The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
To be straight with you, it's a grim stretch ahead at Coxos. We're looking at a solid 16-day window with barely a whisper of a decent wave. The first week is a write-off, with nothing but onshore slop, teeny tiny swell, and that persistent NNW wind ruining any chance of a clean face. The water is a warm 68°, bang on average for the time of year, but that's about the only thing that's normal.
The second week doesn't get much better. The swell does start to build, but it brings nothing but wind and chop. By the 27th of July, we're seeing 6ft to 7ft of swell, but it's still onshore and messy. The energy starts to ramp up, hitting moderate levels (449) by Monday morning, but it's all for nothing. The real downer is the 28th and 29th of July, when the swell jumps to 8ft. That's too big for beginners and would be for experts only, but the wind is howling a strong cross-onshore at 28 mph, and the combined energy is through the roof at 1022. It's a total mess. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
The only glimmer of hope, and I mean a tiny glimmer, is on the 30th of July. The morning shows an 8ft swell from the NNW with a period of 9 seconds, and the wind has eased right off to a gentle 9 mph cross-onshore. The energy is still very strong (1004), but that lighter wind might just tidy it up enough for a few. The forecast calls it "marginal". It's a long way out, so don't bank on it.
There's nothing to recommend here. A blank run like this is more normal for the area when the wind doesn't play ball. Keep the board in the car, but leave the wax at home.
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.
