The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts for Coxos, and I’ve got to be straight with you—this isn’t a week to get excited about. The whole 16-day window is a bit of a struggle, with the wind and the swell not lining up for anything that’ll make you want to paddle out. There’s a real gap of poor conditions from the start, with no standout surf until the very end, and even that comes with a major caveat.
We kick off Monday, July 27th, with a tiny 4ft swell from the NNW, but the period is a short 7 seconds, and the wind is a light cross-onshore from the north. The combined energy is weak at 207, and it’s just marginal. Not worth the effort. The wind swings more onshore in the afternoon, and the swell drops to 3ft. Tuesday the 28th sees a little more size at 4ft, and the period stretches to 10 seconds, which is better, but the wind is still cross-onshore or onshore, and the energy is moderate at 333. Still, the scores are flat. This pattern—cross-onshore winds, short-period or weak swells, and poor surf quality—sticks around for days. The water temperature is about average for the time of year, so no surprises there.
The entire first week and into the second is a write-off. From Wednesday the 29th right through to Monday, August 10th, it’s a long stretch of poor surf conditions. The wind is mostly strong cross-onshore, often from the north or NNW, and the swell is either too small or too messy. The combined energy jumps up significantly on the 9th and 10th, hitting 397 on Sunday morning and 683 on Monday morning, with swell size reaching 7ft, but the wind is a fresh to strong breeze, making it lumpy and messy. That’s not a paddle-friendly setup; it looks more interesting for kite surfing than anything else.
The only real standout in the whole outlook is Tuesday, August 11th, but it’s for advanced surfers only. The morning session shows a solid 8ft swell from the NNW, with a period of 8 seconds. The combined energy is a massive 1046, which is very strong wave energy. The problem is the wind: it’s a strong cross-onshore from the north at 25 mph, making conditions messy and challenging. At that size, and with the short period, it’s a heavy, powerful wave that’s only for experts, and even then, the wind will make it a battle. As a heads-up, this is over a week away, so it’s promising but less certain. The break itself is a reef, exposed to the NNW swell, which matches the optimum direction, so the potential is there if the wind dies down, but as it stands, it’s a rough day.
So, to sum it up: the best on offer is the 8ft swell on August 11th, but with the strong wind, it’s not a clean, classic Coxos session. The rest of the forecast is a bust. The surf is inconsistent and the conditions are poor, but for this area, a blank run is more normal than not. Keep an eye on the forecasts, because things can change, but for now, I’d say leave the board in the car.
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.
