The Lowdown
Alright folks, Rusty here. Let's get into it. To be honest, looking at the entire 16-day window, this is a pretty quiet stretch for us. The surf is small, the wind is mostly junk, and we’re just not getting any clean, rideable waves coming through. The water is sitting at 68°F right now, which is about average for this time of year – nothing to write home about, but you won't need a thick suit.
The first real chance to even paddle out isn't until Tuesday the 4th of August, and even then it's a marginal call. It’s a long wait through the weekend with nothing but onshore and cross-onshore winds messing up tiny, weak waves. The combined swell energy is pretty weak to moderate at best, peaking at 169 (moderate) early on but dropping off fast.
Here’s the lowdown on the only real standout, and it's a long-range one. On the morning of Wednesday the 12th of August, Coxos (reef) is looking like our best bet. We’ve got a glassy morning with a light breeze, and the swell is 2ft from the WNW. The swell period is 9 seconds, so it’s a short-period wind swell, not a groundswell. The energy is moderate at 179, but the combo of a clean, glassy surface and a small, manageable wave makes it the most user-friendly option in the entire outlook. The swell direction is off from the optimum NNW, so it won't be firing, but for a wave, it’s the only one that’s surfable and clean. The next morning, Thursday the 13th, we see a slight bump in size to 5ft from the NNW, but it's onshore and a bit messy, albeit with a longer period of 8 seconds that might offer a bit more push. However, the wind is light, making it a marginal but possible session.
After that, the wind really picks up. By Friday the 14th, we’re looking at a bigger swell – 6ft from the NNW – but with a strong 25 km/h cross-onshore wind, it’s going to be a messy, choppy mess. The energy is strong at 594, but it's blown out. That pattern of strong, cross-onshore wind and lumpy conditions continues right through to the end of the forecast on the 16th, with the swell dropping back to 2ft. So, for a risk-it-all session, the morning of the 12th is your window. The rest of the period is a write-off for a decent paddle.

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.
