The Lowdown
Alright folks, Rusty here with the long-range look for Trestraou. Gotta be straight with you, it's a pretty grim outlook overall. We've got a solid 16-day window, but the first week is a write-off for any decent surf. We're looking at some small windows of clean but weak surf, and only a couple of sessions that even get close to being worthwhile.
We're kicking off on Thursday, the 20th of August. The water is sitting at 66°, which is a touch warmer than normal for this time of year. But don't get excited, because the surf is a mess. We've got a 7ft swell from the WNW, packing a moderate 662 combined energy, but it's getting torn apart by a 16 mph cross-offshore wind. It’s just poor conditions.
That theme continues right through the weekend and into the start of the next week. The swell drops right off, and the wind stays onshore or messy. There's a notable gap in quality surf from Thursday the 20th right through to Wednesday the 26th of August. A lot of small, weak, or wind-affected bumps, nothing you'd want to paddle out for.
Now, the first real glimmer of hope comes on Thursday the 27th of August. The morning session has a 5ft WNW swell, period of 10 seconds, with 443 combined energy, and the wind goes offshore from the SSW at 16 mph. That's a solid moderate offshore breeze, keeping things clean. This is the standout of the entire forecast. It’s not huge, but it’s the only window where everything comes together for clean, surfable waves.
Friday the 28th of August starts with a similar 5ft swell at 9 seconds from the W and 328 combined energy. It’s clean, but the wind is a fresher 19 mph cross-offshore. It’ll be choppy and a battle.
Then we get another big gap. Saturday the 29th has a bigger 7ft swell from the WNW, but it’s getting hammered by a strong cross-shore wind. Not good. Sunday and Monday see the swell hanging in there, but the quality is marginal at best. Things get big again on Monday the 31st of August with a 10ft WNW swell packing a massive 2306 combined energy, period of 11 seconds. That is serious power. But it’s cross-offshore with a fresh breeze. At over 8ft, this is expert territory only, and the wind will make it a lumpy, challenging beast. Not exactly a friendly day at the office.
After that, we’re back into small, weak, and often onshore slop for the first week of September. The energy drops right off. A few morning sessions on the 3rd of September have offshore wind, but only 3ft of swell, nothing to get excited about.
So, to sum it up for Trestraou: we have one true standout, and that’s Thursday morning the 27th of August. The rest of this 16-day run is a lot of waiting and watching. If you’re an expert looking for a real challenge, maybe look at that big Monday the 31st of August, but it’s not going to be pretty.
Stay patient, crew. Rusty out.

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.

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.
