The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Cox Bay.
We’ve got a bit of a slow start, but once we get into the second week, there’s a couple of windows that’ll get the heart rate up. The first few days are pretty marginal. Tuesday the 4th through to the weekend are mostly small, with onshore winds messing things up. The water temp is sitting at 59°, which is about normal for this time of year, nothing wild there.
The first real glimmer of hope comes on Thursday the 6th in the morning. The wind is light cross-off, and the swell is 4ft from the WNW with a period of 7 seconds. The combined energy is moderate at 224. It’s clean, but it’s not going to be massive. It’s a nice little window for a beginner-friendly cruise.
Now, the standout period kicks off on Sunday the 16th. Sunday morning, the 16th of August, is looking like the pick of the entire forecast. The wind is glassy, and the swell is 3ft from the SSW, but with a very long period of 16 seconds. The combined energy is strong at 718. That’s a proper groundswell. It’s going to be clean as a whistle. Because it’s a long period swell, it’ll be better shaped, but at a beach and point setup like Cox Bay, it might break a little straight. Still, for a morning surf, it’s about as good as it gets on this run.
Monday the 17th also has some potential. The morning brings moderate offshore winds from the ESE at 16 mph, with a 5ft WNW swell and 8-second period. The combined energy is moderate at 481. It’s a bit of a punchier swell, and with the offshore wind, it’ll be clean. The afternoon has similar conditions with lighter offshore winds. This one is more for the intermediate to expert crew, as 5ft can be a bit much for beginners.
The other little highlight is Tuesday the 18th. The morning has a 2ft SSW swell with a 14-second period, clean cross-off winds. The combined energy is 242. It’s small, but it’s clean. Perfect for a longboard or a funboard.
Overall, the best on offer is clearly Sunday the 16th morning for the glassy, long-period groundswell. Monday the 17th is a close second for the punchier, offshore conditions. The rest of the week is a mix of onshore and small stuff, with a few clean windows in between.
Stay safe out there. 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.
