The Lowdown

Alright folks, Rusty here with the long-range look for Trestraou. I’ll be straight with you: the start of this run is going to test your patience. We've got a long, dry spell of tiny, weak swell and poor conditions that's gonna keep the boards in the car for several days. That first real window of opportunity doesn't open up until late in the first week, but there are a couple of days that could make the wait worthwhile.

The water is sitting at a touch warmer than normal for the season at 66°, so at least you won't be freezing while you're waiting.

From Tuesday the 25th right through to the end of August, forget it. Waves are barely on the charts, all under 3ft, coming in with weak energy (18 to 121 units), and the wind is all over the shop. You'll get a few clean mornings with light offshore breezes, but the swell just isn't there to do anything with. It's a total bust.

Things start stirring on Saturday the 29th. A fresh southwesterly kicks up a messy, short-period 6ft swell from the west (energy at 389), but that cross-off wind will make it rough. Sunday the 30th looks a bit better with a 4ft west swell and a solid offshore SW wind in the morning. The combined energy is moderate (187), but the period is short, so it'll be a bit fat and sectiony. Not a standout, but probably the first day you could actually get wet without total frustration.

Now, Monday the 1st of September is one of the real standouts. The morning looks proper fun: a 6ft west swell with a 10-second period, pushing good energy (moderate at 1156). That's a solid, rideable swell size and the wind is a clean offshore from the southwest. Conditions are tipped to be very good. This is your best day for a proper session, no doubt.

Tuesday the 2nd carries the momentum with a solid 8ft west swell, but the early part of the day gets messy with that strong cross-off wind. The afternoon cleans up a touch, but the swell is getting a bit hefty for a beach break, bordering on expert territory.

The real highlight, though, has to be Thursday the 5th of September. We are looking at a southwest wind gusting 28 mph in the morning, blowing strong offshore. That will groom a 6ft WNW groundswell with a 10-second period into absolute perfection. The combined swell energy is strong (591). The comment even notes it’s “strong offshore and clean but hard to paddle into” – that’s the call for solid, experienced surfers. For the crew that can handle the paddle, those waves will be some of the cleanest, best-shaped of the whole outlook. This is the other standout session.

We get a blip of cleaner conditions around the 8th and 9th, with a massive jump in energy (up to 3194 on the 8th!) and big 12ft swells, but those are for experts only, and the wind is mostly cross-off, not ideal.

For a beach break like Trestraou, this is a tough forecast. The two standout days are the morning of the 1st of September and the morning of the 5th of September, but that second one is only for strong paddlers. If the swell hangs in, you might get some fun ones, but the pattern is weak and inconsistent for long stretches. That's just the way this stretch of coast can be.

Rusty, signing off.

Information about the Trestraou Surf forecast

The above surf forecast table for Trestraou provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trestraou can be found by selecting the local surf guide option on the grey menu. Our Trestraou surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Trestraou) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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 Trestraou 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.
