The Lowdown

Alright, surfers, Rusty here. Let’s talk about the next couple of weeks for Coxos.

To be straight with you, it’s looking like a pretty grim run. The forecast is full of poor conditions, strong onshore winds, and a whole lot of chop. You’re going to have to be patient, because for the first five days, from Sunday the 23rd through to Thursday the 27th, it’s mostly a write-off. The swell is there, sometimes head-high, but the wind is wrecking it, and there’s no point even suiting up for that mess.

The water temp is about average for the time of year, so nothing weird there.

Now, if you’re desperate, there’s a tiny window on Tuesday morning, August 25th. We get a drop in the wind, with a light cross-off breeze from the SW and some clean conditions. The swell is only around 5 ft from the W with a weak period of 7 seconds, so it’s going to be small and a bit weak (combined energy of 193). It’s surfable, but it’s nothing to write home about. Just a chance to get wet if you’re really jonesing.

The only real standout, and I mean the *only* one, comes on Friday morning, August 28th. This is the best bet on offer. The swell picks up to 7 ft from the NW with a period of 10 seconds, giving it some decent energy (combined energy of 1066). The wind is a gentle cross-onshore breeze from the N, which keeps it fairly clean, though it’ll still have a bit of chop. This is the biggest, most powerful swell of the whole 16-day window. It’s a bit much for beginners, but for the rest of you, this is your session.

After that, we drop back into a long, drawn-out fade. From the 29th of August all the way through to the 7th of September, it’s a bleak run. The swell disappears, the wind stays onshore or cross-onshore, and the conditions are consistently poor. There’s a good 8-day gap with no real recommendations. It’s just flat and choppy. For a spot like Coxos, this kind of blank run is more normal for this time of year.

Stay tuned, forecasts can change, but right now, lock in that Friday morning and don't hold your breath for the rest.

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.
