The Lowdown
Alright folks, Rusty here. Let’s be real, this is a tough one. The whole 16-day window for Trestraou is a flat spell. Forget about scoring anything decent for a while.
We’re looking at a run of weak, small, and mostly messy conditions. The water is running a touch warmer than normal for this time of year, coming in at 66°, but that’s the only nice thing I can say about the ocean.
The first recommendation doesn’t even pop up until Thursday the 30th of July, and it’s a total write-off. We’re talking a poor 2ft swell from the WNW, with a weak 8-second period and a combined energy of just 83. To make matters worse, it’s a cross-shore, choppy mess with a moderate breeze. That’s not surf, that’s a washing machine.
Friday the 31st and Saturday the 1st of August are no better. Tiny, onshore junk. The swell drops to 1ft on Saturday, with the wind straight onshore from the north. It’s a battle just to get out, and even if you do, there’s nothing to ride.
The whole first week, right through to Wednesday the 6th of August, is a grim parade of weak, short-period swells under 3ft, mostly from the west. The wind is all over the shop, but mostly onshore or cross-onshore, making for bumpy, choppy surfaces. The best you’ll see is a tiny 1.0ft, 11-second groundswell early on Thursday the 6th, but it’s so weak (combined energy of 26) that it’s barely a ripple. It’s clean, but that’s like saying the parking lot is clean – still no waves.
The second week is a dead zone. From the 7th of August onward, the combined swell energy drops into single digits. We’re talking swells under 1ft with periods of 4 to 10 seconds. The wind does go offshore for a few days, with clean conditions on the 7th, 8th, and 9th, but there’s no swell to work with. It’s a flat, glassy lake.
Monday the 10th of August brings a tiny 2ft pulse from the northeast, but it’s a 4-second period, which is basically just wind chop. It’s glassy in the morning, which is a tease, but there’s no power behind it at all.
The rest of the run is the same story. Tiny, weak, and poorly directed. The highest combined energy in the second week is a paltry 57. For a spot that’s sheltered from the main swell, this is a typical, blank summer run. Forecasts can change, but right now, don’t even bother waxing up. There’s nothing on offer.
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.
