The Lowdown
Right then, let’s look at the local stretch, Trestrignel. It’s a sheltered beginner spot, but the next couple of weeks are a rough go. Water temp is about 66°F, which is nearly two degrees warmer than normal for the time of year – you’ll feel that.
For the first ten days, from the 10th through the 20th of August, it’s a long, dry spell. Swell is tiny, mostly 1ft to 3ft, and the wind is constantly onshore or cross-shore, leaving the surface choppy and ugly. The combined swell energy is weak, barely breaking 100 at times, so there’s no punch. You’d be better off staying on the beach.
The only bit of hope in that first stretch is Wednesday morning, the 12th. A light offshore from the SE cleans it up nicely, but you’re still looking at only 2ft of swell with a 10-second period. It’s labelled poor, though – not enough to get excited about.
Things finally turn on Thursday the 20th. The wind goes light cross-off from the SW, and the surf becomes surfable, even if it’s ordinary. Swell bumps up to 4ft from the WNW with a 9-second period, and the combined energy climbs to a moderate 201. It’s nothing special, but it’s the best we’ve seen all week. Then Friday the 21st is your real standout. The morning stays clean with a light cross-off and 3ft of swell. Then the afternoon turns glassy – I mean, dead calm – with a light breeze from the NNW and 3ft of WNW swell with a 10-second period. That Friday afternoon session is the only one worth paddling out for. Small, but clean and fun for the beginners.
After that, from the 22nd through the 25th, it’s back to poor, choppy slop with onshore winds and tiny waves. A couple days see moderate energy (like 353 on the 25th morning) but with strong cross-shore winds from the NE, it’ll be lumpy and blown out. Kite surfers might get a kick, but for a paddle board, it’s a no-go.
Bottom line: aim for that glassy Friday the 21st afternoon. Everything else is a long wait.

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
