The Lowdown
Alright, Rusty here again, giving it to you in feet, miles per hour, and Fahrenheit. Let’s break down Trevone Bay.
Straight up, it’s a rough looking 16 days. We’ve got a big gap of poor conditions until we see anything surfable around Wednesday the 12th of August. The whole pattern is dominated by onshore and cross-onshore wind from the north and northwest, which just kills the wave quality. The swell is mostly out of the west.
Right now, the water is much warmer than usual for the season, coming in at about 66°F, which is a few degrees above average.
Let’s walk through it. Monday the 10th is a no-go with 3 ft of choppy junk. Tuesday the 11th has clean offshore wind from the SE, but the swell is only 1 ft with no energy; you can’t surf that.
Wednesday the 12th is your one real chance. On Wednesday afternoon, the wind goes glassy – dead calm – and the swell bumps up to 3 ft from the west. The combined energy is moderate at 110. It’s “surfable but very ordinary.” You might get a knee-high wave or two on a log. That’s the standout, and it’s a low bar.
From Thursday the 13th all the way to Tuesday the 25th, it’s largely a waste. The swell height rarely gets above 3 ft (1.0m), and when it does on the 25th, hitting 5 ft (1.5m), it’s lumpy and cross-chopped. Most of the time the wave energy is weak, under 100, or just in the low hundreds.
There are a few clean moments when the wind is offshore or glassy, like Monday the 17th morning and Wednesday the 19th afternoon, but the swell is tiny (1 ft to 3 ft) and has no power. You’d be bobbing around.
This kind of flat, wind-affected run is pretty normal for Trevone Bay when the pattern locks in like this. The only real advice is to aim for the glassy window on the 12th afternoon if you’re desperate for a few small ones on a soft-top or longboard. Otherwise, save the wax.
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.
