The Lowdown
G’day, Rusty here. Chinamans is your only play in this outlook, and it’s quite a ride over the next 16 days.
Right now, though, there’s nothing doing. The first decent surf won’t show until the morning of Thursday the 30th of July. So we’ve got a two-day gap of flat or messy junk before anything worthwhile.
That Thursday morning brings the first real hope. Swell drops to 6ft from the SW, period a solid 13 seconds – a proper groundswell pushing moderate wave energy (991). The wind is glassy, dead calm. That combo is a gem: clean faces, long lines rolling into this reef. It’s still advanced territory at that size, so not a beginner’s wave. The water sits at 59°, which is dead normal for this time of year. Friday the 31st of July stays good. Morning sees 4ft SW swell with a light cross-off breeze, clean as a whistle. Afternoon gets an offshore from the north, same size, period bumping to 14 seconds. Beautiful, but the swell is modest – you’ll be hunting for the sets.
Now, here’s the standout: the morning of Friday the 7th of August. Swell pushes to 8ft out of the SW, period 16 seconds – that’s a long-period groundswell with strong energy (3715). Wind is gentle offshore from the NNW, making for clean, lined-up waves. This is a reef break, so that long-period swell will wrap in beautifully. It’s expert territory at that size; the power is serious. The guidance shows this as the pick of the whole window – excellent conditions for experienced surfers. Keep in mind, this spot can get crowded sometimes, and this kind of swell will bring the crew.
August 12th is a wild card. The Wednesday morning swell is a massive 12ft from the SW with a very long 19-second period, churning up extreme wave energy (17770). That’s way too big for a beginner, and the report says it may be too big for this break. Light cross-onshore wind keeps it from being messy, but only expert chargers need apply. The afternoon is similar, still huge.
There are a lot of messy days in between – Sunday the 2nd of August gets onshore winds and poor conditions, and the second week has a few clean but marginal windows. For the bulk of that second week, expect inconsistent, smaller surf with moderate breezes. Take the Thursday the 4th of August afternoon as a decent but not standout option: 4ft clean cross-off, solid 16-second period – a fun, cruisy session for the experienced.
Rusty signing off.

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.
