The Lowdown
Alright, this is Rusty. Let’s be straight with you – the outlook for the next sixteen days at Trestraou is a tough one. I’ve combed through the data, and honestly, there’s not a single session that’s worth paddling out for. The surf is just flat, weak, and the wind is all over the place. We’re looking at a long, quiet run with no real recommendations.
The whole 16-day window is a blank. From Friday the 31st of July all the way through to Saturday the 15th of August, the scores are all zero. It’s a grim stretch. The combined swell energy is tiny, mostly sitting between 9 and 88 (weak energy), with just one morning on the 9th of August hitting 102 (moderate energy), but even then the surf quality is poor, so it doesn’t matter.
The water temperature at Trestraou is 66°, which is a touch warmer than normal for this time of year, but you won’t be feeling it from the beach.
Let’s run through the misery. Friday the 31st has a 2ft swell from the WNW with a short 5-second period, but it’s cross-on at 20 km/h, so it’s choppy and messy. Saturday the 1st of August drops to 1ft with onshore wind, just terrible. Sunday the 2nd is 2ft with cross-on wind. It’s just a parade of small, weak, wind-affected slop all the way through. The swell height never gets above 3ft, and the periods are mostly short, between 6 and 10 seconds, so there’s no real push.
Even the “clean” days – like Tuesday the 4th of August morning with cross-offshore wind, or the 11th of August Tuesday morning with glassy conditions – the swell is only 1ft to 2ft. That’s ankle-to-knee high with no energy. You’d be floating around waiting for nothing.
The 14th of August has a little more size at 3ft from the W, with clean cross-offshore wind, but the period is just 7-8 seconds and the energy is still low (70-81). It’s just not enough to make a wave. It’s a flat spell, plain and simple. For a spot that’s as sheltered as Trestraou, this kind of blank run is more normal when the swell doesn’t line up. It’s not going to stay poor forever, but right now, it’s a write-off. If the wind keeps up and the swell stays this small, the setup looks more interesting for kite surfing than paddle surfing.
Keep your board waxed and wait for the next system. This one’s a dud.

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.
