The Lowdown
Alright folks, Rusty here. Let’s get stuck into what’s on the cards for the next couple of weeks.
We’ve got a pretty telling run ahead. The only real window of quality is right at the very start, and it’s a short one. After that, we’re staring down a long stretch of messy, wind-affected days that just won’t deliver. There’s a gap of several days with no real options, and then the second week brings some serious size, but with brutal winds that ruin it for paddle surfing.
The standout is Monday morning, July 27th, at Coxos. It’s a reef break, exposed to the swell, and it’s firing. The water temp is sitting at 70°, which is pretty average for this time of year, nothing weird going on there. We’ve got a 4 ft swell from the NNW with a period of 7 seconds, but the combined energy is sitting at 207 (moderate). The real magic here is the wind: a glassy NNE breeze at just 3 mph. That’s going to put a mirror finish on it. The waves will be clean as a whistle. This is the one to point your board at. Keep in mind, it’s an advanced spot and it can get crowded, so expect some company.
The same morning, the offshore wind is from the SE, which is exactly what Coxos needs. It’s fairly consistent here, so you’ll get your share of waves.
By Monday afternoon, the wind swings onshore from the NW at 9 mph, and the quality drops off. That’s the end of the good stuff.
From Tuesday, July 28th, right through to the second week, it’s a write-off. The wind is consistently onshore or cross-onshore, and the wave state is described as poor, choppy, or lumpy. The swell builds, but it’s a mess. By the time we hit August 9th and 10th, we’re talking about serious 8 ft swell from the NNW with a period of 8 seconds, and combined energy readings over 900 (strong to very strong), but it’s being thrashed by 19-22 mph cross-onshore winds. That’s a washing machine. For the experienced crew, that’s more of a kite-surfing setup than a clean paddle session.
So, the call is simple: if you’ve got Monday morning, July 27th, free, get to Coxos. It’s the only true standout in the whole 16-day window. Everything else is a pass.
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.
