The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Trestraou over the next couple of weeks. I gotta be straight with you – it's not looking like a classic run. We've got a long wait ahead before anything really clicks.
We are looking at a pretty bleak start. The first couple of days, Wednesday the 26th and Thursday the 27th, are a write-off. Tiny little knee-high 2ft waves from the west with a short, weak 8-second period and weak energy (32 to 54). The wind is messy, and the water is a touch warmer than usual for late August. It's not worth paddling out for. Friday the 28th shows a pulse of swell, but it's sloppy and the wind gets up, making for chunky, blown-out conditions. The water temp is a touch warmer than usual for this time of year.
There's a bit of hope on Sunday morning, the 30th of August. We've got a clean 7ft west swell rolling in with a moderate 10-second period, offering moderate wave energy (745). The wind is a moderate offshore from the southwest, so it should be clean. The water temp is a touch warmer than usual. This is probably the best window we've got in this whole outlook. Monday morning the 31st gets a bigger, more powerful 8ft swell (energy hitting 1111), but the wind gets messy, turning it into a bit of a washout. That size is getting into the experts-only territory, too.
After that first weekend, things just fade out. We've got a long, barren stretch from Tuesday the 1st of September all the way through to basically the end of the forecast. There's the odd morning with a clean, small wave, like Saturday the 5th of September, which has a nice glassy 5ft swell from the WNW with a decent 9-second period (energy 294). For a moment there, it looks surfable, but then the wind switches onshore in the afternoon. The rest of the week shows tiny, weak, and often onshore slop – not worth getting wet for.
So, to call it: The standout, and really your only genuine shot, is Sunday morning, the 30th of August at Trestraou. The 7ft west swell with offshore wind will be the cleanest and most fun it gets. It's not a classic, but it's what we've got. Later on, the glassy period on Saturday morning the 5th of September is also a window for a sneaky session, but it's small and inconsistent. The rest is a long, quiet gap.
That's how I see it. Stay patient.

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.
