The Lowdown
Alright, Rusty here again. Let's bail on the metric and run this through in feet and miles per hour for the old-school crew.
The outlook is still bleak. Trestraou is looking at a long, rough stretch with hardly anything worth a paddle. For a full eight days, it's poor to marginal. Water temp is 66.1°, which is a touch above the seasonal average, but that’s the only warm note in this cold forecast.
The closest you get to a wave worth looking at is on Saturday, September 7th in the morning. You've got a 5.6ft swell out of the West, with a very long 13-second period. The combined energy is moderate at 794, but that much period means it'll be long lines that tend to close out on a beach break. It’s the best-looking pulse in the first week, but far from perfect.
Thursday morning, September 10th, brings a bigger 7.2ft swell from the West, but with a short 8-second period. The wind is cross-off from the WSW at 15.5 mph, keeping the faces clean. Combined energy is moderate at 595. That 7.2ft is big enough to be an expert-only session.
The rest of the first week is trashed by cross-shore winds. The second week, from the 12th onward, just fades into nothing. Swell drops below 3ft, combined energy falls into the weak range (80-99). There’s a glassy 3.3ft on Thursday the 17th, but it's a total dud.
No true standout here. The best it gets is a choice between a tricky long-period swell on the 7th or a bigger, expert-only window on the 10th. Neither is worth getting excited about. Save your energy.

A general guide to surfing at Trestraou can be found by selecting the local surf guide option on the grey menu.

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.
