The Lowdown

Alright, Rusty here. Let’s have a look at what’s cooking.

Honestly, for Coxos, this 16-day run is a tough one to call. We’ve got a stretch of pretty ordinary conditions to start, with only one day that really stands out as a proper score. The water temp is sitting at 69°, which is about average for this time of year, so nothing unusual there.

Right from the jump on Thursday the 30th of July, it’s a no-go. Swell is tiny at 2ft out of the NNW with a short period, and a cross-on wind making it choppy. That continues right through the first week. We get a bit more size on Saturday the 1st of August with chest-high waves around 3ft from the NNW, but the wind stays cross-on and the energy is moderate, so it’s lumpy and not worth getting excited about. Sunday the 2nd is similar, and the wind is onshore, so forget it.

The 3rd and 4th of August are marginal at best. Monday morning has a tiny westerly swell at 2ft with a 9-second period, but it’s light cross-on, so only just worth a mention. Tuesday morning on the 4th shows a 4ft swell from the west with a 9-second period, and the wind is onshore, but it’s still marked as marginal. By Wednesday and Thursday, we’re back to small stuff and messy winds.

Now, Friday the 7th of August morning shows a bit more push at 4ft from the WNW, a 7-second period, and the wind is onshore. The energy is getting up there, but it’s still rated as marginal because of the onshore wind. Lumpy.

It’s not until Monday the 10th of August that we start to see a real shift in size. The swell picks up to 8ft on Tuesday the 11th from the NNW, with a 7-second period and a big jump in energy. That’s some serious power, but the wind is a strong cross-on right through, making it fresh and lumpy. That continues into Wednesday the 12th with 8ft swell and very strong energy, but again, the wind is howling from the north at 22 mph cross-on, so it’s going to be a washing machine. This size is for experts only, and the wind is the killer. Thursday the 13th is similar, still big and messy.

Then, here it is – the one to circle. Friday the 14th of August morning at Coxos. Swell is a solid 5ft from the NNW, the wind goes completely glassy from the SW at just 3 mph. That is the moment. The energy is moderate. The period is only 8 seconds, so it’s windswell, but with zero wind and a clean surface, that reef could hold some nice, racy lines. The optimum swell direction for this spot is NNW, and that’s exactly what’s hitting. On Friday afternoon, the wind swings to a moderate cross-shore, so the window is the morning. Get on it. It’s a reef break that’s fairly consistent, but expect crowds here as it is a known spot. On that Friday morning, it’s the standout of the whole outlook.

After that, things look messy again, so that Friday morning is your best bet by a long way.

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.
