The Lowdown
Hey, it’s Rusty. Look, I’m not gonna sugarcoat it – this 16-day forecast for the area is a real heartbreaker. We’ve only got one spot in the game, and that’s Coxos, a reef break that likes advanced surfers and needs the wind to play nice. The water temp is about what you’d expect for this time of year, nothing weird there.
Starting Monday, August 3rd, it’s a total wash. We’re looking at 2 ft swell from the west, weak energy (73), and a 9 mph cross-shore wind. It’s choppy and poor.
Tuesday the 4th is barely a step up. A 3 ft WNW swell shows up, energy is weak at 135, and the wind is still cross-onshore at 6 mph. The afternoon turns onshore. Just leave it.
From Wednesday the 5th to Friday the 7th, the swell builds to 5-6 ft from the NNW, with moderate to strong energy (338-521). But the wind howls at 15-19 mph cross-onshore. It’s lumpy, choppy, and ugly. That’s not clean Coxos.
The weekend of the 8th and 9th, it fades to 2-3 ft slop with energy dropping to 64-158. Onshore and cross-onshore winds keep it messy.
Monday, August 10th through Wednesday the 12th, the swell is tiny (1-2 ft), energy is low (47-244). The wind does lighten up to a 6 mph breeze on the 11th morning, but the swell is too small to bother with.
Thursday the 13th and Friday the 14th, the swell jumps back to 6 ft from the NNW, energy strong at 448. But the wind is 15 mph cross-onshore. It’s got power, but it’s blown to bits.
Saturday the 15th is the same story – 4-5 ft swell, onshore wind, energy around 293-412. Every single day from August 3rd through the 18th is stamped “poor surf conditions.” Even the longer period groundswell that shows up gets wrecked by the wind.
So what’s the call? If you’re an expert at Coxos and you just want to get thumped, the 6th to the 8th and the 14th offer the most size, but you’ll be battling a strong onshore wind. After the 15th, it’s just 1-2 ft junk with a 25 mph breeze and no energy. That’s a two-week dry spell, plain and simple. Things could change, but right now, I’d hang it up.
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.
