The Lowdown
Alright folks, it's Rusty here. Let's have a look at what the next couple of weeks has in store for us at Cox Bay.
Right off the bat, the standout session is this Saturday morning, the 5th of September. The water temperature is sitting around average for this time of year, so nothing wild there. We’ve got a solid 3 ft SSW groundswell rolling in with a very long period of 18 seconds, packing a moderate wave energy (525). But the real story is the wind – a glassy 3 mph from the NNE. That’s the kind of morning you set the alarm for. Expect super clean, lined-up waves. The long period means longer waits between sets, but the paddle out will be a breeze, and the shape will be quality. The only bummer is that crowds are possible here, so you might have some company for those gems.
Saturday afternoon though, the wind swings onshore from the WNW at 9 mph, and it turns into a bit of a mess. The swell holds at 3 ft, but the quality drops off a cliff.
Sunday morning the 6th is a write-off for me, with onshore winds again. By Monday morning the 7th, we get a cross-off breeze from the SSE at 6 mph, and the swell is still a clean 3 ft from the SSW, though the period has dropped to 14 seconds. It’s clean and surfable, but not the magic of Saturday.
The week is a bit of a mixed bag after that. We get small, clean windows on the 12th of September (Saturday) with a cross-off breeze and 3 ft SSW swell, and again on the 13th (Sunday) morning with glassy conditions and a smaller 2 ft swell. Both are alright for a cruise, but nothing to write home about.
Now, let’s talk about the 18th of September – this is where it gets interesting. Friday afternoon we see a jump in size to 8 ft from the WNW with a short period of 8 seconds. The wind goes glassy, and the combined energy jumps to a strong 894. That’s a big, powerful, short-period swell. It’s going to be a heavy, dumpy beach break. Over 8 ft is expert territory, and this is right on the edge. For the experienced crew, it’ll be a proper session. For beginners, stay well away.
The following morning, the 19th of September, we get a fresh offshore breeze from the east at 22 mph, cleaning up a 5 ft WNW swell. It’s got a bit of energy (553), but the wind is howling, so it’ll be a battle to get out and hold your line. More of a kite-surfing setup, if you ask me.
After that, the swell fades out quickly into the 20th, with a small 2 ft SW groundswell and a cross-off breeze. It’s a quiet end to the outlook.
So, to sum it up: Saturday morning, the 5th of September is your best bet – glassy, clean, and a classic groundswell. Then keep an eye on the 18th of September for the big stuff if you’ve got the chops.
Rusty.

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.
