The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this 16-day window for Trestraou is a tough one. The forecast is just one long stretch of poor surf conditions, with no proper swell to get excited about and the wind playing havoc most of the time. There’s not a single standout session in the whole run, so we’re looking at a real dry spell.
The first few days are a write-off. Thursday the 6th of August, we’ve got a weak 1.0m swell from the WNW, but it’s a short-period 6 seconds and cross-on winds have it choppy and messy. Combined energy is only 98 (weak), and the water temp is 19°, which is 1.0° warmer than usual for this time of year – nothing too wild, just a touch above average. That’s about as good as it gets for a stat, because the surf is rubbish.
Friday the 7th and Saturday the 8th drop to tiny 0.3m to 0.4m swells, still poor quality. Sunday the 9th and Monday the 10th are no better, with onshore or cross-shore winds keeping the waves weak and uninviting. The whole first week is a gap of nothing – no recommendations, no hope.
Come Tuesday the 11th, we get a brief clean spell with cross-offshore winds in the morning, but the swell is only 0.4m, so it’s barely breaking. Wednesday the 12th morning has a light cross-offshore breeze and a 0.7m, 10-second swell, but it’s still labelled poor. By Thursday the 13th, the swell nudges up to 1.0m with a 10-second period, but it’s onshore again – combined energy hits 197 (moderate), but it’s junk.
The second week is more of the same. Saturday the 15th has 1.0m waves with cross-shore chop, Sunday the 16th morning sees a 1.3m swell from the west with clean cross-offshore winds, but the period is a short 8 seconds and the quality is still poor. Even the best-looking window – Thursday the 20th and Friday the 21st of August – shows 1.2m swells from the WNW with 9-second periods and combined energy hitting 232 and 239 (moderate), but the wind is either cross-offshore or cross-shore, and the surf remains poor. There’s nothing here worth paddling out for.
Honestly, this is a blank run. For a spot like Trestraou, it’s not unheard of to have these quiet stretches, but it’s a tough pill to swallow. Keep an eye on the forecasts – they can change, but right now, I’d leave the board at home.
Rusty.

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.

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.
