The Lowdown
Alright folks, Rusty here, but I’ll keep it in feet and Fahrenheit for you. Straight up, the finder is showing a total dud of a 16-day window for Trestraou. Every single session is marked as poor surf conditions, with zero recommendations across the board. It’s a rough outlook.
You’re looking at a long, quiet stretch from Monday the 10th of August through to Saturday the 22nd of August. Wave heights are tiny, from around 1ft to 3ft, with periods mostly between 7 and 10 seconds. The combined energy is weak, often under 100, and even when it climbs a bit (like 116 or 167), the wind is almost always onshore or cross-onshore, messing up what little shape there is. Water temp is about 66°F, which is normal for the season.
There is one spike on Sunday the 23rd of August. Swell jumps to 8ft to 10ft from the WNW, with a 10-second period. That’s a massive energy jump (1525 in the morning, 1187 in the afternoon). But the wind is a moderate cross-onshore, making it choppy. For a sheltered spot like Trestraou, that’s a killer. Plus, at that size, it’s expert-only. The conditions are poor, so it’s not a day worth chasing unless you’re a pro and don’t mind the mess. The days after drop back to smaller, jumbled waves.
It’s a real blank run. The area can turn around, but right now there’s nothing to recommend. Keep an eye on that 23rd if you’re feeling brave, but don’t hold your breath.
Stay patient.

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.
