The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Trestrignel over the next couple of weeks.
Honestly, I’ve gotta be straight with you – this is a tough stretch. The entire 16-day window is a bit of a write-off for quality surf. We’re stuck in a pattern of poor conditions, with cross-shore and cross-onshore winds spoiling most sessions. The water is sitting at 67°, which is a touch warmer than usual for this time of year, but that’s about the only nice thing I can say.
There’s a long gap at the start with no decent recommendations. The first real glimmer of hope comes right at the end. On Sunday morning, the 6th of September, we finally see a window of opportunity. The wind is glassy, swinging from the WSW at just 3 mph, which is a major positive – it’ll be clean. The swell is small at 4ft from the west, with a period of 9 seconds, and the combined energy is weak at 271. It’s surfable, but very ordinary. It’s the only standout, and it’s more of a gentle paddle than a proper session.
Before that, the biggest swell arrives around Saturday the 29th of August, with swell heights hitting 8ft from the WSW, but the wind is a strong 28 mph cross-shore, making it a messy, lumpy mess. That’s a kite-surfing setup, not a paddle-surfing one. The energy peaks at 717 (moderate), but it’s just not worth it for a surfer.
After that Sunday morning window, things go straight back to being poor. The winds pick up again, and the swell direction stays mostly west and west-northwest, but the wind state never plays ball. The long-range, from the 7th through to the 11th, is a write-off with fresh onshore and cross-shore winds, and the swell energy is moderate at best, but the quality is just not there.
So, to sum it up: if you’re desperate for a paddle, the morning of Sunday the 6th of September is your only real shot. Glassy conditions, clean waves, but small and ordinary. Otherwise, the whole 16-day run is a blank. It’s a poor stretch for Trestrignel, but that’s how it goes sometimes. Forecasts can change, but for now, don’t get your hopes up.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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.
