Table - best surf conditions forecast for Coxos over the next 16 days.
Right then, let’s have a look at the 16-day crystal ball. The first spot on the list and really the only game in town for this stretch is Coxos, a reef break that’s exposed to the swell and likes an optimum direction from the NNW.
Right off the bat, for the first week, it’s pretty grim. The swell is tiny and the wind is all over the shop. Tuesday the 7th through to Monday the 13th is a write-off; the waves are just too small and crossed-up to bother with. There’s about a week of flat, poor conditions where you’d be better off waxing your board and watching the horizon.
Water temp is sitting at about 67°, which is bang on average for this time of year, so no surprises there.
The real interesting bit turns up towards the end of the run. On Monday the 20th of July, things start to wake up. We get a jump in swell height to 5 ft, coming from the NNW, but with a short, choppy period of only 7 seconds. The combined energy is moderate at 189, but the wind is screaming from the north at 22 mph, cross-on. It’s going to be lumpy and messy – more of a kite surfing session than a paddle into tidy waves. The following days, Tuesday the 21st and Wednesday the 22nd, keep that energy up, with combined energy hitting 270 on Tuesday the 21st (moderate to strong), but the wind stays strong and cross-on. Swells of 5 ft and 6 ft are on the table, but with that wind and short period, it’s a tough, blown-out affair. Honestly, for the entire 16-day window, there isn’t a single standout session. The forecast confidence for the second week is low, but as it stands, you’d be waiting a long time for a clean wave.

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.
