The Lowdown
Alright, surfers, Rusty here. Let’s talk about what’s on the menu for Coxos over the next couple of weeks. Gotta be straight with you, this is a tough stretch to start.
Right now and for the first couple of weeks, the surf is looking pretty poor. We’ve got a long flat spell and some messy conditions. The first real chance for a surf isn’t until Thursday morning, the 30th of July. That’s over two weeks of waiting for something decent.
From Wednesday the 15th through to Wednesday the 29th, the waves are tiny, often below 2ft, and the wind is mostly cross-onshore or blowing straight onshore. The water temp is about 66°, which is around average for this time of year, so that’s not the problem. The problem is a total lack of any real, rideable swell. The combined energy is weak, mostly well under 100, and often in the double digits. It’s just not doing anything.
Now, Thursday morning the 30th of July finally brings a flicker of hope. We’ve got some early glassy conditions at Coxos, with a 5ft swell from the NNW. The energy bumps up to 232, which is a sign of life. The period is only 7 seconds though, so it’s a short-period windswell, not a long rolling groundswell. Still, glassy conditions on a reef break with head-high sets? That gets my heart pumping. It won’t be clean for long though, as the afternoon brings a risk of thunderstorms and the wind swings around to the SW, getting messy.
Honestly, that Thursday morning window is the only standout. It’s the one to watch for a quick, clean session. The rest of the forecast is basically write-offs for a paddler. The swell that builds around the 24th to 26th is 4ft to 4ft, but it’s short-period (6 seconds) and blown out by strong onshore winds. That setup is honestly more interesting for the kite surfers than for anyone with a paddle.
There’s really no other spot to talk about here, just Coxos. A two-week wait for a few hours of glassy 5ft surf is a tough pill to swallow, but that’s the reality.
Stay tuned, forecasts can change around that second week window.
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.
