The Lowdown
Alright, Rusty here. Let's break down what's in store for the next couple of weeks.
It's gonna be a slow start, no way around it. Don't even bother waxing the board until later on. The first real shot of surf doesn't show up until Saturday, August 22nd, so you've got a long dry spell of over a week with nothing worth paddling for.
Alright, Saturday the 22nd of August is when it starts to wake up. Trestraou gets a proper groundswell from the West, pushing 6ft with a 9-second period and energy reading 455 – that's a solid, moderate pulse. The wind is cross-offshore from the West, so those faces are gonna be clean. This is a good size for the average surfer, fun but with some power.
Then hold onto your board for Sunday the 23rd of August. The swell from the WNW jumps up to 8ft with a 10-second period, and the energy rockets to 1440, which is serious power. That is strong, heavy water. The wind turns cross-onshore from the NNW, making it a bit lumpy and choppy. At this size, Trestraou is strictly for experts only – beginners need to sit this one out.
Earlier in the week, on Thursday the 13th of August morning, you get a clean session with a cross-offshore breeze and 3ft of swell, but the energy is lower at 237. It’s a sneaky option if you're desperate, but the main events are on the weekend. The water temp is 66°, which is normal for this time of year.
Honestly, the pick of the whole forecast is Saturday the 22nd, for that combination of clean, cross-offshore wind and a decent sized, well-ordered swell. Sunday is bigger and more powerful, but the chop makes it a rougher ride.
That's all I've got for you. Keep patient, that weekend is looking promising.
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.
