The Lowdown
Alright folks, let’s get straight into it. Rusty here, and I’ve gotta be honest with you straight up – the next couple of weeks are looking pretty grim for any kind of decent surf around Trestraou. We’ve got a long stretch of small, weak, and messy conditions ahead, so don’t get your hopes up too early.
The first real chance of anything rideable doesn’t pop up until Sunday, August 23rd, but even then it’s a real dog’s breakfast. The swell is tiny at 3 feet out of the ENE, with a period of only 5 seconds – that’s pure wind chop, no power behind it. The wind is howling out of the east at 19 mph, cross-on, making it lumpy and all over the place. The combined energy is a weak 56, so you’re really just fighting the wind for nothing. Not worth paddling out.
The whole week following is flat or close to it. Monday and Tuesday of that week are tiny, with swell barely reaching 0.7 feet and 1 feet, and the wind is still ugly. Even though Tuesday morning, August 25th, goes glassy with a clean surface, the swell is from the NW at 1 feet with a period of 11 seconds, so there’s just not enough height to do anything with it. The energy is only 34.
We finally see a bit of hope on Wednesday morning, August 26th. The wind swings to the south at 9 mph, blowing offshore, and the swell picks up to 2 feet from the west with a 9-second period. That’s a clean, gentle offshore situation, but the swell is still miniature and the combined energy is only 58. It’s a glassy little wave, but you’ll be scratching for any sort of power.
The end of the week and into the weekend sees a jump in swell size, but the quality is still poor. Thursday, August 27th, has a fresh offshore wind, but the swell is only 1 feet in the morning, and then jumps to 4 feet in the afternoon with a short period of 8 seconds. The energy is up to 195, but it’s a short-period, wind-swell combo that’s going to be messy. Friday, August 28th, brings bigger swell – 5 feet from the west with a 9-second period, and the energy hits 383 – but the wind is cross-off from the WSW at 25 mph, meaning it’s clean but really strong. The swell is over 5 feet, so it’s getting a bit too much for beginners, and the wind will make it a battle.
Saturday, August 29th, is the biggest day of the whole period, with 8 feet of swell from the west and a 9-second period. The combined energy is a powerful 941. But here’s the thing: at 8 feet, this is expert-only territory, especially at a beach break. The wind is cross-off from the west at 19 mph, so it’s clean, but the size and power are going to be intimidating for most. The period is short, so it’s going to be a heavy, dumping shorebreak, more suited to a tow-in crew or honestly, it looks like a much better setup for kite surfing than paddle surfing.
After that stormy weekend, the swell drops off quickly. The first week of September is all small and weak again. We get a tiny window on Monday, September 7th, where the wind goes offshore from the south at 9 mph, the swell is 3 feet from the WNW with a long 11-second period, and the energy is 234. It’s the first time the guidance mentions anything other than “poor surf conditions,” calling it “surfable waves but very ordinary conditions.” The wind is gentle offshore, so it’ll be clean, but the swell is small and inconsistent. It’s not a standout, just the least bad option in a very long, bleak forecast.
So, to sum it up: the only real standout, if you can call it that, is the clean, offshore window on Wednesday, August 26th, for the smallest of waves. For the bigger, more powerful stuff on Saturday, August 29th, it’s expert-only and the wind is howling. The rest is a long stretch of flat, weak, or windy nonsense. Stay patient, lads. The ocean will turn around eventually.

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.
