The Lowdown
Alright, let’s talk Trestraou. It’s a rough outlook for the next couple of weeks, to be honest. The water is about 65°F, which is pretty average for the season, nothin’ special.
The first real chance you’ve got doesn’t come until Friday, August 21st. From now until then, through Thursday, August 20th, it’s mostly flat to tiny, with bumpy onshore winds and no real energy. You’ll get a few days where the swell picks up a bit, like Wednesday, August 12th, with a combined energy of 106, but the wind’s all wrong, and the waves are just poor. Not worth wettin’ a suit.
Then, Friday, August 21st morning is the only real standout in the whole 16-day window. The swell jumps to about 7ft from the WNW with a period of 9 seconds, and the energy hits 697—solid, moderate energy. The wind turns offshore from the SSW at 9 mph, so it’ll be clean and glassy. This is a proper groundswell, and with that offshore wind, Trestraou could have some fun, well-shaped waves. It’s a bit of a beast at 7ft, so I’d say it’s for the experienced crew only. The swell direction lines up perfectly with what works best here. Just remember, it’s a long-range forecast, so it’s lookin’ good but not guaranteed.
After that, it drops off fast into smaller, choppier stuff. So, bottom line: you’ve got a long wait, but Friday, August 21st morning is your best shot. The rest of the time, it’s a skip unless you just wanna float around.

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.
