The Lowdown
Alright folks, Rusty here. Let’s break down what Cox Bay has in store for the next couple of weeks. It’s a slow burner, so keep your board in the car for a few days.
The first real shot of surf doesn’t show up until Friday the 11th of September. Before that, it’s all small, weak, and messy swells with cross-shore or onshore winds messing up the surface. The water temp is a normal 58°F, nothing crazy. On Thursday the 10th, we get a little bump in swell, but with a short period of 7 seconds and a moderate cross-onshore breeze, it’s going to be choppy and not worth paddling out.
The standout is Friday morning, the 11th of September. We’ve got a solid 6ft swell from the WNW with moderate energy (1059). The real magic is the glassy conditions – wind is almost nothing. This will give you clean, smooth waves at Cox Bay, a beach and point break that loves a little west in the swell. This one is for the experienced crew, as 6ft is too much for beginners. The period is short at 8 seconds, so expect pushy, roly-poly waves, but with that glass, it’ll be a blast. Later Friday afternoon, the swell drops to 3ft from the SW with a long 16-second period, and it goes glassy again – a perfect little bonus session for the late shift.
A few other mornings are worth setting an alarm for. The weekends of the 13th and 14th of September offer clean, glassy or clean conditions with small 2ft to 3ft swells. Nothing huge, but ideal for a longboard or a funboard if you just want to get wet and have fun.
Looking further out to the second week, there’s a promising but less certain event brewing for Monday the 21st of September. We’re looking at a big 8ft to 10ft swell rolling in from the SW. The energy numbers are huge (2280 and 3250), so this is a serious pulse. The wind is light and onshore, so while the power will be there, it might be a bit messy. This is expert-only territory for sure, with size over 8ft. Keep an eye on that one.
To sum it up: the first week is a scratch. The absolute best is Friday the 11th of September, morning session at Cox Bay. Don’t miss it. After that, keep the 21st of September in your notes for a big but sloppy groundswell if you’ve got the skills.
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.
