The Lowdown
Alright crew, Rusty here. Let's get down to brass tacks on this 16-day forecast.
It's a rough one. The whole stretch is looking pretty poor for Coxos. The swell is often coming from the right direction, NNW, but the wind is a killer. It's almost always cross-onshore, chopping everything up. Not a single day is looking clean.
The first bit of surf to talk about is on Tuesday morning, 28 July. We've got a 4ft swell from the NNW, with a 10-second period, giving us a moderate wave energy of 333. The water is 69°, which is about normal. But the wind is a light cross-onshore, and the report says "marginal." It's a tough start.
From there, it's a long, miserable run. The swell drops, and the wind stays onshore or cross-onshore all through the end of July and into the start of August. Wednesday, Thursday, Friday, the weekend – it's all "poor surf conditions." The wave energy falls into the 70s and 80s, and the wind keeps it choppy.
Then, on Friday, 7 August, we get a solid spike. The swell hits 8ft from the NNW, with an 8-second period, and the combined energy cranks up to 743 – that's a strong pulse. But the wind is a fresh cross-onshore at 19 mph, making it "lumpy." For a reef break, that's a washing machine. This size is only for the experts, and with that wind, it's a struggle.
This big, lumpy energy sticks around for the weekend of 8-9 August, with waves between 5ft and 8ft, all with the same fresh cross-onshore wind. The energy is in the 500-800 range, so there's plenty of power, but the quality is terrible. It's a kite surfer's dream, but a paddle surfer's nightmare.
The energy fades into the second week, with waves dropping back to 2ft to 5ft, but the wind stays stubbornly cross-onshore from the north. The swell and wind are just not on the same page.
Honestly, there's not a single standout day here. The wind ruins everything. If you're really keen, the morning of Tuesday, 28 July is the least terrible option, but it's still a gamble. The rest of the 16 days? I'd hang the board up and wait for a better forecast. The ocean's just not giving us a break.
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.
