The Lowdown

Alright, let’s get down to it. It’s Rusty here, and I’ve been staring at the charts for our stretch of coast for the next couple of weeks. The short version is, if you’re looking for a classic, you’re going to have to be patient. We’ve got a lot of lumpy, wind-blown stuff on the menu before we finally see a couple of clean windows.

For the first week, honestly, it’s a write-off. The combination of onshore winds and junky, short-period swell is just going to make a mess of things at Trevone Bay. We’re talking poor surf conditions on a pretty consistent basis. The energy is there at times, like Wednesday afternoon with a 677 reading for combined energy, but that 7ft of W-NW swell is being hammered by a 22 mph NW wind. It might look big, but it’s going to be a close-out, bumpy mess. The water is 65°, which is a touch warmer than usual for the time of year, but you won’t be feeling it while you’re getting blown off your board.

Thursday brings a bit of a switch, with some cross-offshore wind and 6ft, but the period is only 7 seconds. That’s just short-period windslop, not proper surf. It’ll be peaky and frustrating. The start of the following week doesn't offer much either. There’s a brief window on Tuesday afternoon, the 15th, where we finally see some offshore wind with a 4ft W swell. The energy is moderate (286) and the period is a bit better at 10 seconds. That gives us our first “expect good surf conditions” call, but it’s a small window. This is our first real standout, but it’s not going to be huge.

The rest of that week follows a similar pattern. We see some clean conditions on the morning of the 19th, with glassy conditions and a 3ft WNW swell. It’s surfable and clean, but pretty average. It’s the kind of day where you can get a few fun ones if you’re in the right place, but nothing to get overly excited about.

Now, for the keen ones, you need to be looking at the very end of the run. By the 23rd, we start to see a pulse of long-period energy. The tail end of the forecast shows a W-NW swell picking up to 3ft, but the period is pushing 14 seconds. That’s proper groundswell. The combined energy is also climbing into the 440s, which is a solid sign. The wind is still a bit cross-on, which is a shame, but the sheer quality of that long-period energy should make it interesting. It’s far out, so treat it as promising but not certain. That Wednesday looks like the pick of the fortnight for anyone who wants a real wave, but it’s a long way off.

Between those brief clean moments, we’ve got long stretches of onshores, lumpy chop, and short-period junk. This isn’t a patch for beginners. When those swells push past 5ft, like that 7ft on Wednesday, the bay is going to be a handful. And if we ever get something over 8ft, that’s strictly expert territory. Given how much wind and onshore slop we’re dealing with, there might be a couple of days where the bay looks more interesting for a kite than a board.

So hang tight. Get a few small ones on the 15th if you’re desperate, and keep an eye on the end of the month. It’s a waiting game.

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.
