The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Trestrignel over the next couple of weeks.
Straight up, this is a tough forecast. For a spot that’s fairly consistent and sheltered from the NW, the wind is going to be the enemy almost the entire time. The first few days are a write-off; we’ve got a decent swell building on the 5th, but the wind is all wrong. Saturday morning on the 5th is actually the only real standout in the whole run, and it’s a short window.
That Saturday morning, the 5th of September, is your clear best bet. We’ve got a 6ft swell coming from the WNW, with a 12-second period, generating moderate wave energy (797). The air is glass, with a light N wind at 3 mph. That’s going to make for clean, lined-up waves. Perfect for beginners, as it’s not too big, but with enough push to have fun. The water temp is about average for this time of year. The downside? Crowds are always a factor here, so get in early.
After that, it’s a grim stretch. From Saturday afternoon the 5th through to Thursday the 18th, it’s a long, painful run of poor surf conditions. The wind swings onshore, cross-onshore, or just messy, and the swell gets chopped up. There’s a period around the 7th and 8th where the swell gets up to 7ft with a 14-second period, but with 12-19 mph cross-onshore winds, it’s just a lumpy, blown-out mess. That kind of size and wind is only for the hardcore, and even then, it’s not worth it. For a sheltered spot like this, that onshore wind kills it.
The only glimmer comes on Friday the 18th and Saturday the 19th. We get a morning glass-off on the 18th with a 4ft swell from the ENE, but the period is a short 5 seconds, so it’s weak and crumbly. On the 19th, we get a cleaner, cross-offshore wind with a 5ft swell from the ENE, but again, it’s a short 6-second period. It’s surfable, but ordinary. Don’t get your hopes up.
So, the honest truth: Saturday morning the 5th is the one to go for. The rest of the 16-day window is a near-total blank. It’s a classic case of an area that can simply go quiet for a stretch when the wind gods aren’t playing ball.
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.
