The Lowdown
G’day, Rusty here. Lookin’ at the next 16 days for Trestraou, it’s a bit of a flat patch, honestly. The first week and a half is pretty much a write-off for any decent surf. There’s a gap from the start all the way through until the 10th of August where the conditions are just poor – tiny, weak, messy waves. The swell energy is well under 100 and the wind is mostly cross or onshore, so don’t bother paddling out until then.
The only real standout comes on Monday the 10th of August. It’s not perfect, but it’s the best we’ve got. The morning has a 8ft swell from the west, with a period of 8 seconds. That’s a solid, powerful wave, but it’s short-period, so it’ll be a bit of a dumpy closeout at the beach. The combined energy reading is 746, which is strong, but the wind is a gentle cross-shore breeze, making it a bit choppy. The afternoon is similar, with a 7ft west swell and 581 energy, still cross-shore. This is definitely expert territory – over 8ft in the morning, so it’s only for the experienced crew. Beginners, steer clear.
Earlier, on the 9th of August, there’s a 7ft swell with 876 energy, but the cross-onshore wind will ruin it. Then on the 11th, the morning sees a glassy 3ft west swell, but it’s too small and weak to get excited about. The rest of the week after the 10th fades away into tiny, messy leftovers.
So, if you’re keen, your best bet is the morning of the 10th. It’s the only window where the size and energy are up, even with the cross-shore chop. For the rest, it’s a waiting game. Keep an eye on the forecast, though – it tends not to stay this flat for long.
Rusty.

A general guide to surfing at Trestraou can be found by selecting the local surf guide option on the grey menu.

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.
