The Lowdown
Alright, grab your spring suit, here’s the read for the next couple of weeks.
We’ve got a bit of a mixed bag coming our way, but there’s definitely some good ones to lock in. The opening run is looking clean, with a solid pulse of south-west groundswell and those offshore northerlies doing the business. Water temp is sitting at 60°, which is bang on average for this time of year, so no surprises there.
Kicking off Sunday, July 19th, Chinamans is the place to be. It’s a reef setup, so you’ll want your wits about you, but it’s fairly consistent. Sunday morning sees a 3 ft south-west swell, a 12-second period, and a clean 12 mph offshore breeze. The energy is moderate (398). By the afternoon, the period jumps to 18 seconds and the energy bumps up to 667, making it even better. The wind stays offshore, and the water will be glassy. This is a standout.
Monday, July 20th, keeps the run going. Morning is 4 ft south-west with a 15-second period, offshore wind, and energy at 714. Monday afternoon gets even better: 5 ft, 15 seconds, and the wind drops to 9 mph offshore. The energy hits 1045, which is a solid wall of power. This is excellent for experienced surfers. Tuesday, July 21st, holds similar size and direction, with a light offshore in the morning and a cross-offshore in the afternoon. Still clean, still good.
We hit a rough patch from Wednesday, July 22nd, through to Friday, July 31st. The wind swings onshore or cross-shore, and the swell gets messy or just too big with poor conditions. Wednesday is a write-off with strong wind and rain. Thursday and Friday have swell over 8 ft, but it’s cross-onshore and choppy – that’s for experts only, and even then, it’s not pretty. The energy values are huge (4477 to 5160), but the wind kills it. From July 28th to July 31st, it’s all poor, with strong winds and lumpy seas. This is a long gap of no good surf, about a week of nothing to write home about.
Then, we get a little glimmer. Saturday, August 1st, the wind goes glassy in the morning. Swell is a small 3 ft, but with a 17-second period from the south-west, and energy at 455. It’s a clean, small day for a longboard or a fish. Not a standout, but a nice break from the crap.
Sunday, August 2nd, sees a jump in size: 7 ft in the morning, 10 ft in the afternoon, both from the west-south-west. The wind is cross-onshore, but fairly light. The energy is strong (1483 to 3908). It’s a bit lumpy, but passable for a keen surfer.
Monday, August 3rd, is the end of the forecast. You’ve got a 10 ft south-west swell with a 17-second period, light cross-onshore wind, and huge energy (4777). The period is long, so this will be a proper groundswell. It’s a bit big for the average punter, but for the experienced crew, it’s got potential. The wind is light, so there’s a chance it cleans up. It’s a promising end to the window, but it’s a week and a half away, so keep an eye on it.
Best on offer: Sunday, July 19th afternoon, and Monday, July 20th afternoon at Chinamans. Clean, solid, and offshore.

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.
