The Lowdown
Alright folks, Rusty here. Let’s talk about Trestraou.
Honestly, the next week and a bit is looking pretty grim. We’ve got a long dry spell of poor surf conditions with small, short-period wind swell and onshore winds messing things up. The water’s a touch warmer than normal for this time of year at 67°, which is nice for a dip but not much else.
From Thursday the 13th right through to Monday the 17th, there’s barely a wave worth paddling for. Swell heights are under 3ft, periods are short (5 to 11 seconds), and the wind is mostly cross or onshore. The combined energy is weak, often below 150. It’s flat, choppy, and frustrating.
Tuesday the 18th morning gives a little glimmer – a 4ft WNW swell, period 7 seconds, with clean conditions thanks to a light cross-offshore breeze. But the energy is still only moderate (132), and the wave comment says poor surf conditions. Not a standout.
Wednesday the 19th sees a bump in size – 5ft in the morning, building to 7ft by afternoon (WNW, 9 seconds). The combined energy jumps to 595, but it’s cross-on and choppy. Still, not good enough to recommend.
Now, Thursday the 20th – that’s the one that catches the eye. A solid 8ft groundswell from the WNW with a 11-second period, and the combined energy hits 1311 – strong to very strong. But here’s the catch: the wind is onshore from the NNE at 12 mph, and conditions are unknown. That’s a lot of raw power, but blown out. It’s big enough that only experts should even think about it, and with those winds, it’s more likely to be a washing machine.
The rest of the month stays small and messy, with a few clean moments on the 22nd and 23rd mornings (2ft, WNW, 9 seconds, light offshore winds) but no real energy behind them.
The best on offer? Honestly, nothing screams “go.” If I had to pick one, it’s the morning of Thursday the 27th – a 7ft WNW swell with an 8-second period, combined energy of 632, and a clean cross-offshore wind from the WSW at 19 mph. That’s a strong, clean swell, but it’s short period and big, so only for experienced surfers who know the bank. Even then, it’s a week away (August 27th) and conditions could change.
For the rest of us, it’s a waiting game.
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.
