The Lowdown
Alright folks, let's break down this 16-day stretch. I gotta be honest, there's a big ol' dry spell at the start. We're looking at almost a week and a half of nothing special before we get a real chance. The first day worth talking about doesn't come until the 9th of August. The water temp is about what you'd expect for this time of year.
Coxos is our only player here – a reef break that likes the north-northwest swell. It can get a few people out there, so don't be surprised if you got company. For the whole run from the 29th of July through the 8th of August, it's a wasteland. The wind is constantly cross-on or onshore from the north-northwest, making the surface a mess. Swell heights are tiny, barely breaking a few feet, and the energy is weak to middling. Just leave your board in the car.
Finally, on the morning of the 9th of August, things calm down. We get a light cross-offshore breeze from the east-northeast. The swell is only about 4ft from the west with an 8-second period, but it's clean. The energy is moderate. You can get wet, but don't expect to be writing home about it.
The real standout, the one you want to circle on the calendar, is the morning of the 10th of August. The swell jumps to about 5ft from the northwest. Still a short-period swell, so it'll be a bit crumbly, but the energy kicks up good and solid. The wind is light from the north-northwest, just putting a tiny crinkle on the surface. It's the cleanest, biggest combo we'll see all forecast. Grab it before the afternoon wind gets on it and messes it up.
The 11th of August sees a big pulse to 7ft from the north-northwest. That's expert water with short-period chop and onshore winds – not for the faint of heart. The days after that drop in size but stay blown out. So, the call is simple: wait it out, then make a beeline for Coxos on the morning of the 10th.

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.
