning the 3rd has a 0.3 ft, 8-second swell from the SW with a light offshore from the NE. The period is a bit longer, suggesting a cleaner wave, but it’s a whisper. Combined energy of just 5. Tuesday the 4th of August has a slightly better 1 ft swell from the SW, with a moderate NE offshore wind. The energy is still weak (15), but it’s the cleanest we’ll see. The long period (8 seconds) is a positive, but it’s so small it’s only for the most patient.

The 7th and 8th of August show a brief spike in period with a 12-second groundswell from the S, but it’s only 0.3 ft with a strong onshore wind – that’s just noise, not a wave. The energy is a paltry 4.

The bottom line? There are no standouts here. This is a classic blank run for the area. If you have to paddle, Thursday the 30th and Friday the 31st of July are your cleanest options, but bring a log. The 3rd and 4th of August offer the best chance of something with a little shape, but it’s a long-range call and very uncertain. For now, it’s best to wait for the forecasts to change.

Rusty.
