The Lowdown
Alright, folks, Rusty here. Let’s break down the next couple of weeks. Honestly, it’s looking like a slow grind. The system’s a bit lazy, and we’re not catching any big, clean lines for a while.
The water’s sitting at about 65°F at Trestraou, which feels a touch warmer than we’re used to for this time of year, but that’s about the only gift the ocean is giving us right now.
We start on Wednesday the 2nd. The swell is tiny and weak, only about 3ft from the W with a short 8 second period. The combined energy is a low 80, so it’s very weak. There’s a moderate offshore breeze which sounds good, but the models are calling it poor surf conditions. Thursday the 3rd is more of the same, a bit more size at 4ft but the period is still short and the wind is messy.
Friday the 4th gets up to about 5ft from the W, but the period is still short and it’s cross-off or choppy. It’s just not coming together.
Then we hit Saturday the 5th. This is your one decent chance in the first week. We get a 5ft groundswell from the WNW with a long 11 second period. The combined energy jumps to a moderate 521. The wind goes light and onshore from the NE, but it’s clean with clear skies. The models only give it a "marginal" nod, but for this stretch, that’s as good as it gets. Be aware, this spot is sheltered, so the swell has to wrap in just right. With that longer period, it might be a bit straight for a beach break, but the energy is there.
By Sunday the 6th, we drop right back down to knee-high 3ft with weak energy (135). The entire second week looks pretty bleak. There’s a pulse of swell on Monday the 7th of September with a very long 14 second period from the W, hitting 5ft with strong energy (604), but the cross-shore wind will chop it up. Tuesday the 8th has some clean 6ft surf but the condition rating is still poor.
If you are a beginner, most of this is small or unruly. Anything over about 5ft like we see on Friday the 4th and Tuesday the 8th might be a bit much for the less experienced, and it’s certainly not quality surf. Honestly, if you’re desperate for the first week, Saturday the 5th morning is the only time I’d even bother paddling out.
After that, it’s a long dry spell. There’s another pulse on Sunday the 13th, 5ft from the W with an 8 second period, but it’s onshore and unknown quality. The real bright spot, and it’s a long way out, is on Monday the 14th of September morning. The wind goes completely glassy at Trestraou. It’s just 3ft of swell with a moderate energy of 231, but glassy conditions are rare and magic. That’s the standout for the whole 16-day run, but we’re talking two weeks away, so keep your fingers crossed and don’t plan your life around it.
The final few days of the forecast see some onshore wind and weak swell. It’s a flat spell, plain and simple. I’ve seen worse, but I’ve seen a lot better. The board stays in the bag for most of it.
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.
