The Lowdown
Alright folks, Rusty here. Let’s talk about what’s in store for the next couple of weeks. For the first ten days or so, it’s going to be a tough stretch. The wind is nearly always on it or cross-on it, and the wave quality is described as poor. We’ve got a long gap of flat, messy conditions to sit through. But hang tight, because there’s a glimmer of hope right at the very end of the window.
The best session on offer, and the only real standout, lands on Tuesday, August 11th in the morning. That’s over a week and a half away, so keep your expectations in check, but it’s worth marking on the calendar. The swell is a solid 6 ft from the NNW, with a period of 7 seconds. The combined energy of all swells will be moderate (368). The big news here is the wind: a light offshore breeze from the SE. That’s going to clean up the face at Coxos (reef) nicely. It’s a spot that’s fairly consistent and exposed to the swell, so it should handle this size. The water temperature is about 69°F, which is pretty normal for this time of year. Just a heads up, this is an advanced wave, and with that size, definitely not for beginners.
Before that, there’s a couple of days that are worth a look if you’re desperate: Friday, August 7th and Saturday, August 8th have some size, with swell around 6 ft to 7 ft, and the combined energy jumps up to strong (544). But the conditions are marginal, with cross-onshore winds and questionable tide windows. The swell is short period, around 7-8 seconds. It’s going to be a bit of a mess and more suited to experts. For a while there, it looks more interesting for kite surfing than paddle surfing.
Outside of that morning on August 11th, don’t expect much else. The rest of the days are plagued by poor surf conditions and onshore or cross-onshore breezes. It’s a quiet run, but that one clean window is worth chasing.
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.
