The Lowdown
Alright, Rusty here. Let’s not sugarcoat it: Trestraou is looking bleak for the next two weeks. The entire 16-day forecast is a flat, poor-quality stretch. There’s no good surf to recommend. The first sign of any real energy doesn’t show until Wednesday, August 5th, and even then, the conditions are only barely passable.
Monday the 3rd and Tuesday the 4th are a complete loss – tiny waves from 2ft to 3ft, with cross-shore and cross-onshore winds ruining any chance of a clean wave. The water is 65°, right around normal for this time of year.
Wednesday the 5th of August is the only window worth mentioning. The morning swell comes in at 6ft from the west, with a moderate cross-offshore breeze keeping the surface clean. The combined wave energy hits 534 (moderate) – a big jump from the days before. The period is short at 8 seconds, so the waves will be a bit fat, but it’s the best we get. That afternoon, the swell holds at 6ft from the WNW, but the wind goes cross-shore and chops it up. Your best bet is Wednesday morning: a clean 6ft west swell, with a light offshore feel. It’s not great, but it’s the only standout.
After that, it’s a slow decline. Thursday the 6th drops to 4ft, and the rest of the first week is small, onshore junk. The second week (from Monday the 10th onward) is even worse – mostly knee-high slop and cross-onshore winds, with energy readings mostly under 100. There’s a big spike on Sunday, August 16th, with a 10ft WNW swell in the afternoon and a massive 1152 combined energy, but it’s blown out by a moderate cross-onshore wind. That’s expert-only, heavy, and dangerous.
Trestraou is a sheltered spot, and this run shows it. With no real quality on offer, all you can do is wait for a better forecast. The blank run is long – nearly the whole 16 days – but it won’t stay this way 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. 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.
