The Lowdown
Alright, grab your boards and listen up. It’s Rusty here, and I’ve been staring at the charts for our stretch of coast. We’ve got a wild ride ahead over the next couple of weeks, with a proper lull at the start before things get seriously interesting.
The opening days are a write-off for a decent paddle. We're looking at a couple of days of poor, choppy conditions with onshore junk and moderate to fresh breezes. The swell is there, but it’s messy. You’d be fighting a losing battle. This is the calm before the storm, coast-wise.
Things start to clean up around Friday the 11th, but it’s still marginal, with a lot of cross-shore energy making things tricky. The waves are dropping a touch, but the wind is slowly coming around. The real shift happens on Sunday the 13th. The wind finally swings offshore, and the ocean glassies right up. That morning, it’s a bit small at 4ft with a fresh offshore, but by the afternoon, the wind eases and it's clean. This is where we start to see some real shape.
Now, keep your eye on Chinamans for one of the genuine standouts of the whole period. The morning of Monday, September 21st is the one. We've got a solid 5ft of SW groundswell rolling in with that long 16-second period, and the wind is a clean, moderate offshore. Conditions are set to be excellent. It’s a reef break and pretty advanced, so only the crew will be out there. That’s the pick of the bunch for me.
Before that, the Saturday morning of the 19th is also going to be pumping. That’s a big one, with 12ft of SW swell and a huge 9472 combined energy reading. It’s going to be powerful and probably only for the expert crew out there on the bigger boards. Wind is cross-off, so there should be some clean faces, but that size is no joke. A few days prior, the morning of Thursday the 17th is also looking good with cleaner conditions and smaller, more manageable waves—a solid option if the big Saturday swell is too much.
There’s a brief window of smaller but clean surf around Monday the 21st as well, with offshore winds and clean lines, before we see another pulse of energy. The water temp is running about average for this time of year, which around here means a good summer wetsuit is the go.
So, there's some patience required to start, but the second week has some real firepower. The long-period swells like this are best on the reefs, which is where Chinamans will shine.
Rusty.

Information about the Chinamans Surf forecast
The above surf forecast table for Chinamans provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Chinamans can be found by selecting the local surf guide option on the grey menu. Our Chinamans 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 (Chinamans) 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 Chinamans 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.
