The Lowdown
G’day, Rusty here. Let’s be straight with you: the next couple of weeks at Trestraou are looking pretty grim for a proper surf. The models are showing a whole lot of nothing for most of the run, and when there is swell, it’s mostly messy and onshore. We’ve got a long, flat spell ahead, so don’t get too excited about the early part of this outlook.
The first real pulse of anything worth paddling out for doesn’t show up until Friday the 28th. Before that, it’s a wasteland. From now until then, we’re looking at wave heights mostly under 3 ft, with a lot of cross-onshore junk. The water temp is a touch warmer than normal for this time of year, coming in at 66°, which is a bit of a novelty, but it won’t save the surf.
The standout window is that Friday morning, the 28th. We’ve got a new WNW swell filling in at 5 ft with a 10-second period. The energy reading is strong, hitting 523, which is the real deal compared to the weak stuff we’ve seen all week. The wind is light and offshore from the WSW, so the surface is clean. This is your best bet by a mile. It’s still a week away, so treat it as promising but not locked in. The swell direction is solidly from the WNW, which lines up right with what this break wants.
Don’t bother with Friday afternoon though – the wind swings onshore and it gets questionable. And the swell is just over the 5 ft mark, so if you’re a beginner, it’s getting a bit too big for you. For the experienced crew, it’s game on.
After that, Saturday the 29th and Sunday the 30th have some rideable waves around 4 ft, but the winds are either cross or getting fresh, so it’s not going to be clean. The energy is moderate, but the quality just isn’t there.
The rest of the run, you’re looking at tiny waves or blown-out slop. There’s a big spike in energy on the 24th – we’re talking 13 ft from the NNE with a reading of 1924 – but it’s accompanied by a fresh cross-onshore mess and a thunderstorm risk. That’s not a surf day; that’s a stay-off-the-water day, unless you’re into kite surfing. That setup looks way more interesting for kites than paddle boards.
So, bottom line: mark your calendar for the morning of Friday the 28th. It’s the only true standout in the whole window. The rest is a lot of waiting. Forecasts can change, but right now, that’s the one to chase.
Rusty, signing off.

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.
