Alright folks, Rusty here. Let’s have a look at what’s on the cards.

Right, the outlook for Coxos is a bit of a tough one. We’ve got a long dry spell ahead. The first proper recommendation doesn't even appear on the horizon for a while. There’s a massive gap of almost no surf worth paddling for. The good news is that this spot is a fairly consistent reef break, so when it does turn on, it can be special. The water temperature is sitting at 66.7°, which is pretty much average for this time of year, so no surprises there.

We start off this Wednesday, July 8th, with nothing doing. A small 2.9ft swell from the NNW is getting chopped up by a 12 mph cross-on wind, and that combined swell energy is a weak 65. It’s a write-off. Thursday and Friday are much the same story – tiny, weak swells and onshore winds. You’d be wasting your time.

Saturday the 11th morning shows a glimmer. The wind goes light, almost glassy, with a 1.3ft NW swell at a long 11-second period. The energy is still just 92, so it’s marginal, but that clean surface could give you a few slippery ones if you’re desperate.

The real story here, the one true standout, is that stretch from Sunday July 19th through to the end of the forecast. We’ve got a solid pulse of NW swell. By Sunday morning the 19th, we’re looking at 6.2ft from the NNW, with the combined energy jumping to a strong 419. That’s proper. By Monday the 20th morning, it’s hitting 8.2ft from the NNW, and the energy is a very strong 976. This is expert territory now, as it’s well over 8ft. The only catch is that every single session in that period is plagued by cross-on winds, mostly a fresh 19-22 mph from the N or NNW. It’s gonna be lumpy, bumpy, and pretty raw.

For a break that loves a clean offshore from the SE, having a howling cross-on is a real shame. The waves will have power, but the surface will be messy. For a reef like Coxos, a long-period groundswell like this (period 8-9 seconds on those bigger days) will bring a lot of energy, but with the wind direction all wrong, it’s not going to be a classic. Honestly, with that much swell and those strong onshore winds at a reef setup, it’s looking more interesting for a kite session than a clean paddle session.

The pick of the bunch, if you’re an expert looking for power and don’t mind a challenge, is the morning of Monday July 20th. Swell is a solid 8.2ft from the NNW, energy is a massive 976, and although the wind is a cross-on 16 mph from the north, that’s the lightest the wind will be during the whole big swell window. It’s a beast, but it’s the only real option.

Stay safe out there.

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.
