Right, mate, Rusty here. Let’s have a look at what’s on offer for Trestraou over the next couple of weeks.
Straight up, it’s a grim start. We’re looking at a long, dry spell with nothing worth paddling out for. The first proper week is basically a write-off. From Sunday the 12th right through to Sunday the 19th, it’s all tiny, weak slop with poor surf conditions. The swell is mostly under 2 feet, the wind is cross-onshore, and the water is just messy. There’s a bit of a reprieve on Wednesday the 15th and Friday the 17th with clean conditions and a light offshore, but the swell is still pitiful – 1 feet at best, with combined energy barely cracking 30 (32). That’s not surf, that’s a lake.
Then, on Sunday the 19th afternoon, the energy finally starts to show. We get a jump to 5 feet from the WNW, but the period is a short 6 seconds and the wind is cross-onshore. The combined energy hits 158 (moderate), but the quality is still poor. It’s going to be lumpy and weak.
The real shift happens from Monday the 20th. The swell builds, and by Tuesday the 21st we’ve got 6 feet from the WNW, with a period of 8-9 seconds. The combined energy is strong, hitting 552 in the morning and 561 in the afternoon. That’s proper power. But here’s the catch – the wind is onshore or cross-onshore, with a moderate breeze, making it choppy and difficult. That’s expert territory. For a beginner, that’s too big and messy.
The standout window, if you can call it that, is the last few days. Wednesday the 22nd still has 4 feet of WNW swell, but it’s a little smaller and cleaner. Then Thursday the 23rd morning is the real gem. You’ve got a clean 4 feet from the NW with a cross-offshore wind from the west at just 3 mph. Combined energy is 163 (moderate). The water is about average for the time of year. That’s the best on offer. It’s still not perfect, but it’s the only period where the wind is light and the surf is rideable. Expect crowds here, as Trestraou can get busy.
Saturday the 25th fades back to tiny, weak slop. Then Sunday the 26th and Monday the 27th bring a fresh 6 feet WNW swell, and this time the wind is offshore or cross-offshore, making for clean conditions. The combined energy is strong again (334 and 294). That’s a promising end to the outlook, but it’s over a week away, so don’t bank on it just yet.
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.

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.
