The Lowdown

Alright folks, Rusty here with a look at the waves on offer over the next couple of weeks. It’s a bit of a mixed bag right now, so let’s get into it.

Right now we’re looking at some small but promising groundswell. We’ve got a solid 3ft of swell rolling in from the SSW with a very long period of 16 seconds at Cox Bay on Sunday morning, August 16th. The combined energy is moderate at 520, and the water temp is sitting at 59°, which is about average for this time of year. The wind is onshore and light from the WSW though, so it’s a bit bumpy, making it more of a session for working on your pop-up than hunting for a barrel. The afternoon turns poor, so get out early if you’re keen.

Monday the 17th is pretty much a washout with onshore and cross-shore winds messing with that small 3ft SSW swell. Not worth paddling out for.

Now, Tuesday the 18th is our first real standout. The morning looks clean with clear skies and a light cross-offshore breeze from the SSE. That 3ft SSW swell has a long 14-second period, and the combined energy is still moderate at 525. The conditions are described as “clean”, so expect some nice little runners for a longboard or a fish. It’s not going to be huge, but for a Tuesday morning session, you could do a lot worse.

The rest of that week and into the next is pretty lackluster with small swell and poor wind states. The swell does pick up a little on Saturday the 22nd and Sunday the 23rd, with 3ft to 4ft of short-period windswell. Sunday afternoon the 23rd is actually worth a mention because the wind goes glassy from the SW, so those small, crumbly waves will be dead smooth. A good one for the log.

We then hit a long gap from Monday the 24th through to the end of the month with really poor surf conditions as onshore winds pick up. The swell stays tiny or gets blown out. The one exception is Monday, August 31st, which is our standout for the long-range forecast. We’ve got size on the way with a 6ft to 7ft WNW swell, an 11-second period, and a massive combined energy of 974 on Monday morning, jumping to 1283 in the afternoon. The morning has a light cross-onshore breeze from the SSW, so it could be a bit textured, but with that much energy, Cox Bay will be firing. Keep in mind though, once it gets over 5ft, it’s too big for beginners, and over 8ft it’s expert territory. This is a promising prospect for the end of the month, but it’s a long way out, so don’t book the time off just yet.

Keep an eye on it. This is Rusty, signing off.

Information about the Cox Bay Surf forecast

The above surf forecast table for Cox Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cox Bay can be found by selecting the local surf guide option on the grey menu. Our Cox 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 (Cox 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 Cox 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.
