The Lowdown
Alright, this is Rusty. Let's have a look at what's on the cards for Coxos.
We're looking at a pretty grim start here, I'm not gonna lie. The first week and a half is a write-off. From the 18th right through until the 29th of July, it's all junk. We’re talking weak, short-period windswell, blown out by onshore or cross-onshore winds that just won't let up. The combined energy is weak, often under 100. It's a total grind. You’d be better off waxing your board at home than looking at this lineup.
Now, the light at the end of the tunnel comes on the morning of Thursday, 30th of July. This is the real deal. A solid NNW groundswell pushes in at 8.2ft, a long 9-second period, and for the first time we get a clean, cross-offshore breeze from the ENE. The energy jumps to over 1000 (1020) – that's proper power. The comment says "excellent surf conditions for experienced surfers," and at 8.2ft, it's big, so this is expert territory, but if you can handle it, this is the session to circle. The water temp is about 68.2°F, which is bang on average for this time of year, so no surprises there.
Following that, the Friday morning of the 31st of July is another standout. The swell drops a touch to 6.9ft, but it's still a solid chest-to-head high, with the same clean ENE cross-offshore wind. The energy is strong at 716, and it's noted as "very good surf conditions." This is a much more manageable day for the strong intermediate crowd.
The real monster of the forecast is the start of August. The Saturday, 1st of August morning brings a 9.8ft swell from the NNW with very strong energy (1350), and again, clean offshore winds from the ENE. That is a proper big-wave day, experts only. The Sunday, 2nd of August morning pushes it even bigger, with an 11.5ft swell and a whopping 2296 combined energy. The wind is cross-offshore from the east, so it’s clean, but at that size, you’re talking about a very serious, heavy wave. It’s a long-range call, so it’s promising but less certain, but if it comes together, it’ll be a day to remember.
Take it easy, and score one of those clean ones for me.

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.
