The Lowdown
Alright, Rusty here. Let me give you the honest story on what’s cooking for this stretch. I’m looking at Trestraou.
Right off the bat, I’ve gotta be straight with you – it’s going to be a long wait. The next week is pretty much a write-off. We’ve got a run of days from Thursday, August 13th, all the way through to Saturday, August 22nd, where the surf is either tiny, blown out, or straight-up pitchy. There are mornings with some cleanish vibes, but the swell is barely registering. A few sessions mid-week have a bit of shape, but the onshore flow or cross-chop just kills it. You’d be fighting a losing battle. It’s one of those blank runs that can happen, but don’t worry – it tends not to stay poor forever.
Now, Sunday morning, August 23rd… that’s the one spark in this whole 16-day forecast. It’s looking like a genuine standout. We’re getting a solid pulse of groundswell from the WNW at 6 ft, and with that 8-second period, it’s got enough punch for some decent fun. The water is a touch warmer than normal at 67°, so that’s a bonus. But here’s the real kicker – the wind is showing as “glass” from the SE. That’s about as clean as it gets. It’ll be glassy perfection for the early session. The combined swell energy is strong at 448, so there’s a good amount of power in the water. This is the morning to paddle out. Keep in mind, crowds are possible here, so get in early.
Monday, August 24th, offers a follow-up with a decent 5 ft WNW swell from the morning, and clean conditions with a cross-offshore wind from the W. It’s not as strong as Sunday, but it’s still a very solid option.
The rest of that second week fades back into weak or wind-affected slop. Friday, August 28th, shows a bump in size to 6 ft from the WNW, but with a strong onshore breeze from the NE, that’s going to be messy. Better for the kite crew than a paddle surfer.
So, to sum it up: This location is quiet for a solid week, then you get that one must-do window on Sunday morning, August 23rd. Make the most of that glassy, 6 ft WNW swell. That’s your only real gem in here.
Rusty.

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

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.
