The Lowdown
Alright, let’s talk in feet and Fahrenheit.
First up, Coxos. It’s a reef break, and it’s a bit of a mixed bag for the next couple of weeks. Water temp is about 68°, which is right where it should be for this time of year.
The pattern starts quiet. Saturday morning the 22nd shows a 5ft NNW swell with a very long 10-second period, and it’s nearly glassy. The energy is moderate (432), but the forecast says it’s marginal. The light wind is a plus, but it’s not a standout.
Sunday the 23rd brings a bigger pulse – 6ft from the WNW, 11-second period, solid energy (767) – but the wind is a fresh 35 km/h cross-offshore from the south. The waves will be clean, but fighting that wind won’t be fun.
Monday the 24th gets ugly. 8ft of short-period WSW swell with cross-shore winds. Stay out of the water.
Tuesday the 25th morning is your best bet. The swell drops to 4ft from the WNW, period is short at 7 seconds, but the wind is glassy – just 5 km/h from the west. The energy is weak (153), but for a clean, small session on a reef, you can’t beat it. Crowds are often, so expect some company, but it’s the only truly clean window in the whole outlook.
From Wednesday the 26th all the way through to Saturday the 6th of September, it’s a long stretch of poor conditions. Cross-onshore winds, lumpy seas, and choppy waves dominate. There’s a big spike on Friday the 28th of August – 8ft from the NW with a 12-second period and very strong energy (1674) – but the wind is cross-onshore at 25 km/h, making it a powerful, messy wave for experts only.
The one to aim for is Tuesday morning, the 25th of August. Small, clean, glassy. The rest is a write-off.
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.
