The Lowdown

Right then, let’s have a look at what Cox Bay has cookin’ over the next couple of weeks.

We’ve got a bit of a slow start, but things are shaping up. The water temp is sitting about average for this time of year at 59°, so nothin’ weird going on there.

The first real standout is Thursday, the 10th of September. We’re looking at a solid 7ft WNW swell, but here’s the catch – period’s short, only 8 seconds, so it’s a bit of a windswell. Still, the combined energy is pumping at 1222 (moderate), and the wind is glass first thing in the morning. That means clean, pushy waves. At over 5ft, this is one for the experienced crew; beginners might find it a handful. Cox Bay is a beach and point setup, so with that short period, expect some punchy, pitching waves.

Friday the 11th is a beauty. Morning has a clean 3ft SW groundswell with a long 17-second period, and a light cross-off breeze. The combined energy is 647 (moderate). That long period will see the waves jackin’ up nicely, with good shape and longer lulls between sets. The afternoon goes glassy with a 5ft W swell, which is just perfect. This is the pick of the week for clean, lined-up waves.

Saturday the 12th and Sunday the 13th hold some small, clean swell in the 3ft range, with light winds and glassy or cross-off conditions. Nothing to get too worked up about, but enough for a longboard or a funboard to have a cruise.

Now, there’s a flat spell from around Monday the 14th through to Thursday the 17th. Tiny, weak surf with poor conditions – not worth the paddle out.

Things get interesting again on Saturday the 19th. We’ve got a 8ft WNW swell rolling in, but it’s accompanied by light rain and a moderate offshore breeze from the ESE at 16 mph. The combined energy is 967 (moderate). This size is on the border of expert-only territory.

But the real standout of the whole outlook is an absolute bomb on Tuesday the 22nd. Cox Bay will see a 10ft W groundswell with a nice 12-second period, and the combined energy is a whopping 2751 (strong). The morning is glassy. This is huge, powerful surf. Period over 11 seconds means proper groundswell, but at 10ft, this is strictly for the experts only – the experienced, waterman types. The point and beach setup should offer some heavy, walling waves, but with that size, the beach break sections might close out. It’s a long way out, so keep an eye on it, but it looks promising.

Enjoy, and don’t get smashed.

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.
