The Lowdown
Alright, Rusty here again, but this time in feet and knots for the old-school crew.
Water temp is sitting at 57°, which is about 2° cooler than normal for this time of year—a little nippy, but nothing a 4/3 can't handle.
The immediate outlook is flat. Saturday the 22nd has waves barely knee-high, with a combined energy of 238, so don't bother. Sunday the 23rd morning has a 2-3ft west swell, but with a period of only 8 seconds, it's weak and won't have any drive. The glassy conditions are pretty, but the energy is pathetic (combined energy of 147).
Monday the 24th and Tuesday the 25th are blown out and tiny. Wednesday the 26th offers some clean 2-2ft SSW swell, but it's still small and the energy is only moderate. The real action starts at the end of the month.
The standout window is Monday the 31st of August through Tuesday the 1st of September. Monday morning brings 2-3ft SSW swell with a 16-second period and a solid combined energy of 630. That's a proper groundswell, and with a cross-off SE wind, it'll be clean. Monday afternoon is even better: 3-4ft west swell at 12 seconds with an offshore ESE breeze at 9 knots. That’s the session to circle on the calendar—clean, punchy, and fun. Tuesday morning the 1st of September is glassy with 2-3ft SSW swell. That whole stretch is money.
In the second week, Wednesday the 2nd of September has clean 4ft SSW swell in the morning, but the period is short (8 seconds), so it'll be a bit soft. Thursday the 3rd is a washout with strong onshore wind. Friday the 4th of September morning is glassy with 2ft SSW swell and a very long 19-second period. The energy is moderate (combined energy of 410), but that long period might make it close out on the beach—better for a point or reef.
Finally, Saturday the 5th of September morning shows a 7-8ft WNW swell with a 13-second period and a massive combined energy of 2047. That's a lot of power. The wind is just light cross, but this is expert-only territory. It'll be big, powerful, and with a cross-onshore breeze in the afternoon, it'll get messy. Not for the faint of heart.
So, if you want the best, aim for Monday the 31st of August into Tuesday the 1st of September. That's your call.

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.
