The Lowdown
Alright folks, Rusty here. Let's get into it for our local stretch.
Right off the bat, I gotta be straight with you – it’s a tough start. For the next week and a half, from Friday the 17th of July right through to the morning of Monday the 27th of July, it’s a write-off. The onshore winds are just relentless, mostly from the NNW, and with swell energy all over the shop – nothing above a 4ft, and the wind's always on it. We're seeing combined energy values as low as 17 (weak) and only creeping up, but it's all poor quality. The first real hope is a glimmer on the morning of Tuesday the 28th of July.
Now, there are a couple of sessions that look like they could be absolute magic, but you’ll need your big-boy pants.
The standout here is Coxos, and it’s all about waiting for the right moment. This reef break is a consistent spot and it's exposed to that NNW swell. The first real window, and I mean a truly special one, is the morning of Wednesday the 29th of July. We’ve got a solid 10ft swell from the NNW, but look at the wind – glassy, with a light SSW breeze, actually cross-offshore. The combined energy is a massive 1380 (very strong wave energy), so there's plenty of grunt. That's a big, powerful wave. At that size, it's strictly for the experienced crew. The water is about average for this time of year.
The Thursday the 30th of July morning session is the other one to circle on the calendar. It's the same story: 10ft NNW groundswell with a 9-second period, and it's dead glassy with a light SSW breeze. Energy is still at a whopping 1178. It doesn't get much cleaner for a big-swell reef break. This is proper, demanding surf. Expect crowds to be likely here, as it doesn't take much for the word to get out.
So, to boil it down: you’re looking at a long wait until the 29th of July, but when that window opens, it’s world-class. Don't waste your time on that first week. Save your energy for those big, glassy mid-week mornings.
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.
