The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin’ for Coxos over the next sixteen days.

Right off the bat, I gotta be honest with you – this is a tough period. The whole sixteen-day window is a real struggle. There’s no good surf on offer at all. Every single session is rated as poor surf conditions, and the scores are all zero. We’re lookin’ at a solid blank run from the start of the forecast on July 31st all the way through to August 15th. That’s a long stretch with no real recommendations.

The whole pattern is dominated by cross-on winds. For the most part, we’ve got moderate to fresh breezes out of the north and north-northwest, creating choppy and lumpy conditions. The swell is almost always comin’ from the west-northwest to north-northwest, which is basically the opposite of the optimum swell direction of north-northwest for this break. The periods are mostly short, between 6 and 9 seconds, so it’s windswell, not groundswell. The combined swell energy is weak for the first few days, with values around 42 to 66. It picks up a bit into the first week, hittin’ moderate levels like 166 and 187, but it’s still all cross-on and messy. By the second week, the energy gets stronger – on August 13th morning we see 363 (moderate energy) – but the wind is still a fresh 19 mph cross-on. The biggest swell shows up around August 10th and 13th, with heights hittin’ 6 ft, but with those winds, it’s only for experts who don’t mind a battle. For beginners, anything over 5 ft is too much, and with the chop, it’s not a fun paddle.

Water temperature at Coxos is 68°F, which is just 0.2°F below average for this time of year – so, normal. No surprises there.

Given the persistent cross-onshore winds, poor surf quality, and the beach-and-reef setup, this stretch looks more interesting for kite surfing than paddle surfing. Honestly, if you’ve got a kite, you might find some fun. For a surfer? It’s a waiting game.

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.
