The Lowdown
Alright, this is Rusty, and I’m looking at the surf forecast for Trevone Bay. Frankly, it’s a tough stretch ahead. The next week and a half is pretty much a write-off, with messy winds and junky conditions blocking any real quality. The water is sitting at 66° here, which is a touch warmer than normal for this time of year, so at least you won’t be freezing while you stare at the closeouts.
The first real glimmer shows up on the 6th of September. Early that Sunday morning, we’ve got a light offshore breeze from the southeast, and the swell is a tiny 2ft from the west at 9 seconds. The combined energy is a weak 85, so it’s small and gutless, but it’s clean. The afternoon improves a little with a 2ft west swell and a gentle offshore from the SSE, energy dropping to 58. These are rideable but very ordinary – a log or a SUP might get a few soft little lines.
After that, it’s back to poor conditions through the middle of the week, with strong onshore winds and messy, lumpy surf. We get a bit of hope on the 12th of September. Saturday morning shows a 4ft west swell, period of 8 seconds, with a light cross-off breeze from the SSE and a combined energy of 230. The afternoon gets even better: glassy conditions, a 4ft west swell at 9 seconds, and energy at 184. It’s still not big or powerful, but it’s the cleanest window in the whole stretch. The morning of the 13th also has a glassy start with a 2ft west swell, but it’s tiny.
Honestly, if you’re desperate for a session, the 12th of September afternoon is the standout. The glassy wind and small, clean waves make it the best bet, even if it’s not a classic. Everything else is a pass.

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.
