The Lowdown

Alright, Rusty here. Let’s take a look at what’s on offer for Coxos.

Honestly, the next couple of weeks are looking pretty grim for a proper paddle. The opening days are a write-off with poor conditions and messy cross-shore winds. There’s a pulse of swell arriving around the 28th of August, but even then the wind is a problem. The best chance of anything decent looks like it might be the afternoon of the 28th, but it’s a long way off and the wind is not in our favour.

The first real possibility of a surf appears on Saturday afternoon, 22 August. Coxos is a fairly consistent advanced reef break, and it’s exposed to a NNW swell. The swell is 4 ft from the NNW with a period of 9 seconds, giving a combined wave energy of 287 (moderate). The water temperature is 68°, which is about normal for this time of year. But the wind is blowing SW at 12 mph, cross-shore, creating a chop. The surf is poor. Not a session to bother with.

Sunday, 23 August sees a bigger swell, 6 ft from the WNW in the morning and 6 ft from the W in the afternoon. The period is 11 seconds, so there’s some energy (767 and 596 combined energy) and the wind is cross-offshore, which is clean. But the forecast says “poor surf conditions.” It’s a tough one – the numbers look better, but the call is that it’s not working.

Monday, 24 August gets a 8 ft swell from the WSW with a short 8-second period. That’s over 5 ft, so it’s not for beginners, and the combined energy is 914 (moderate to strong). But the wind is cross-shore and the surf is poor. The setup is messy.

Tuesday, 25 August morning: the swell drops to 5 ft from the W, period 7 seconds, energy 193 (weak). The wind is light and cross-onshore. It’s marginal at best. Not worth getting excited.

The week drags on with similar stories – small, short-period swell, and cross-onshore winds. The afternoon of Friday, 28 August is the only real standout in the whole outlook. The swell is 8 ft from the NW with a period of 11 seconds, pumping a combined energy of 1596 (very strong). The wind is NNW at 12 mph, but it’s cross-onshore. The score is a 2 out of 10, which is the highest of the entire 16-day window. It’s the best on offer, but at 8 ft and with onshore wind, this is for experts only, and even then, it’s going to be lumpy. It’s a long way off, so keep an eye on it.

From Saturday, 29 August onwards, the swell stays small to medium, but the wind is almost always cross-onshore and fresh. The energy numbers drop back down. The surf is consistently poor. From the 30th of August through to the 6th of September, the swell height is below 5 ft, with periods mostly under 8 seconds, and the wind is either onshore or cross-onshore. The combined energy is weak to moderate. There’s a small pulse of longer period (11 seconds) swell on the 6th of September, but it’s only 2 ft to 3 ft with onshore wind.

There’s a gap of several days in the first week where there’s nothing to recommend. The best chance is the afternoon of the 28th of August, but it’s a long-range call and the wind is not ideal. For the rest of the time, it’s a frustrating run of poor conditions. For a spot that’s fairly consistent, it’s a dry spell.

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.
