The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for Trestraou all morning. Gotta be straight with you – this outlook is a tough one. The whole 16-day window is a bit of a write-off for proper paddle surfing. The data shows a long, quiet stretch with no real quality on offer. The first record kicks off on Saturday morning, August 1st, and from there, it’s a grim run of small, weak, and messy conditions.
The first few days, from Saturday, August 1st, right through the start of the following week, are downright poor. We’re looking at tiny waves, mostly around 1 ft to 2 ft, coming from the west. The swell energy is really low, often sitting in the 40s to 80s (weak), and the winds are either onshore or cross-onshore, which just chops everything up. It’s essentially flat and blown out.
There’s a slight shift around Tuesday, August 4th, when the wind goes cross-offshore from the WSW and WNW, cleaning the surface up a bit. The swell bumps up to 3 ft on Tuesday afternoon, with combined energy hitting 133 (moderate). But it’s still a short-period, windswell-like 8 seconds, and the surf quality is still rated as poor. Wednesday, August 5th, sees a bit more size, with 4 ft on the cards in the afternoon, and the energy reaching 181 (moderate) – but again, that 7-second period means it’s weak and crumbly, not holding any real shape. The wind is howling from the west at 22 mph, making it a clean but mushy mess.
The rest of the first week and into the second week is a rinse and repeat of small, weak surf. The swell rarely gets above 3 ft, and when it does, like on Tuesday, August 11th, afternoon, we see a 4 ft swell from the west with a better 10-second period, and energy jumps to 240 (moderate). But the wind is cross-onshore from the NW, so it’s choppy and messy. The water temperature is sitting about 66°, which is a touch warmer than normal for this time of year.
The final few days, from August 13th to the 16th, the wind goes cross-offshore again, cleaning things up, but the swell is tiny – mostly 1.0 ft to 2 ft – with no energy to speak of. There’s a spike on Saturday, August 15th, afternoon with a 4 ft swell from the WNW and 143 energy (moderate), and again on Sunday, August 16th, with 4 ft and 178 energy (moderate). But it’s still short-period, wind-affected swell, and the wind is a strong 19-25 mph. For paddling, it’s just not worth it. If you’ve got a kite, this is when the setup looks more interesting than a paddle board.
Honestly, there’s no standout session here. The best you can hope for is a clean but tiny wave on a Tuesday or Thursday, but it’s not going to be memorable. The forecast is pretty reliable for the first week, and it’s not good. The second week is more of the same, just with more promise of wind but no quality swell. A blank run like this is unusual for Trestraou, but it happens. Forecasts can change, so keep an eye on it, but right now, I’d give it a miss.
Rusty.

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.
