The Lowdown
Alright folks, Rusty here. Let’s have a look at what Trevone Bay has on offer over the next couple of weeks. Straight up, the first week is a near-total write-off thanks to a persistent run of onshore and cross-onshore winds, so don’t even bother waxing up until later.
The first real hope appears on Sunday the 20th, but it’s only marginal at best. By Monday morning the 21st, it’s tiny at 2.6 ft from the west, with a period of 10 seconds. The combined wave energy is weak (177), and while the wind goes glassy, the swell is just too small to get excited about. That’s the start of a few days of small, weak surf.
Tuesday the 22nd morning is when things perk up a bit. Trevone Bay sees a clean 3.6 ft west swell with a 12-second period, and glassy conditions. The combined energy is moderate (582). That’s a window for a longboard or a foiler if you’re keen, and the water temperature is sitting at 64.2°, which is a touch warmer than normal for this time of year.
The standout (and I mean the only true standout) of the whole outlook is Wednesday the 23rd. The morning shows 4.6 ft from the WNW with a solid 13-second period and light cross-offshore east winds. The combined energy is moderate (689) and the conditions are clean. That’s the pick of the fortnight – decent shape, clean face, and manageable size for a range of surfers. The afternoon holds similar quality but a little smaller.
After that, the end of September and into the 30th gets messy. Thursday the 24th and Friday the 25th are blown out by strong offshore winds that make it clean but tiny. Then Saturday the 26th morning serves up a bigger 5.2 ft WNW swell with a long 14-second period and moderate offshore winds. The combined energy is strong (1024), but that long period will make it a bit straight for a beach break like this. Still, it could offer some powerful lines for experienced surfers. The afternoon stays clean and fun.
We then hit a massive spike on Monday the 28th with a dangerous 14.8 ft west swell and cross-onshore winds. Combined energy is very strong (3865). That’s not for paddling – that’s a full-on washing machine. By Tuesday the 29th, it drops to a still-chunky 8.2 ft with onshore winds, only suitable for experts. Wednesday the 30th afternoon sees a big 9.8 ft WSW swell but with good offshore winds – the file says it might actually be too big for this spot, so keep that in mind.
Overall, look to Wednesday the 23rd for your best chance at clean, quality surf, and maybe Saturday the 26th morning if you’re after something bigger. The rest is mostly a battle with the wind.

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.
