The Lowdown

Righto, let’s have a look at the 16-day window for Chinamans. Most of the period is pretty average, with a real patch of dodgy weather and swell through the first week that leaves very little to get excited about. There’s a massive gap from the start right through the first few days with zero to poor conditions, so don’t bother paddling out until the following week, really.

Things start to look up from Thursday 20th August. That morning and afternoon we’ll see a solid 5 ft groundswell from the SW with a long period of 16 seconds – that’s proper energy heading in, and the combined swell energy (1709 and 1928) is strong, so there’s plenty of push. Wind stays light to gentle from the west, clean as can be. That’s a standout. It’s clean and has that deep reef power, but it’s still not huge, so the advanced crew will lap it up.

The real gem though, and I’m calling this the pick of the whole run, happens on Tuesday 25th August – the afternoon session. Glassy conditions, ENE breeze at just 3 mph, and a solid 7 ft SW groundswell with a period of 15 seconds (combined energy 1941). Clean faces, good shape, and with the wind glassy and offshore enough, Chinamans will show its best side. Just know it can get crowded, especially when it cleans up.

Later on, Friday 28th August afternoon also has a clean 5 ft SW swell with a 16-second period, light wind, and decent energy (1265) – another good window for experienced surfers. By the 30th, it’s still clean but smaller, and the long period (19 seconds) will make it a bit tricky at this reef, but still worthwhile for those who know the break.

Water temp at the start is 59°, about normal for this time of year, no big anomaly.

Overall: The first week is a write-off. The standout windows are Thursday 20th August, Tuesday 25th August afternoon, and Friday 28th August afternoon – with the 25th taking the prize. Keep an eye on the long-range stuff a week or more out; it’s promising but less certain.

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.
