Alright, grab a coffee and listen up. Rusty here. I’ve been staring at the charts for Coxos, and I’ve got to be straight with you – it’s a rough run ahead. We’re looking at a solid 16-day window, but honestly, there’s not a single truly good session on the cards. The forecast is a long stretch of meh, with a lot of "poor surf conditions" stamped all over it. The only real consolation is Coxos is a fairly consistent reef break, so it’s more of a waiting game than a total write-off.

The first faint glimmer comes on the morning of Sunday the 12th. We’ve got a tiny 2 ft swell from the NW, with a period of 9 seconds. The water is a bit colder than usual for July at 65°, but the real killer is the light S breeze. It’s a cross-offshore wind, so the surf is clean, but the wave energy is weak (154). It’s surfable, but only just, and definitely not worth getting excited about. The afternoon turns into a mess with a moderate cross-shore wind.

Monday the 13th is more of the same – 2 ft, weak energy. The morning has a light cross-offshore, so it’s clean, but it’s flat. The rest of the week is a write-off: Tuesday through Thursday are all cross-onshore winds and tiny, weak swell. The energy readings are in the dumps, barely cracking 100.

Now, here’s where it gets a bit cruel. From Friday the 17th through to the following Saturday, the swell actually picks up. We’re looking at 4 ft to 7 ft from the NNW, with moderate to strong wave energy (in the 100s and even 400s by the 24th). But the wind is a disaster. It’s a relentless 19 to 25 mph cross-onshore from the N and NNW. It’s a classic case of "all noise, no signal." The waves will be lumpy, choppy, and messy. If you’re a kite surfer, this setup might look interesting, but for a paddle surfer, it’s a hard pass. The 6 ft to 7 ft days are too big for beginners under these conditions.

The very end of the run, on the morning of Sunday the 26th, shows a little potential. The wind finally drops to a light 3 mph onshore from the NW, and the swell is still a chunky 5 ft from the NNW, with strong energy (393). The period is a short 8 seconds, so it’s windswell, not a groundswell. The forecast says "marginal" due to questionable tides, but with glassy conditions, it might be the closest thing to a salvageable session in the whole 16 days. Still, it’s a long shot.

So, the bottom line: there’s no standout. The best of a bad bunch is that Sunday the 26th morning, but even that’s a gamble. For Coxos, this is a frustrating blank run. Don’t force it. The forecasts can change, but for now, save your energy.

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.
