The Lowdown

Alright folks, Rusty here. Let’s look at what’s shaping up for Coxos. This forecast is a bit of a tease, honestly. We’ve got a long stretch of nearly nothing to start, and then a potential window of proper waves way down the line.

Right now, the water’s sitting at 69°F, which is about average for this time of year, nothing to write home about.

The first week is pretty grim. From Sunday the 19th all the way through to the end of July, the conditions are mostly poor. We’ve got onshore winds and weak, short-period swell. The combined swell energy is almost always in the weak to moderate range, and the period hangs around 6 or 7 seconds. That’s just windswell junk. Don’t even bother paddling out for the first week unless you want a frustrating session. The wind is mostly from the NW and NNW, blowing right onshore, making everything a mess.

We do see a slight uptick in size around the 28th of July, with swell hitting 7ft, but the wind is still howling onshore at 18-22 mph. The energy jumps into the moderate range, but the quality is still poor. Not worth it.

Now, here’s where it gets interesting. The real standout is the morning of Thursday, July 30th. The forecast shows a 7ft swell from the NNW, with a 9-second period, pushing a combined energy of 770 (moderate wave energy). But the key is the wind: a light 9 mph breeze from the south, which is offshore for Coxos. The file says it’s "clean" and "expect very good surf conditions." That’s the window. A solid, clean groundswell on a reef break. Keep in mind that 7ft is on the bigger side, so this is for the experienced crew.

We then have a bit of a drop-off into the weekend, with clean conditions again on the morning of Sunday, August 2nd, with glassy winds from the WNW at just 3 mph. The swell is a smaller 4ft from the NNW, with an 8-second period and energy of 226. It’s a more manageable size, and the glassy conditions will make it silky smooth. This is a solid backup option.

So, to sum it up: don’t bother with the first week. The real targets are the clean, offshore morning on Thursday the 30th for the bigger, more powerful waves, and the glassy morning on Sunday, August 2nd for a cleaner, smaller session.

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.
