The Lowdown
Alright, let’s talk in feet and miles. Same story – Coxos is in a drought for a long time. There’s a big block of nothing from the start all the way through the first week of August. Almost a week and a half of pretty poor conditions. Swell is tiny, wind is trash.
From the afternoon of July 29th through that whole week, it’s a write-off. Swell heights are 1 to 3 feet, with combined energy readings under 100 most of the time. The wind is a moderate to fresh breeze from the north or northwest, choppin’ everything up. The only little glimmer is Thursday, August 6th morning – glassy conditions at Coxos, with a light wind. But the swell is only 2 feet from the WNW with a 10-second period, and the energy is weak at 92. You could get a wave, but it’s not gonna be one to remember.
Then it picks up a little. Saturday, August 8th morning, we see a pulse of 5-foot swell from the WNW with a 10-second period and a combined energy reading of 503 – that’s the strongest we get. The wind is a light cross-shore from the WSW, which is the best wind we get on any day with real size. It’s marginal, but it’s the highlight. By August 10th and 11th, the swell gets to 5-6 feet from the NNW, but the wind cranks up to a strong breeze of 25-28 mph, making it a lumpy, messy situation. That size with that wind at a reef like Coxos is experts-only and still ugly.
The standout is that Saturday, August 8th morning. 5-foot swell from the WNW (close enough to the optimum NNW), 10-second period, strong energy at 503, and a light cross-shore wind. It’s the best we’re gonna get. Water temp is about 68°F, which is average for this time of year.
Coxos is a reef, advanced, fairly consistent. Crowds are often there, so you won’t be alone.
For most of this forecast, with all the wind, it looks better for kite surfing than paddle surfing.

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.
