The Lowdown
Right, folks, Rusty here. Let’s take a real honest look at what’s coming down the line for Trestrignel. There’s a stretch of pretty grim conditions ahead, so I’m not going to sugar-coat it for you.
The story for the next week and a half is mostly a tough one. We’ve got a lot of onshore and cross-onshore winds, and the surf quality is just not there. The water temp is sitting at 65°, which is a touch warmer than normal, but that’s about the only thing that’s mildly pleasant.
The first real blip of interest comes on Thursday, September 10th. It’s a small morning window with a 2ft swell from the WNW, period of 9 seconds, and light cross-offshore winds from the SSW. The combined energy is weak at 111, so it’s not going to be big, but it’ll be clean. That’s the best you’ll see for a while, but it’s still just small, ordinary waves.
The next potential window is Tuesday, September 15th. The morning shows a 2ft swell from the W, period of 8 seconds, but with a clean offshore wind from the S at 12 mph. The energy is still weak at 115, but the offshore wind will make it look better than it is. It’s a tiny window again.
Then we’ve got a long gap of poor conditions – strong onshore winds, choppy seas, and small, messy swell. The wind is relentless.
The only other small chance is Friday, September 18th in the morning. A 4ft swell from the WNW, 9-second period, with light cross-offshore winds from the ESE. The energy is moderate at 305, but it’s a single session before the wind shifts again.
And then, believe it or not, the most promising long-range glimmer is Monday, September 21st. This is a classic case of "looks good on paper, but the wind will ruin it." We’ve got a very long period groundswell of 17 seconds from the WNW, with a solid 4ft height. The combined energy is a huge 1116, so there’s plenty of power. But the wind is a strong cross-onshore from the WNW at 28 mph, with rain showers. This creates a messy, blown-out surface. For an expert, there might be a rogue barrel in there, but for everyone else, it’s a write-off. The long period will make the waves suck hard and close out on the beach, so it’s really a reef or point setup kind of wave, but Trestrignel is a sheltered beach break, so it won’t hold that shape.
Bottom line: There’s no standout session here. The best of a bad bunch is the morning of Thursday, September 10th, and maybe the Tuesday, September 15th morning. Both are small, clean, and only for beginners. Everything else is a fight against the wind.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Trestrignel may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
