The Lowdown

Alright, Rusty here again. Look, it’s a tough run of surf ahead, no way around it. The first real chance to get wet isn’t until Tuesday, August 11th, so you’ve got a full week of waiting before anything even gets close to decent.

From Monday, August 3rd through Monday, August 10th, it’s all small, weak, and wind-affected. Waves are tiny, mostly 0.4 to 0.8 feet, with weak energy and cross-onshore winds. The water is about 68°, normal for the season.

The only break that shows a pulse is Coxos (reef) . On Tuesday morning, August 11th, there’s a 0.9 foot swell from the NNW with a period of 11 seconds – a proper groundswell that should give the waves some push. The swell energy is moderate at 283. The wind is a light breeze from the north at 9 mph, but it’s cross-onshore, so the face might have a few bumps. The direction is perfect for Coxos, matching its optimum.

Still, it’s a marginal day, not a classic. Crowds are common here, so expect company. The reef should handle that 11-second period well. This is really the only window in the whole 16 days worth mentioning.

After that, from the 12th to the 18th, we get bigger numbers – waves up to 6 feet by the 17th and 18th – but the period drops to 7 seconds (short period windswell) and the wind is fresh and cross-onshore. It’ll be lumpy, choppy, and messy. Energy climbs to 376, but without clean wind or a long period, it’s just a washing machine.

So, to sum it up: keep your eyes on Tuesday morning, August 11th at Coxos for a possible quick session. The rest of the forecast is a write-off. Things can change, but right now it’s a long, quiet stretch.

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.
