The Lowdown

Alright folks, Rusty here. Let’s get into it for Cox Bay.

We’ve got a bit of a slow start with some small, weak swell rolling in. The waves are just not doing much through the first few days, with tiny 2ft to 2ft swells and a long period, but not enough height to get excited about. The energy is moderate to weak, hovering between 219 and 298. Tuesday the 25th through Thursday the 27th sees mostly cross-off or light offshore winds, which is clean, but the surf is just marginal. Friday the 28th morning is looking glassy with a tiny 1ft swell from the SSW—perfect for a beginner to get out. But the real standout early on is Sunday, August 30th, early morning. We’ve got a glassy start, the wind is almost nothing (Slight air at 3 mph), and the swell picks up to 3ft from the SSW with a solid 17-second period. The energy jumps to 565, which is moderate. This might not be huge, but for wave quality and clean conditions, this is the best we’ve got in the first week. The water is sitting at 60°, which is just about normal for the time of year here.

Now, as we move into the second week, things get more interesting. The morning of Wednesday, September 2nd, offers a glassy 4ft swell from the west, short period around 8 seconds, so a bit weaker energy at 388. But Saturday, September 5th, is the one to really circle on the calendar. That morning, we have a glassy 2ft SW swell with a long 18-second period and energy up at 748. This is a beautiful long-period groundswell rolling in with clean glass. That same afternoon, though—and this is for the experts only—a 10ft short-period WNW swell hits. That’s over 8ft, so it’s a big, powerful, messy wave with onshore wind. The beach and point setup will be a washing machine. Keep your wits about you if you paddle out. That afternoon energy is 1446, very strong, so it’s more of a sight to watch or a challenge for the brave.

The last real standout before the end of the window is Wednesday, September 9th, morning. Glassy conditions, 4ft swell from the west with a 9-second period, and energy at 527. Clean, solid, and consistent. By that afternoon, the swell drops back to 2ft with a very long 19-second period from the SW, but still glassy with calm wind—good for a longboard session.

Overall, we’ve got some gaps. The first few days are barely surfable. The best runs are on Sunday, August 30th morning, and then especially Saturday, September 5th morning, and Wednesday, September 9th morning. The big swell on the 5th afternoon is a real beast—only for the experienced. Expect some company, as Cox Bay can be busy sometimes. It’s a bit of a mixed bag, but there are some gems if you pick your windows carefully.

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.
