The Lowdown
G’day, Rusty here. Let’s take a look at the next couple of weeks at Cox Bay.
The water’s running about 59°, which is pretty much normal for this time of year, so no wetsuit surprises.
The first week, from Friday the 11th through Thursday the 17th, is mostly small and clean, but nothing to get too excited about. Friday afternoon is the pick: a clean 3ft SW groundswell with a 16-second interval and a moderate energy reading of 502. It’ll be fun, but small.
Saturday the 12th is a bit of a dud. Sunday the 13th jumps to 5ft but the period drops to a short 7 seconds, so it’ll be weak and lumpy. Monday the 14th has a clean 2ft SSW swell in the morning and then goes dead glassy in the afternoon with a 3ft WNW swell—a fun longboard wave, but not a standout. The rest of the week is pretty ordinary.
The second week, starting Friday the 18th, brings more of the same small, clean conditions: glassy mornings, clean afternoons, with waves in the 2-3ft range. It’s surfable, but you’ll be working for it.
Now, the real standout is Wednesday the 23rd. The morning is clean with a 3ft SW swell and strong energy of 574. But the afternoon is where it turns serious—the swell jumps to 8ft from the WNW with a short 7-second period and energy of 907. That’s a powerful closeout, way too big for beginners. Even for experts, it’s a heavy, thumping mess.
Then Friday the 25th afternoon brings a 4ft W groundswell with a 14-second period and energy of 994—strong and well-lined-up. But the big one is Saturday the 26th. The morning shows 7ft from the W with a 15-second period and a massive energy reading of 2167. That’s a serious swell. The afternoon is the one to circle: the swell holds at 7ft, the period drops to 14 seconds, the energy is still huge at 1922, and the wind goes glassy. That’s an excellent, powerful, clean day for experienced surfers only. Everyone else should be on the beach.
So overall: the first week is small and clean. The real action starts Wednesday the 23rd, but the true standout is Saturday the 26th—a proper, powerful, glassy day. Keep that one in mind. Crowds are possible at Cox Bay, so get out early.
Rusty out.

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.
