The Lowdown
Alright crew, Rusty here. Let’s talk about Coxos. It’s a reef break that’s open to the swell, and it’s a pretty consistent setup that doesn’t mind a bit of size. The water’s sitting at 69°, which is about a degree and a half warmer than usual for this time of year – a nice little gift.
The first part of this run is a real drag. From Monday the 20th all the way through the end of the first week, it’s a total bust. Tiny waves and the wind is just garbage. Don’t even think about it until later. There’s a dry spell of about a week for any decent surf.
The first real gem shows up on the morning of Tuesday the 28th. That’s the one. Swell is a solid 7 ft from the NNW, with a period of 9 seconds, packing some serious punch. The combined energy is a solid 635 (moderate to strong), and the wind is a light 6 mph cross-offshore from the SSW. That’s clean, that’s silky. The waves are going to be well-shaped and powerful. This is the session to plan for. The afternoon gets messy with a cross-shore wind, so you’ve got to be on it early.
Wednesday the 29th morning is still a good call. Swell drops to 4 ft from the NNW, but the wind is still light cross-offshore. The energy is 227 (moderate), and it’ll be clean. A solid follow-up session if you missed the peak.
After that, it fades. Thursday the 30th and Friday the 31st have smaller, weaker swell and choppy wind. Saturday the 1st of August and Sunday the 2nd are pretty much a washout with strong onshore winds and lumpy conditions. There’s a late pulse of bigger swell on Monday the 3rd and Tuesday the 4th of August, with swell hitting 8 ft and energy up to 813 (strong), but the wind is fresh cross-onshore, making it lumpy and ugly. Real shame, because the size is there for the experts, but the wind just butchers the surface.
So, bottom line: if you’re keen, Tuesday the 28th morning is the absolute winner. Get it while it’s clean. The rest of the window is either too small, too windy, or both.
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.
