The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on offer at Coxos over the next couple of weeks.
Straight up, this is a tough forecast. We’ve got a whole lot of cross-onshore and onshore wind messing things up for the first week or so. The swell is there, but the conditions are just not cooperating. The water temperature is sitting around 69°, which is pretty much spot on for this time of year, so no surprises there.
The first real window of opportunity doesn’t arrive until Saturday, the 15th of August. That morning, we’re looking at a glassy start with the wind swinging light from the WSW. The swell is a solid 5ft, coming from the NNW with a period of 9 seconds, and the combined energy is pumping at 588 (moderate wave energy). It’s described as ‘expect very good surf conditions’ – that’s the standout. The break is a fairly consistent reef, and it’s best on a NNW swell direction, which is exactly what we’re getting. The water will be clean, the waves will have some punch, and for a reef break, the 9-second period is just fine. Just keep in mind, Coxos is an advanced spot, and with the swell size, it’s not for the faint of heart.
After that, Sunday the 16th of August morning is also looking glassy, with no wind and a 6ft NNW swell. The energy is still strong at 492 (moderate wave energy), but it’s a shorter period of 8 seconds. That’s still a good morning, but the Saturday morning has the edge for overall quality.
From the 17th onwards, the wind picks up again, turning cross-on and ruining the surface. The swell hangs around, but the chop and bump make it a real struggle. There’s a big jump in energy on the 21st of August with a 7ft to 8ft NW swell, but the wind is a fresh cross-onshore, smashing it up. That’s a write-off for paddle surfing, but it might look interesting for the kite surfers.
So, the bottom line: if you’re keen, circle Saturday the 15th of August morning. That’s the pick of the fortnight. The Sunday morning before it cleans up is also a solid option. After that, it’s a waiting game.
Rusty.

Information about the Coxos Surf forecast
The above surf forecast table for Coxos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Coxos can be found by selecting the local surf guide option on the grey menu. Our Coxos 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 (Coxos) 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 Coxos 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.
