The Lowdown
Alright, this is a tough one to call. Look, I’ve been staring at the charts for Coxos, and for the first week and a half? It’s grim. We’re talking a real dry spell. From Monday the 3rd of August right through until Friday the 14th, the wind is a constant problem – mostly a cross-on shore breeze, and when it’s not that, it’s onshore. The swell is small, weak, and the period is short. It’s just choppy and messy. The combined energy barely breaks into triple digits, and when it does, it’s just a lot of wind chop. There’s nothing to recommend. A real blank run for the area.
Then, we get a flicker of hope. The real standout is the morning of Saturday the 15th of August. Conditions look like they could finally come together. The wind will be glassy – that’s the first time we’ve seen that in the whole window – and the swell is jumping up to 7ft from the NNW. The combined energy is a solid 374, which is a proper moderate pulse with some push. This is the one to have your eye on. That morning window is the absolute best on offer, clean and with some size.
Later that weekend, the 16th and 17th, the swell really fires up. We’re looking at 8ft from the NNW on the Sunday morning, with a massive 864 combined energy. That’s a strong, powerful swell. But the wind turns onshore or cross-shore again, so it won’t be the clean session the Saturday morning is. The period is short at 7-8 seconds, so it’s a windswell—it’ll be a bit lumpy and raw. At 8ft, this is for experts only. The 7ft on Monday morning is still hefty, but with the onshore wind, expect it to be a battle.
All in all, the Saturday morning glass-off is your one bright spot. Get in the water then.

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.
