The Lowdown
Alright folks, Rusty here. Let's have a look at what Trevone Bay has got cooking for us over the next couple of weeks.
Honestly, it’s a pretty bleak picture for the next week or so. The surf is just not cooperating. We’ve got a lot of days with tiny, weak waves—mostly around 0.7 ft to 1 ft—and the wind is all over the place. There are a few windows of clean offshore wind, especially on Saturday the 8th and Tuesday the 11th, but the swell is so small you’d be fighting for a dribble. The wave energy is pitiful, with readings like 19 (weak) on Saturday afternoon and 29 (weak) on Tuesday morning. It’s just not worth paddling out for.
We start to see a little more size around Wednesday the 12th, with a 3 ft to 3 ft swell from the west. The morning has a fresh offshore wind from the SE at 30 km/h, which would make it clean, and the energy bumps up to a moderate 125. Still, the quality is poor, so it’s a bit of a tease. By Thursday the 13th, the swell pushes up to 4 ft with a period of 11 seconds, giving us a moderate 317 energy, but the wind swings onshore from the NW, ruining it. That pattern holds through the weekend—more size, but the wind is onshore or cross-onshore, making it choppy and messy.
The real standout, and I mean the only one that’ll get your heart pumping, is Wednesday the 19th and Thursday the 20th. This is a long-range call, so don’t book your flights yet, but the models are showing a serious pulse. On Wednesday the 19th morning, we’re looking at a 7 ft swell from the WNW with a strong 454 energy. The wind is onshore from the NW at 25 km/h, which is a bummer, but the size is there. By Thursday the 20th morning, it gets even bigger—8 ft from the WNW with a whopping 942 energy. However, the wind is a fresh cross-onshore at 35 km/h, making it lumpy. This is strictly for experts only. That 8 ft is too big for beginners, and the period is a short 9 seconds, so it’ll be a bit walled-up and raw. The break is a fairly exposed beach, so with that much west swell and a short period, it’s going to be a washing machine. Honestly, for a setup like this, with that much wind and swell, it might be better suited for kite surfing than paddle surfing.
The water temperature is sitting at 66°F, which is a touch warmer than normal for this time of year, so at least you won’t be freezing your toes off while you’re watching the closeouts.
So, to wrap it up: the next week is a write-off. The only real action is the big swell on the 19th and 20th, but it’s for the brave and the experienced. For everyone else, keep your board in the car and wait for a better forecast.
Rusty.

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 Trevone Bay 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.
