The Lowdown
Alright folks, Rusty here. Let’s have a look at what Cox Bay has in store for us over the next couple of weeks.
The window kicks off on Monday the 17th, but honestly, the first week is a bit of a slow burner. We’ve got some small, long-period groundswell filtering in, but the conditions are holding it back. The first real glimmer of hope comes on Friday the 21st morning, with a clean, cross-off breeze making the most of that 2ft SSW swell. It’s not big, but it’ll be rideable for a beginner.
Saturday the 22nd morning might be the standout of the first week. The wind goes glassy, and we get a little bump in size to 4ft from the west. The period is short, only 7 seconds, so it'll be a bit crumbly and weak, but that glassy surface will make it super fun for a longboard or a foiler. The combined energy is moderate (270).
After that, things drop right off. Sunday the 23rd and Monday the 24th mornings have glassy conditions again, but the swell is tiny at 1ft. It’s surfable but ordinary. The week of the 25th is a write-off for paddle surfing; the wind picks up, and the swell stays small. The end of the week, Thursday the 27th afternoon, actually sees a pulse of 5ft, but it’s straight onshore and choppy – that’s more of a kite-surfing setup than a clean wave for us.
The second week finally brings the goods. Friday the 28th morning is a beauty – glassy conditions and a clean 4ft from the WNW. The period is short (7 seconds), so it’ll be a bit soft, but the lack of wind makes it the best bet for a proper session that day.
But the true standout, the one you’ve been waiting for, is Monday the 31st of August. The morning session looks magic. We’re looking at a glassy 3ft SSW groundswell with a very long 16-second period. The combined swell energy is strong (664), and the forecast is calling it “very good”. That long period will favour the point setup, keeping the lines clean and the sets well-spaced. This is the best wave of the whole outlook. Tuesday the 1st of September also looks promising, with a clean cross-off breeze and a 3ft SW groundswell, keeping that energy up (771).
So, the long and short of it: the first week is for the patient, with Saturday the 22nd being the only real highlight. The second week has a clear winner on Monday the 31st. Get on it if you can.
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.
