Alright, Rusty here. Let's break it down.
Honestly, the next couple of weeks are looking like a total bust for surf around here. We've got a long, grim run of tiny, weak, and messy conditions. Coxos is the only spot mentioned, and it's going to take some serious patience.
The main problem is the wind. It's almost constantly cross-onshore from the north or northwest, and that just rips the guts out of any potential wave. Through the first week, the swell is small, mostly in the 1.0ft to 2ft range, with periods under 10 seconds. You’ll see a tiny bump on Saturday 5th, but the energy is still weak (156 combined swell energy). The water is at 66°F, which is pretty normal for July, so at least you won't be cold while you're scratching for nothing.
Then we hit a proper dead zone from the afternoon of Sunday the 6th right through until Tuesday the 15th. For eight days, the surf quality is rated as poor or marginal. There's a small pulse on Sunday 12th with 3ft swell from the NW and a period of 9 seconds, which bumps the energy up to moderate (253-274), but that wind is still cross-onshore from the west, ruining any chance of a clean wave.
The real stand-out, and probably the only window worth getting excited about, shows up on Thursday the 16th. It's a long way off, so don't hold me to it, but the models are hinting at something. On Thursday morning we get a 1ft NW swell, but the period jumps to 12 seconds, and the energy is back up to 111. The wind looks lighter and more variable. Then on Thursday afternoon, it improves a little more with a 2ft NW swell, an 11-second period, and 125 combined energy. The wind goes offshore from the NW at 12 mph. That’s the key. If that wind holds, it could be a rare clean session on the low-tide banks.
Later on, Saturday the 19th and Sunday the 20th, the swell size actually picks up to 5ft, but with a short, weak 6-second period. The combined energy hits 247-260 (moderate), but with a strong breeze from the north, the whole thing is going to be a messy, lumpy onshore disaster. For kite surfers, that's probably fun, but for a paddle surfer, it's a total loss.
So, to wrap it up: the first week is a wash, the second week is mostly a wash, but keep an eye on Thursday 16th. That’s the one session that has any chance of being clean and worth the paddle. Don't expect anything before that.

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.
