The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Alright, we’re lookin’ at a pretty grim start, to be honest. The first week is a real struggle with poor conditions and not much to get excited about. We’ve got a bit of a dry spell, with no real quality surf on offer until well into the run. The first real chance of anything decent doesn’t show up until Tuesday, August 4th, and even then it’s just a glimmer.
The standout, and really the only window for a proper surf, is shaping up for Sunday, August 9th. The swell is gonna be a solid 6ft from the NW with a period of 10 seconds, which is a nice groundswell. That’s a lot of energy pouring in, with a combined energy reading of 739 (moderate). The wind is light out of the NW in the morning, which is a straight-on offshore for Coxos. This is a high-performance reef break, so that long-period NW groundswell will wrap in beautifully. It’s a spot that’s ‘fairly consistent’ but can be a bit fickle, so when it lines up like this, it’s magic. The water temp is about average for the time of year, nothing weird. Just keep in mind it’s an advanced spot, and with the swell size it’s in the expert zone. The crowds are ‘often’ here, so expect some company.
Earlier in the week, on Tuesday, August 4th, there’s a brief moment of hope. The morning session shows a tiny 3ft WNW swell, but the wind is glassy – a light WNW breeze, almost nothing. That’s a rare treat. The combined energy is 125 (moderate), but it’s small. The period is 8 seconds, so it’s a short period swell that won’t have much punch, but it’ll be clean as a whistle. You’d be on a longboard or a funboard, just enjoying the stillness.
After that 9th burst, things get messy again. The wind picks up strong from the N and NNW, turning the ocean into a lumpy, choppy mess for the rest of the second week. The swell hangs around at 5ft to 7ft, but with those strong cross-onshore winds, the quality is shot. The setup looks more like a kite-surfing zone than a paddle-surfing one for those days.
So, to wrap it up: suffer through the first week, mark your calendar for Sunday, August 9th for the main event, and maybe sneak a glassy session on Tuesday, August 4th morning if you’re desperate for a clean paddle.
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.
