The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for Coxos over the next couple of weeks.

Right off the bat, I gotta be straight with you – it's a bit of a rough stretch. The forecast kicks off with a few days of small, weak swell and the wind is mostly putting a chop on it. The combined energy of all swells directed here is only around 130 (moderate wave energy) on Sunday, dropping to 73 (weak wave energy) by Monday morning. The water temperature is sitting at 68°F, which is about average for the time of year.

For the first week, from Sunday the 2nd of August right through to Saturday the 8th, the swell is tiny, mostly under 3 ft, and the wind is consistently cross-onshore or onshore from the north or northwest. The period is short, between 6 and 10 seconds, so it's a messy, weak windswell. Honestly, it looks pretty poor for a paddle. The real story is the swell building from the 6th – you'll see it jump to 5 ft on Thursday, but it's accompanied by a fresh breeze creating lumpy, choppy conditions. That's more of a kite surfer's setup than a clean surf day.

The following week, from the 9th to the 16th, the swell is a bit more consistent – we're looking at 4 ft to 6 ft from the NNW, with a period of 8 to 9 seconds. The combined energy is strong, hitting 408 (strong wave energy) on the 14th. But the catch is that the wind is still mostly cross-onshore or onshore, keeping things chopped up. Most of these days are rated as "marginal" or "poor" for surf, and we're not seeing any clean windows yet.

Now, here's the one that's got a bit of a spark. Looking at Monday the 17th of August, there's a clear window. For the morning session, we have a 5 ft swell from the NNW with a 9-second period, combined energy of 360 (strong wave energy). The real kicker is the wind – it's a light cross-offshore breeze from the SSW, with just a slight air. The notes say "clean," and for a reef break like Coxos that's exposed and likes a NNW swell, that's the best we're going to see. It's a standout, but remember, it's a long-range call, so keep your fingers crossed.

The rest of that week and the weekend are just going to be a grind of onshore slop. The swell is there, but the quality isn't. So, in summary, sit tight, watch the wind, and pencil in the morning of Monday the 17th as your best shot for a clean session.

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.
