The Lowdown
G’day, Rusty here. Lookin’ at the full 16-day stretch for Trestraou, I gotta be honest – it’s pretty flat and boring for most of it. There’s a big gap with nothin’ worth paddlin’ for until the second week, where a punch of bigger, cleaner swell pops up. Even then, conditions are shaky.
Alright, startin’ off Tuesday mornin’, 01 September. We got a 4ft swell from the west, period around 9 seconds, with light cross-offshore wind from the southwest at 6 mph. Water temp’s at 65°, which is about a degree warmer than usual for this time of year – nothin’ wild, just a little on the mild side. Combined energy is moderate (281). It’s clean, rideable, but real ordinary – nothin’ special.
The rest of the first week and into the second is a washout. From Tuesday afternoon through to the mornin’ of Tuesday, 08 September, the surf is consistently poor – small, choppy, onshore winds, and weak energy. There’s a gap of about six days where I wouldn’t even wet a line. The afternoon of the 8th shows a 5ft west swell with cross-shore wind, but it’s still poor.
Now, here’s the one blip worth gettin’ hyped for. Wednesday mornin’, 09 September – that’s just over a week away – we got a solid 7ft swell from the WNW, 10-second period, and clean offshore southwest wind at 16 mph. Combined energy is strong at 961. That’s a powerful, clean-lookin’ groundswell for the experienced crew. The 7ft puts it in the “experts only” zone. Period’s 10 seconds – decent groundswell, but not super long, so it should shape up okay at this sheltered spot. Crowds can show up here sometimes, so expect company if you’re game.
After that, it drops off quick. Thursday the 10th is messy again, and from Friday the 11th right through to Wednesday the 16th, it’s poor – mostly onshore or cross-onshore winds, small swell, and weak energy (values like 126 to 410). The 15th sees a 3ft west swell at 12 seconds, but it’s blown out by onshore winds from the northeast. Not worth it.
Honestly, if you’re chasin’ a wave, the 09 September mornin’ is your only real bet. It’s a standout for the whole period, but it’s a long way out, so keep an eye on the forecast.
Rusty.

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.
