The Lowdown
Righto, let’s have a look at what’s in store for us here at Cox Bay.
Honestly, the next couple of weeks are a bit of a mixed bag. We’ve got a long stretch of small, messy stuff before anything really gets going. The first real glimmer of hope doesn’t show up until Tuesday morning, the 11th of August, when the wind drops to glassy. That morning, we’re looking at a tiny 2 ft swell from the SW, but it’s a long-period groundswell at 15 seconds, and the water is a touch warmer than average for this time of year at 60°. The combined energy is weak (247), but with glassy conditions, it’s the cleanest it’ll be for a while. Still, it’s a fickle little wave, so don’t expect much.
The real standout, the one to circle on the calendar, is Saturday afternoon, the 15th of August. The wind goes glassy again, and we get a jump in swell to 6 ft from the WNW, with a short period of 7 seconds. The combined energy jumps to a solid 881 – that’s moderate-strong energy. It’s a beach and point setup, so with that short period, it’ll be a bit crumbly, but glassy wind on a 6 ft wave is a proper fun session. The water is still about average for the time of year, no big anomaly there.
Then, look out for Tuesday morning, the 18th of August. This one’s for the experienced crew only. We’ve got a 7 ft swell from the W, with a nice long period of 14 seconds. The combined energy is very strong at 1881. That’s a proper groundswell, and at this size, it’s going to be powerful and clean on the glassy morning. It’s a bit of a beast, so only for those who know what they’re doing. The wind is light onshore, but the size and period mean it’ll still be a heavy session.
After that, things settle back down. The 21st of August (Friday morning) gives us another glassy window with a 2 ft SSW groundswell (14 seconds), worth a look for a quiet paddle, but it’s small.
Overall, the best bet is that Saturday the 15th for a fun, clean, medium-sized wave, and the big one on the 18th for the experts. The first week is mostly a write-off, so save your energy for the second week.

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.
