The Lowdown

Alright, Rusty here. Let’s have a look at what Coxos has in store for us over the next couple of weeks.

Right off the bat, I gotta be straight with you – this is a tough run. We’ve got a long, frustrating stretch ahead. For the first week and a bit, from the afternoon of the 30th of July all the way through the morning of the 10th of August, it’s a blank. Nothing worth paddling out for. The swell is tiny, the wind is mostly on it or cross-onshore, and the energy is weak, often below 100. It’s a grim picture.

The first real glimmer comes on the morning of Monday the 3rd of August. Even then, it’s marginal at best. Coxos is seeing a little 2ft swell from the west, with a period of 9 seconds, and a light breeze from the WSW. The combined energy is a weak 76, and it’s just a questionable call. The wind is cross-onshore so it’s not going to be pretty. Not the one.

We get another little pulse on the morning of Tuesday the 4th of August. Swell bumps up to 3ft from the WNW, period still 9 seconds, and the wind is light and offshore from the NW. The energy climbs to a moderate 131, and the conditions might be tidally tricky, but it’s a marginal call. Still, with that clean offshore wind, this could be the best we see for a while. If you’re desperate, this is your window.

After that, it’s back to poor surf and choppy water until we hit the 10th of August. On Monday morning the 10th, the swell energy jumps to 203 from a 3ft WNW swell with a 9 second period, but the wind is a moderate cross-onshore breeze. It’s messy. The afternoon of the 10th is a little better, with a 3ft W swell, period 9 seconds, energy 214, and the wind is offshore from the NNW. That’s a clean look, but the swell is small and the period is short.

The 11th of August Tuesday morning brings the biggest energy of the forecast, at 212, from a 3ft NW swell, but the period is only 8 seconds and the wind is a fresh cross-onshore 19 mph from the north. That’s lumpy, choppy, and not worth the hassle.

Into the second week, we see a similar pattern. The morning of the 14th of August Friday has a bit more size – 5ft from the NW, but the period is a short 6 seconds, and the wind is a fresh cross-onshore 22 mph from the north. The energy is moderate at 152, but with that wind, it’s blown out.

Honestly, if you look at the whole 16 days, there’s no solid standout. The best shot is probably Tuesday the 4th of August morning with light offshore wind and a clean little 3ft swell, or maybe the afternoon of the 10th of August when the wind goes offshore again. Otherwise, it’s a long wait. The water temp is around 69°F, which is about normal for this time of year.

This stretch is a test of patience. It tends not to stay this poor for long, so keep an eye on the sky. But for now, give it a miss.

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.
