The Lowdown
G’day, Rusty here. Let’s be real – for the next couple of weeks, Trestraou is a tough watch. The set-up’s pretty sheltered from the swell we’re getting, and the wind’s a mess. There’s a big run of poor conditions until the end of August, but things do start to look a touch better as we roll into the first week of September.
Right now, Friday the 28th through to Saturday the 29th, the wind is howling cross-off or cross, blowing 12 to 25 mph, and the swell’s a confused short-period bump. Not worth paddling out. Sunday morning the 30th is where we get our first real sniff of decent surf. We’ve got clean 6 ft swell from the west, with a period of 9 seconds, and the wind goes offshore from the southwest at 12 mph. The combined wave energy is moderate at 505, and the conditions are labelled as good surf. That’s the only standout in the near-term. The crowd factor is ‘sometimes’ so you might get a few out, but it’s your best shot until later.
After that, it goes messy again through Monday and Tuesday, with wind picking up and the swell getting a bit sloppy. The combined energy gets high on Monday morning at 1124, but with 8 ft from the west and cross-off winds, it’s a bit of a beast and not clean.
Now, for the more promising but less certain stuff: Saturday the 5th of September morning. We’ve got a 5 ft swell from the west-northwest, period stretching out to 12 seconds – that’s proper groundswell. The combined energy is moderate to strong at 660, and it’s clean with light offshore wind from the southwest at 9 mph. This one’s a true standout, and the longer period will give it shape, though at a beach break it might break a bit straight. Keep your eyes peeled. Also, Wednesday the 9th of September morning sees a clean 4 ft west swell, period 11 seconds, with a light offshore from the south-southwest at 12 mph – surfable but ordinary, with moderate combined energy at 338.
Water temperature is about average for the time of year, nothing unusual there. For the most part, the setups look more interesting for kite surfing than paddle surfing when the wind is strong and the quality poor. The best advice? Hit Sunday morning the 30th of August or Saturday morning the 5th of September, and don’t expect much else.
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.

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.
