The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for our little slice of the coast.
Right off the bat, I gotta be straight with you – the next week and a half is a tough one. We’ve got a long stretch of onshore and cross-onshore winds that are just ruining everything. The swell is small, under 3 feet, and the period is short, so the energy is weak. The first real chance of anything decent doesn't show up until the end of the month.
The standout window is from the 28th of July through the 30th. We get a proper pulse of swell from the NNW, pushing up to 10 feet. The combined energy jumps massively, hitting 705 (moderate) on the Tuesday morning and peaking at a very strong 2006 on the Wednesday morning. For a spot like Coxos (reef), this is proper groundswell territory. The period stretches to 10 seconds, which is a solid groundswell, and the wind looks like it might finally ease off, with a shot at some offshore NW flow on the 30th morning. That setup is your best bet for clean, wedgey waves on the reef. But keep in mind, 10 feet is expert territory. If you’re not comfortable on a big, powerful reef wave, give this one a miss.
The main problem is the wind. For the first 9 days, it’s mostly onshore or cross-onshore, moderate to fresh breeze, keeping the surface lumpy and choppy. The water temp is about average for the time of year, so no surprises there.
So, to sum it up: don’t bother paddling out until the 28th. That’s your go. The 29th and 30th look the best, but it’s still a week and a half away, so keep an eye on it. The rest of the window is a write-off, with strong winds and messy, weak surf. It’s a long wait for a few good sessions, but that’s how it goes sometimes.
Stay salty,
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.
