The Lowdown
Alright, Rusty here. Let's get straight into it for Trestraou.
Honestly, looking at the next couple of weeks, it’s a bit of a slow grind. The swell is small and the winds are messy for the most part. We’ve got a long stretch ahead with very little to get excited about, but there are a couple of little windows where things might clean up. Let's break it down.
The forecast kicks off with nothing doing. Sunday the 9th and Monday the 10th are tiny, with poor surf conditions and cross-shore breezes messing things up. You're looking at a weak 1ft to 2ft of swell with low energy (34 to 82 units). Not worth paddling out.
Tuesday the 11th and Wednesday the 12th aren't any better. The swell stays small, and we’ve got moderate cross-onshore winds chopping things up. The swell direction is all over the place, and the period is short—around 5 to 10 seconds. Just leave the board in the car.
Thursday the 13th shows a little bump in energy, with the swell building to 3ft in the morning and 4ft by the afternoon. The combined energy jumps to 176 and then 271, so there's some push there, but the winds are cross to cross-off, keeping it from being really clean. The morning session on Thursday looks like the first real chance with clean conditions, but it’s still not great.
Friday the 14th and Saturday the 15th are more of the same: 3ft to 3ft of short-period swell, cross-shore winds, and no real quality. The energy is moderate at best (108 to 146 units). It’s a frustrating pattern.
Then we hit a real dry spell. From Sunday the 16th all the way through to Wednesday the 19th, it’s poor. Swell drops back down to 1ft to 5ft, winds are mostly cross-onshore, and the combined energy is weak. You’re better off doing something else.
Now, here’s the one tiny highlight: Thursday morning, August 20th. The swell picks up to a clean 5ft from the WNW with a period of 8 seconds. The wind goes glassy—absolutely dead calm. The combined energy hits 275, which is moderate. The conditions are described as glassy, so it’ll be smooth as a lake. This is the only time in the whole period where the waves are actually surfable, but even then, it’s only a score of 1 out of 10, so don’t expect perfection. The swell is small enough for beginners, but the glassy wind will make it the best it’s going to get. This is the standout, but it’s a modest one.
After that, it’s back to poor conditions right through to Monday the 24th. Winds turn onshore again, the swell drops, and the energy fades. The last day, Monday morning the 24th, shows a little 5ft swell with clean cross-off winds, but the energy is only 215 and the overall quality is still described as very ordinary.
So, to sum it up: Trestraou is a sheltered spot, and it shows. The best on offer is that brief, glassy window on the morning of August 20th. The rest is a long, quiet stretch with small, choppy, and poorly organised surf. If you’re desperate, that Thursday morning is your only real shot. Otherwise, it’s a waiting game.
Stay tuned, things can change.
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 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.
