The Lowdown
Alright, Rusty here. Let's break down what's in the water for the next couple of weeks.
Right off the bat, I gotta be straight with you: Trestraou is in for a pretty grim run. There isn't a single day in the next 16 where this spot is firing. We're looking at a long stretch of poor conditions, so temper your expectations.
The first few days, starting with Wednesday afternoon the 2nd of September, the cross-off wind is there, but it's just messy. Swell is a weak 5 ft from the W with a short, weak period of 6 seconds, which is just not pushing any real energy through (166). It feels like a waste of a paddle.
Thursday the 3rd and Friday the 4th don't get much better. The swell stays around 5 ft to 6 ft, period slowly gets a bit better, and the energy in the water picks up a little (around 232 to 530), but it's still plagued by cross-off or cross winds. On Friday afternoon, the wind goes cross-shore, and the wave comment tells us the conditions are just poor. You'll be fighting chop all session.
We get a glimmer on Saturday the 5th. Light offshore wind in the morning from the NNE, clean face, and a 5 ft groundswell from the WNW with a decent 11 second period and strong energy (524). It’s flagged as marginal, which is the best we’re going to get. The water temp is 65°, which is about normal for this time of year, so at least it’s not freezing. Still, I wouldn't be rushing down.
After that, it’s a dead zone. There’s a 7-day gap of truly poor and marginal conditions. The swell sizes drop right off to under 3 ft, the wind is often up, and the combined wave energy is barely registering. Monday the 7th sees a bump in size to 7 ft with a killer 12-second period and a huge 1098 reading on combined energy, but the wind is a fresh 22 mph cross-off, creating a nasty, bumpy surface. Tuesday the 8th is similar – big swell but rough.
The only other whisper of something is on Monday the 14th of September. That morning sees a 5 ft groundswell from the WNW with a solid 12-second period, and clean cross-off winds (625 energy). It's another "marginal" call. The water will be holding steady. Honestly, for a point break like Trestraou, that long period groundswell might actually line up nicely, so it's your best shot if you're desperate to get wet.
But for the most part, the scores for these days are all zeros or ones. This is a lean period. The wind is just never in the right place. With that much wind and the swell setup, you'd honestly get a better buzz from kite surfing than paddle surfing through this whole 16-day window. There are no standouts here.
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.
