The Lowdown
Alright, let me have a look at the charts for the coming weeks.
Well, I won't sugarcoat it – we're staring down a pretty bleak stretch for Trestraou. The sea is in a grumpy mood for a long, long time. We're talking from right now, through the 6th of September, right up until nearly the middle of the month, there's nothing really worth paddling out for. It's a two-week gap of poor conditions and marginal forecasts that just makes you want to wax the longboard and leave it in the car.
The only glimmer of a chance appears on Monday morning, the 7th of September. The swell will be a chunky 5 ft with a solid 14-second interval out of the west, carrying a big push of energy (960). That's proper groundswell, and Trestraou, being a sheltered spot, might just wrap enough to hold it. But the wind is a problem – a stiff 12 mph cross-off from the west. It'll be bumpy, and "marginal surf forecast or questionable tide conditions" is the word. It's not a stand-out, just the only thing on the menu that's not total garbage.
Then, you want to keep your eye on Tuesday morning, the 8th. This is the one. The swell is still solid at 6 ft from the west, with a decent 10-second period, delivering a moderate-to-strong energy (663). And the wind? 9 mph straight offshore from the southwest. That's a clean, groomed face right there. The water temp is sitting around 64°F with an anomaly of just 0.7°F, so it's right about average for early September. For a spot that doesn't see much action, this Tuesday morning session is your best bet. It'll be clean, but with only a 2/5 guidance rating, keep expectations in check. It's a quiet, local-scale wave, not a charging day.
After that, it's back to slop. We see a couple of morning windows later on, like Sunday the 13th with 6 ft but bumpy cross-off wind, and Monday the 14th with offshore light wind but a weaker 4 ft swell. Nothing screams 'go-time' from the roof.
Honestly, the whole window for Trestraou is a mess of poor surf quality and dodgy wind. Tuesday the 8th morning is the only true standout – a clean, offshore window with some size. That's your call. Don't sleep on it.

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.
