The Lowdown
Alright folks, let's get into the outlook for Trevone Bay.
The first part of this stretch is a proper mess. From Wednesday the 26th of August, we’ve got a solid block of poor surf. The wind is mostly from the south and southwest, blowing cross or cross-on, and it’s got some pace to it. The swell is tiny and weak, with a combined energy of just (62) on Wednesday morning, and the conditions just get worse. By Saturday the 29th, the wind is a strong breeze then a near-gale, with a blown-out 6ft to 8ft swell. It’s a total write-off for surfing. That Saturday and Sunday might be more interesting for the kite crew, but for us, it’s a no-go.
This run of bad luck carries on deep into the first week of September. We’re looking at a good week of poor conditions, with the wind not letting up. The swell does kick up a bit, but it’s always with a rough sea. It’s a long, frustrating wait.
But, there is a light. The one true standout, the only window to really get excited about, is the morning of Monday the 7th of September. The charts are showing a big, long-period groundswell from the west, pushing 11ft with a 10-second period. The combined energy reading is a whopping (2310). The wind is a moderate offshore from the south-southwest, and it’s forecast to be clean.
Here’s the kicker though – and it’s a big one. At 11ft, this swell is way too big for Trevone Bay. The data itself says it’s predicted to be too big for this break. This is for experts only, and even then, it’s going to be a handful. The period is solid, so it’ll have plenty of push, but that size at this spot is going to be intense. It’s a long-range call, so keep an eye on it, but if it lines up, it’ll be a day for the brave.
The day before, on the morning of Friday the 4th of September, you might get a decent little session. The swell is a more manageable 5ft from the west, the wind is glassy, and the combined energy is (463). It’s rated as a good surf condition, but it’s not a standout next to that Monday. It’s a clean, fun option if you’re about.
So, the next two weeks are a long, dry spell, followed by one massive, expert-only day. The water temperature is about normal for this time of year.

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.
