The Lowdown

Alright, grab a coffee and settle in, because I’ve got the full picture for Coxos over the next couple of weeks. To be straight with you from the start, it’s a tough outlook. This is one of those runs where the ocean just isn’t playing ball for us.

The overall pattern is a long, frustrating stretch of poor surf. We’re looking at a solid gap with no real recommendations right through the first week and into the second. The first hint of anything remotely interesting doesn’t show up until Monday, July 21st, and even then, it’s only a marginal call. So, for the first six days from Wednesday the 15th through to Sunday the 20th, it’s basically a write-off. The conditions are consistently poor, with onshore or cross-onshore winds and small, weak swell. Don’t bother paddling out.

Coxos is a reef break, and it needs the right combo. The optimum swell direction is from the NNW. Through the early part of the forecast, we’re seeing a lot of windswell from the WNW and NW, with a short period, and the combined wave energy is weak as anything – values hanging around the 20s and 40s. For example, on Wednesday morning the 15th, it’s a clear sky with a light cross-onshore, but the swell is just 1 ft from the WNW at 9 seconds, with a combined energy of only 47. It’s just not happening.

The first day that deserves a mention is Monday, July 21st. The morning session shows a bit of a pulse. The swell is 4 ft from the NNW, which is the right direction, with a period of 9 seconds and a combined energy of 215 – that’s moderate energy, finally. The wind is a light cross-onshore from the WSW, which is okay, but not ideal. The report calls it “marginal” due to questionable tide conditions, but it’s the best we’ve seen all week. The afternoon cleans up a bit with a pure cross-shore wind, though the swell drops a little. It’s not a standout, but it’s the only window of possibility.

After that, it goes flat again. The energy drops back into the weak zone, and the winds stay messy. The longer-range looks a bit more interesting, but it’s a mixed bag. By Saturday, July 26th, the swell size builds to 7 ft from the NNW, but the period is a short 8 seconds, and the wind is a moderate cross-onshore. That size is going to be a handful on a reef, and with the wind being cross-onshore, it’s going to be choppy and lumpy. The energy is high (549), but the quality just isn’t there. This is more of a kite-surfing setup than a clean paddle session.

The water temperature is about average for the time of year, no wild anomalies to report.

So, the honest truth? There’s no true standout session in this 16-day window. If you’re desperate, keep an eye on the morning of Monday, July 21st, and maybe the afternoon of Saturday, July 25th, but keep your expectations low. The rest is a long, quiet spell. Don’t sell your board, but maybe give it a rest for a bit.

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.
