The Lowdown
Right, grab a coffee mate, let’s have a look at what’s cookin’ for Coxos.
Honestly, the next week or so is a bit of a write-off. We’re looking at a long stretch of pretty ordinary conditions, with a lot of onshore wind and messy, lumpy waves. The first real surfable day that shows any promise is a long way off, so we’ve got to be patient. There’s a big gap of nothing but poor surf until the 28th of July.
The one standout that’s actually worth circling on the calendar is Tuesday morning, the 28th of July. This is the real deal. Swell is up to 7 ft from the NNW, and the wind is swinging around to a light offshore from the SSW at only 3 mph. That’s a recipe for clean, lined-up waves at this reef. The combined energy of all swells directed here is strong, at 694, so there’s plenty of push. The period is a solid 10 seconds, which is proper groundswell, giving you good shape and power. For a spot like Coxos, which is a fairly consistent reef break, this is about as good as it gets. The water is about average for the time of year, so no crazy thermals to worry about. Just keep in mind, it’s an advanced wave and crowds are often here, so you’ll be sharing the peak.
Before that, the 25th and 26th see a spike in size—6 ft to 7 ft—but it’s blown out by 19-22 mph cross-onshore winds. That’s poor quality, lumpy, and honestly, it’s more interesting for a kite surfer than a paddle surfer. The 27th is a bit of a tease; the afternoon has a 5 ft swell with moderate energy (515) and onshore wind, but it’s just marginal.
After that 28th morning window, things drop off again. The 29th has some 4 ft swell but the wind turns cross and cross-on, making it choppy. The 30th is glassy in the morning with 3 ft from the NNW, but it’s small and only a light breeze. The 1st of August and beyond are just a mix of tiny, short-period, wind-affected leftovers. There’s a small pulse on the 4th of August with 5 ft but again, cross-on wind and short period makes it a no-go.
So, the play is clear: wait for the 28th morning. That’s your window. Everything else is a gamble on a blown-out day.

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.
