The Lowdown
Right, ol’ mate Rusty here, looking at the Trestraou forecast for the next couple of weeks. And I gotta be straight with you—it’s been a rough start. The opening days are a write-off. We’ve got a run of poor surf, choppy cross-on winds, and nothing worth paddling out for. The good news is things do eventually turn, but you’ll be waiting a while.
The first sniff of anything decent doesn’t show up until Tuesday the 25th of August. Even then, the swell is tiny—only 1.0ft to 1ft with a glassy window on Tuesday afternoon. The water’s sitting at 66°, which is a touch warmer than normal for this time of year. It’s a novelty session, not a proper surf.
The pattern really starts to shift on Monday the 31st of August. That’s the standout. The swell picks up to a solid 6ft from the west, with a period of 9 seconds, and we’ve got light offshore winds from the SSW. The combined energy is strong at 487 (moderate wave energy). The surf break is Trestraou, and the swell direction is matching the optimum WNW swell direction. The wind is clean, and the waves will have some punch. The morning of the 31st looks the pick of the whole period. The afternoon is also good with 6ft, but a touch of cross-off wind.
After that, it’s a bit of a mixed bag. The first week of September sees a drop in quality and size, with Tuesday the 1st and Wednesday the 2nd being ordinary. Thursday the 3rd shows a pulse of 8ft, but it’s cross-onshore and choppy—that’s expert-only territory, and not great shape. Friday the 4th has a clean 5ft in the morning, but it’s only surfable, nothing special.
So, if you’re keen, hold out for Monday the 31st of August. That’s the day the stars align, even if the rest of the window is a grind. It’s been a long flat spell, but it won’t stay poor forever.
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.

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.
