The Lowdown
Alright, Rusty here, giving you the lowdown on Chinamans for the next couple of weeks.
This is a classic exposed reef break, and it's got some serious potential. The water is about 59°, which is normal for this time of year, so nothing to worry about.
We kick things off on Thursday, August 13th, with a big, powerful SW groundswell. The combined energy is massive – over 4000 – with waves around 10 feet. The wind is messy on the morning, but it cleans up by the afternoon as it turns cross-offshore. Still, 10-foot surf on a reef is for experts only.
The real standout is Friday morning, August 14th. The swell is still a solid 10 feet from the SW, with a 16-second period, meaning it's a proper long-period groundswell. The combined energy is nearly 4000. But the wind is the key here – a light, 6 mph cross-offshore breeze. That's going to glass the wave faces up. It's described as excellent for experienced surfers, and that's the truth. It's going to be clean, powerful, and reeling down the reef. The paddle out will be a mission, but the longer gaps between sets will help. This is the best session of the whole forecast.
The wind goes onshore from the ESE from Friday afternoon through the weekend. The swell drops a bit to 6-7 feet, but the combined energy is still high (over 2000). The chop and onshore wind will make it a bumpy mess. Saturday and Sunday are not worth paddling out for.
Monday, August 17th, sees lighter winds, but the swell has dropped to around 5 feet. It's marginal. Then Tuesday, August 18th, the wind goes offshore from the north, but the swell is down to 4-5 feet. The energy is moderate (around 850-1477), but the clean conditions mean it'll be a fun, smaller wave.
The next proper highlight is a week away, on Thursday morning, August 20th. The swell bumps back up to 7 feet from the SW, with a 16-second period and a combined energy of 1880. A moderate offshore wind from the north will keep it clean. This is solid, powerful surf for experienced surfers again.
After that, we get a big spike in swell around August 23rd and 24th – 10 feet plus – but it's accompanied by very strong winds, making it a chaotic mess. Then we have a massive pulse on August 26th, with waves hitting 13 feet and a combined energy of over 13,000. That's a ridiculous amount of energy, but the wind is a strong onshore, so it's going to be lumpy, choppy, and dangerous. That's a day for the tow-in crew or the very brave. The surf finally cleans up in the last few days of the month, but it's back to smaller, cleaner waves around 3 feet.
So, to sum it up: Friday morning, August 14th is the absolute winner – big, clean, powerful groundswell with light offshore winds. Thursday morning, August 20th is the next best bet, a solid, clean, powerful session.
Rusty out.

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.
