The Lowdown
Alright, let’s see what’s on offer for the next couple of weeks. Things are looking pretty quiet right now at Cox Bay.
The first real chance to get wet comes on Monday, the 7th of September. We’ve got some small but clean swell pushing in. The morning will see a light cross-offshore wind from the southeast, keeping the 3ft SSW swell fairly tidy. The afternoon cleans right up with a glassy 3 mph breeze from the WNW, and the swell, though small at 2ft from the SSW, has a nice 14-second period. The combined energy is moderate, so there’s enough to push a shortboard around. This is the best on offer for the early part of the outlook – small but clean, and a good option for a beginner-friendly session.
Then we hit a lull. Tuesday and Wednesday look marginal with light cross-onshore winds and tiny, weak swell. The best bet in the next week is hands down Friday, the 11th of September. The morning brings a clean 3ft SW swell with a long 17-second period and a light cross-offshore breeze from the SSE. The combined energy is strong, giving it some real punch despite the size. The glassy afternoon is even better, with 3ft SW swell and 16 seconds of period. This is the standout – a proper groundswell that will peel nicely at the point. Expect clean, lined-up waves. Crowds are possible here, so get there early.
The following week stays small but offers some clean windows. Saturday morning the 12th is glassy, but the swell is small and the period is dropping. Sunday the 13th, the morning is glassy again with a 3ft SW swell, but it’s a bit weaker. The water temperature is 58°F, which is pretty much average for this time of year, so no surprises there.
By the second week, from Monday the 14th onward, the swell stays small with occasional clean glassy mornings, but nothing special. The best of that late period is possibly Thursday the 17th morning, with a glassy 4ft WNW swell and a short 7-second period – it’s okay for the area but not a standout. The 19th of September brings a tiny, very long-period SW swell (19 seconds), but it’s tiny at 1ft, more of a whisper than a wave.
Overall, if you’ve got a window, make it Friday the 11th. That’s the day to be out at Cox Bay.

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.
