### The Full Run Down
Starting out, through Sunday afternoon, July 12th, the water at Coxos is sitting at 18°C. That’s about a degree colder than usual for this time of year, so a bit of a nip in the air. But there’s no point getting in. The swell is a tiny 0.7m from the NW, period of 9 seconds, but with a 20 km/h WSW cross-wind, it's just messy.
The entire week from Monday, July 13th right through to Saturday, July 26th is pretty much a write-off. We get a few mornings with light offshore breezes (like the 14th and 15th), but the swell is tiny – under 0.8m – and the period is short and weak (combined energy under 100). The rest of the time, it’s cross-onshore winds with chop.
The situation actually gets a little more interesting around Saturday, July 18th and Sunday, July 19th. The swell pushes up to 1.7m to 2.4m from the NNW, with combined energy climbing into the moderate range (281 to 640). But the wind is a fresh 25-30 km/h cross-onshore, so it’s lumpy, choppy, and not worth paddling out for. For kite surfing, with that much wind and swell, it might be a different story. For a paddle surfer, stay on the sand.
The best chance, if you can call it that, comes on Monday, July 20th and Tuesday, July 21st. A solid groundswell arrives: 3.0m on Monday morning, dropping to 2.5m Tuesday morning, both from the NNW with good period of 9-10 seconds. That’s a serious amount of energy (1469 to 1502 on Monday!). However, it’s blown out by onshore winds, and for a wave that size–over 2.5m–this is serious, expert-only territory. The surf will be big, powerful, and ugly.
After that spike, it quickly fades. By Wednesday, July 22nd, we’re back to 1.9m dropping to 1.0m by Thursday, and the wind is still on it. The final days of the forecast (July 24th to the 27th) are just more of the same: weak, onshore slop.
Honestly, for Coxos in this 16-day window, there’s no standout session. The pulse on the 20th and 21st has the size and energy, but the forecast quality is shot by the wind. I’d call it a blank run for clean waves. Keep an eye on things, because in an exposed spot like this, the forecasts can change. But as it stands? Leave the board in the car.

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.
