The Lowdown

Alright folks, Rusty here. Let’s get straight into it for this stretch of coast. Truth is, we’re looking at a pretty grim run ahead. The next sixteen days are a real struggle, with almost nothing worth paddling out for. The window starts with a tiny, marginal possibility on Tuesday the 4th of August, but honestly, it’s not one I’d get excited about.

Coxos (reef) is the only spot on the cards, and it’s an advanced reef break that’s fairly consistent. The water's sitting at 67°F, which is about normal for this time of year. The trouble is, the wind is almost always cross-onshore or onshore, and the swell is small and weak. Tuesday morning the 4th sees a tiny 3ft WNW swell with a 9-second period, but it’s cross-on with a light breeze and the combined energy is weak (135). It’s a pass for me.

From there, it’s a long, dry spell. Wednesday the 5th through Sunday the 16th of August is mostly a write-off. The swell stays small, mostly under 3ft, and the wind is a constant nuisance – cross-onshore from the NNW at 12 to 25 mph, making for choppy, lumpy, and messy conditions. The combined energy rarely climbs above moderate, and most of the time it’s weak (values like 73 to 393). There’s no standout quality, no clean windows, and certainly no reason to rush.

There is a little flicker of hope late in the period. On Sunday the 16th of August, the swell picks up to 5ft in the morning from the NW at 8 seconds, but it’s still cross-onshore and the rating is marginal. By Monday the 17th of August, the morning shows 6ft from the NNW at 9 seconds, with a gentler cross-onshore breeze and combined energy of 573 (moderate to strong). That’s the closest thing to a pulse we’ve got. But even then, the wind isn’t clean, and the period is average. It’s a big maybe for the hardcore crew who know the reef well.

Bottom line: this is a bleak outlook. There are no real standouts, no clean offshore days, and the swell is either too small or too wind-affected. I’d say save your energy and keep an eye on the forecasts – things can change.

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.
