The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right off the bat, I gotta be straight with you – the first week is a tough one. We’re looking at a real slow start with tiny, weak swell and messy onshore winds day after day. From Friday the 17th right through to Sunday the 20th, the surf is pretty much flat and poor. The wave energy is laughable, sitting well under 100 (30 to 89) with a short-period windswell. Not worth paddling out for.
Things start to change a little around Monday the 21st. We get a bit more size, around 3 ft to 4 ft from the NNW, and the energy picks up to moderate levels (154 to 252). The wind is still cross-on, but by Tuesday afternoon we get a *marginal* call – that’s the first real glimmer of hope. Still, the quality is not there yet.
The best of the bunch, and the only real standout in this outlook, shapes up on Monday the 27th of July. The swell bumps up to 8 ft from the NNW, with a period of 9 seconds and a solid combined energy of 1043. That’s strong wave energy. The wind is a gentle cross-onshore, which at Coxos (a reef break) can still offer some clean lines. It’s a little raw and the tide might be a factor, but for the experienced surfer, this is where you want to be. That’s expert territory, mind you – 8 ft is no joke for beginners.
The water temperature is about average for this time of year, so no need to worry about a thermals.
The Tuesday the 28th and Wednesday the 29th hold similar size (8 ft to 8 ft) but the wind gets stronger and more cross-on, making it lumpy and messy. Not the same quality as that Monday window.
So, to sum it up: the first week is a write-off, but that Monday the 27th of July is your best bet. Mark it in the calendar. Expect a crowd at Coxos, as it’s often busy, but for a quality reef break with a solid NNW groundswell, it’s worth the company.
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.
