The Lowdown
Alright, let's get into it. It's been a tough go at Trevone Bay lately. The swell's been around, but the wind has been rubbish. We're looking at a long stretch of poor conditions from now through the next week or so. The water's a touch warmer than usual for this time of year at 65°, but that's the only good thing.
There's a real gap here—over a week of nothing much worth surfing. The wind is mostly cross or onshore, and the wave energy is just moderate, mostly in that 200 to 500 range. You'll see some northwest swell on Friday the 11th and Saturday the 12th, but the wind is all wrong, and the period is short, so it's just a mess.
The light finally turns on around the 23rd of September. That Wednesday morning, we get a nice 8ft swell from the west, but the big story is the wind swinging offshore from the southeast. It's light, the surface will be clean, and the combined energy is a solid 689 – that's a real push of power.
But the real standout is the afternoon of the 23rd. Swell jumps to 10ft from the west with a 10-second period, and the energy is massive at 1462. The wind is a light cross-onshore. Now, 10ft is serious size for Trevone, so this one is strictly for the experts. It's going to be big and powerful.
Then on the 24th of September, the morning is a beauty with a 7ft west-northwest groundswell, a long 12-second period, and clean offshore winds from the east-southeast. That’s proper quality stuff, with energy at 1221. The afternoon stays clean but drops off a bit. There’s a real good run of waves here, but it's a long way off, and with that size, it's for the experienced crew only.
So, keep the board in the car for the first week, but that last week of the forecast is looking like it could have some absolute crackers if you can be patient.

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.
