The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this outlook for Coxos is a tough one. The entire 16-day window is basically a write-off for any decent paddle surfing. Every single record shows “poor surf conditions” with a score of zero out of ten for the first two weeks. There’s a long gap of flat or messy days starting now and stretching all the way to the end of the month. The only real glimmer, and I mean a distant glimmer, shows up right at the very end on the 31st of July, but even that’s not a green light.
Let’s run through it. From Thursday the 16th all the way through to Thursday the 30th, it’s a desert. Swell heights are tiny, mostly under 3 ft, and the wind is almost always onshore or cross-onshore, blowing from the WNW or NNW. That’s not the clean offshore direction this reef spot needs. The combined wave energy is weak, rarely cracking triple digits, and when it does – like on the 20th and 21st with 163 and 201 – the wind is still junk. The water temp is sitting at 66°, which is about 1° below the long-term average, so pretty normal for this time of year.
The only day that even gets a mention is Friday the 31st of July. We’ve got an 8 ft swell from the NNW, with a solid 12-second period. That’s real groundswell energy, and the combined energy reading is a massive 1903, which is strong. But here’s the catch – the wind is cross-onshore from the NNE in the morning, which is a shame. The score is only a 3 out of 10, called “marginal.” This is a top-tier reef break for experts, and with that size, it’s expert-only territory. The swell direction is NNW, which is the optimum for Coxos, so the potential is there, but the wind will mess it up. The afternoon turns onshore too, with an 8 ft, 11-second swell and a score of 2. Not worth the paddle.
Honestly, if you’re looking at this stretch, the setup is more interesting for kite surfing than paddle surfing. The consistent onshore winds and building swell will give kite riders something to play with, but for a surfer? There’s nothing to recommend. It’s a blank run, and for this area, that’s not unusual. Forecasts can change, but as it stands, I’d save the wax.
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.
