The Lowdown
Right then, folks, Rusty here. I’ve had a good look at the charts for Trestrignel, and I’ll be honest with you, it’s a grim picture for the next two weeks. We’re looking at a real flat spell with nothing on offer that’s worth paddling out for.
We kick off on Friday, 28 August, with tiny, weak swell. The water’s a touch warmer than normal for the time of year at 67°, but that’s about the only good news. The wind is howling from the WSW at 12-19 mph, putting a nasty cross-chop on the surface. The combined swell energy is a weak 102, and it just looks messy. That sets the tone for the whole outlook.
Through the end of August and into the first week of September, we see some bigger numbers on the swell height, but the wind is a constant problem. Saturday the 29th sees the swell jump to 5.2 ft in the morning and a daunting 9.8 ft in the afternoon with a strong breeze, but it’s all cross-shore and messy. The wave comment for the entire 16-day window consistently says “poor surf conditions.” There isn't a single period where the score out of 10 is anything but zero. Even when the wind is listed as "cross-off" or "clean," like on the morning of 29 August, there’s just nothing rideable. The energy spikes up to 1412 on the 29th afternoon, but with 28 mph winds, that’s a washing machine, not a surf.
Further out, around 4 and 5 September, we get a long-period groundswell of 13 seconds pushing 6.6 ft, which would normally get the heart racing. The combined energy hits a whopping 1588. But again, the wind is a strong cross-shore or cross-onshore at 19-22 mph, ruining any potential. This swell is coming from WNW, which for a sheltered break like Trestrignel that wants NW, isn't ideal anyway, and the wind just kills it.
For the second week, the story doesn’t change. There's a bit of energy around 10 September with 7.9 ft swell, but the wind cranks up again to 22-28 mph from the WSW. It's the same sad story for the whole run. Honestly, for a sheltered spot that’s already a beginner-friendly wave, this is a proper blank run.
It doesn’t tend to stay this poor for long around here, and forecasts can change, but right now? There is nothing to recommend. Don't bother getting the wetsuit wet. If anything, with that much wind and swell, it looks more interesting for kite surfing than paddle surfing.
