Right, let’s talk waves. I’m looking at a long stretch for Coxos, and the first good moment is a few days away. No sense getting worked up until then.

The first surfable waves roll in on the morning of Sunday, July 12. Swell is 2ft from the northwest, period around 9 seconds, and winds are light cross-offshore from the south. The water temp is about average for this time of year – nothing unusual.

Coxos is a reef break, exposed to northwest swell, which is exactly what it needs to work. It’s fairly consistent and gets crowded often. The wave energy is moderate (154), so there’s some push. It’s clean, glassy, and worth the early paddle. It’s not the biggest swell of the whole forecast, but it’s the only session where the wind actually helps.

Monday 13 July morning picks up where Sunday left off – 2ft from the west, 8-second period, light cross-offshore winds from the south-southwest. Again, clean and surfable, moderate energy (102). Not epic, but solid.

From Tuesday 14 July all the way to Monday 27 July, it’s a rough ride. The wind goes cross-onshore or straight onshore and never lets up. Swell tries to build – by Saturday 18 July it hits 5ft from the northwest with moderate energy (211) – but the wind is cross-onshore, making it choppy and lumpy. Periods stay short, 6-7 seconds, so the waves don’t have the power to hold shape against the wind.

Through the week of 20-25 July, the swell stays in the 4-5ft range from the northwest, but it’s onshore or cross-onshore every day. The wave state is poor. For advanced surfers, there will be some heavy, messy walls, but it’s a slog. For beginners, once the swell tops 5ft on the 18th and 20th, it’s too big and too rough. At that point, with the wind and the chop, this setup looks more like a kiteboarding zone than a paddle.

By the final days – July 26 and 27 – the swell drops to 1-3ft from the west-northwest, but the wind is still onshore or cross-onshore. No clean window.

Best call? Sunday morning July 12. That’s your one standout: clean, light winds, and a working swell. After that, it’s a two-week stretch of poor conditions. The bigger swell later in the month is on the charts, but the wind is the enemy. Keep an eye on it – forecasts can change – but right now, it’s a tough run for Coxos.

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.
