The Lowdown

Alright, let's talk in old-school units. We've got Chinamans reef, and it's about to get real with a solid SW groundswell. The water's sitting right around 59°F, which is dead average for this time of year. The key is the length of this run – there's surf coming, but you'll need to be patient.

First up is Thursday the 13th of August. We're looking at a 10-foot SW groundswell with a 15-second period. That's proper long-period energy, with the combined swell energy at 3557 (moderate-strong). A cross-off wind from the W at 12 mph will keep things clean. This one's for the advanced crew only – 10-foot is getting into expert territory, and a reef break with that much juice needs respect.

Friday the 14th morning is the first big standout. The swell is still 10-foot from the SW, and the period stretches out to a very long 16 seconds, with energy up at 3937. The wind drops to a light W breeze at 6 mph, cross-off. That's about as clean as it gets. Excellent for experienced surfers – the long period gives you long, powerful lines, but be ready for the sets on that reef.

We get a clean breather on Thursday the 20th of August morning. The swell drops to a more manageable 7 feet, still SW at 16 seconds. The wind is a light NW offshore at 6 mph. That's going to be glassy, clean, and a much nicer size for strong intermediates. Energy is 1978 (moderate).

Then the big stuff returns. Saturday the 22nd of August morning shows a 13-foot SW swell, but with a cross-on SSW wind at 16 mph. That's a choppy, blown-out mess. The combined energy is 5995 (strong-very strong), but with that wind, it's a no-go. The afternoon cleans up a touch but still isn't great.

Here's the real second-week standout. Sunday the 23rd of August morning brings a 10-foot SW groundswell with a 15-second period (energy 3539) and a light NW offshore wind at 6 mph. Excellent conditions for experienced surfers with a glassy surface and big, clean swell. That's the pick of the trip if you're after size.

And then, there's the wild card. Friday the 28th of August morning is looking truly exceptional. The swell is 8 feet from the SW, but the period is a monstrous 19 seconds – very, very long-period groundswell. The combined swell energy is a massive 6065 (strong-very strong). And the wind? Glassy. SW at 3 mph. That's a rare combo of massive, powerful energy and a flat surface. Only for experts at that size on a reef, but if you're one, that is the session to circle.

Crowds at Chinamans can pop up *sometimes*, but with that quality and the advanced nature of the spot, it shouldn't be a zoo. The long-period stuff is best here at the reef, where the lines will stand up and wall up nicely.

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.
