The Lowdown
Rusty here, looking at our local stretch.
For the next ten days or so, we’re in a bit of a rut. A stubborn northerly wind is messing up the surface, leaving everything choppy and cross-onshore. From Thursday the 10th all the way to the 22nd, it’s a long, grim stretch of poor-quality waves. Not much to get excited about.
The first real glimmer of hope comes on Wednesday the 23rd. The morning is looking glassy with a light breeze, and while the swell is small at 3ft, the clean conditions will be a welcome change.
Thursday the 24th is a big step up. A clean 7ft swell from the NNW meets a light cross-offshore wind. That’s a proper day, and the kind that gets the stoke back.
The absolute standout is Friday the 25th. That morning, we’ve got a 10ft swell from the NNW with a 15-second period – a serious groundswell with huge energy. The wind is light and cross-offshore, so it’ll be clean and powerful. That’s for experts only at that size, especially on a reef. The afternoon swell gets even bigger to 12ft, but the wind switches onshore. Keep your eyes on this one, it could be the session of the outlook.
Good luck 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.
