The Lowdown
Alright, grab a coffee and listen up. It’s Rusty here, and I’ve been staring at the charts for Trevone Bay for the next couple of weeks. Straight up, it’s a tough read. The entire 16-day window is a battle with onshore winds and messy conditions. We’ve got a solid run of poor surf starting this Saturday, the 15th of August, and it doesn’t really let up until we get deep into the last week. The only real glimmer of hope comes right at the tail end.
The water temp is sitting about average for this time of year, so no nasty surprises there. But that’s where the good news ends. For the first 10 days, from the 15th through to the 24th, it’s a grind. The wind is mostly cross-onshore or onshore, blowing from the north and northwest, and the swell energy is weak to moderate at best. The combined energy rarely gets above 200 (129-323 range), and the period is short, around 6-8 seconds, meaning weak, lumpy, and poorly shaped waves. A couple of afternoons, like the 22nd, see a clean cross-offshore breeze, but the swell is too small and weak to make it worthwhile. The 24th of August Monday morning shows a jump in energy to 326 with a 5 ft west swell, but the wind is light cross-onshore, making it marginal. By Monday afternoon, the swell hits 6 ft with 466 energy, but the onshore wind kills it.
Then, on the 25th of August, Tuesday morning, we finally get a window. The wind turns light cross-offshore from the SSW, and the swell is a solid 5 ft from the west with an 8-second period and 363 energy. This is the standout. It’s not perfect, but it’s the best we’ll see. The waves will be clean and have some push. After that, it drops off again. The 26th is blown out, and the 27th is flat. The 28th of August Friday morning offers another small chance with clean cross-offshore winds and a tiny 2 ft swell, but it’s very small with only 54 energy.
So, bottom line: if you’re a surfer, pencil in Tuesday the 25th of August morning. That’s your day. The rest of the forecast is a write-off. For the rest of the time, with the consistent onshore wind and short-period swell, Trevone Bay is honestly looking more interesting for kite surfing than paddle surfing. It’s a long wait for a short window.
Rusty.

Information about the Trevone Bay Surf forecast
The above surf forecast table for Trevone Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trevone Bay can be found by selecting the local surf guide option on the grey menu. Our Trevone Bay 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 (Trevone Bay) 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 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. 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.
