The Lowdown

Alright, grab a seat, let’s talk about Coxos. This is a reef break, pretty advanced, and it’s fairly consistent. The water’s sitting at about 69°F, which is spot on for the time of year, nothing unusual there.

The next 16 days are a bit of a mixed bag, to be honest. We’re looking at a long stretch of nothing much at first. From now through to the 14th of August, it’s a write-off – poor surf, mostly onshore or cross-onshore breezes, just a whole lot of nothing. It’s frustrating, but it happens. The swell energy is weak to moderate, with values around 100-200 (moderate wave energy), but it’s all messed up by the wind.

Things start to look a little more interesting around the 15th of August. The swell starts to push up, with heights around 5ft to 5ft, coming from the NNW. The energy is starting to build, hitting 400-plus (strong wave energy), but the conditions are still marginal. The wind is mostly onshore or cross-onshore, so it’s going to be a bit lumpy. It’s not a total loss, but it’s not a standout either.

The real standout, the one you’ve been waiting for, is the morning of Saturday, 16th of August. The swell jumps to a solid 7ft from the NNW, with an 8-second period, and the energy is pumping at 512 (very strong wave energy). The wind is glassing off from the NNW – that’s a light breeze, almost nothing. That’s going to be clean, powerful, and absolutely perfect for the advanced crew at Coxos. Just know that at 7ft, this is expert territory. The period is short, so it’ll be a bit crumbly, but the trade-off is clean, hollow waves. This is the best on offer, no doubt.

The following week, from the 17th to the 19th, it’s a bit of a drop-off. Swell hangs around 5ft to 6ft, but the wind is cross-on again, and the energy dips. The 20th of August has a promising morning with a 6ft swell from the NNW and a light, cross-off breeze from the SSW, which should keep it clean. The energy is 478 (very strong wave energy), so it’s got some punch. That’s a solid second option for the more experienced surfers.

After that, the 21st and 22nd see the swell dropping back down to 4ft to 5ft, with the wind swinging around. The morning of the 22nd of August looks like a decent paddle with a 4ft swell from the NW, a light cross-off, and an energy of 280 (moderate wave energy). It’s not the big stuff, but it’ll be clean and fun for the intermediate crew.

Right, that’s the long and short of it. The 16th of August is the one to circle. Keep an eye on the forecasts, but for now, that’s the best we’ve got.

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.
