The Lowdown
Righto, mate. Rusty here, and I’ve been staring at the charts for Watermans for the next 16 days. Let’s get straight into it. The water’s sitting at a nippy 64°F, about 3°F colder than what you’d expect for this time of year – so grab the extra rubber if you’re heading out.
The overall pattern is a bit of a slow burn, then a few spikes that’ll get the heart racing. There’s a gap at the start of the period with no real standout recommendations, so don’t rush to wax up just yet.
Sunday 2nd gets things rolling with a solid 7ft swell from the WSW, period sitting at 14 seconds. The wind is a clean cross-off from the ENE at 16 mph in the morning, so the surface will be clean. The wave energy is pumping (1662). It’s a good start for experienced crew, but the crowds are a factor here – it’s often packed, so get in early.
Monday 3rd sees the swell drop off to 5ft, but the wind goes cross and messy. The energy drops right off (769). Not really worth the paddle. Tuesday 4th is a bit of a tease. The swell jumps back to 7ft with a 19-second period from the WSW – that’s a proper, long-period groundswell (2820 energy). But the wind is cross-onshore, so expect some crumbly, bumpy conditions. Still, that long period means the waves will have good shape and a lot of punch. Wednesday 5th is much the same, with 8ft swell and cross-onshore wind, but the sets will feel powerful (3152 energy). Not the cleanest, but there’s grunt there.
Now, the first real standout moment: Saturday 8th. Holy moly. Early morning we’ve got a 13ft swell from the WSW, period a steady 16 seconds, and the wind is clean cross-off from the SSE at 16 mph. The energy reading is massive (8255). This is big, powerful, long-period swell. For Watermans, a reef break, this is going to be lined-up and perfect for experienced surfers. The afternoon looks even bigger, with the energy going through the roof (16319), but at 13ft with clean winds, it’s likely going to be a bit too much for most. For the crew who charge, this is your window. Be aware that with that kind of period, it might break a bit straight if you’re not on a good peak, but on a reef like this, it should hold up nicely.
Sunday 9th is still solid, with 10ft swell and light NE cross-off winds in the morning – clean again, but still a big boy’s wave. After that, the swell fluctuates but stays punchy through the week. Monday 11th has some cleaner conditions with 8ft SW swell and light S cross-off winds, offering another good, cleaner window for experienced punters.
Thursday 14th is a bit of a sleeper. The swell is a 6ft from the WSW, period 16 seconds, and the wind goes glass in the morning. That is the full-on, flat-calm, tiny-ripple perfection. The energy is moderate (1483), so it’s not a day to be charging, but the quality will be beautiful. For those wanting a fun, clean session without the insane size, that’s your pick.
Saturday 15th also looks tidy, with 7ft SW swell and clean cross-off winds in the morning. The second week overall is more manageable, with swells between 6ft and 7ft, but the windows of good wind are narrower.
Keep an eye on Monday 17th. There’s 7ft WSW swell with light cross winds, but the onshore slop may spoil it. Overall, the standout is undoubtedly Saturday 8th for the sheer size and power, and Thursday 14th for the glassy perfection in a smaller wave.
Rusty.

Information about the Watermans Surf forecast
The above surf forecast table for Watermans provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Watermans can be found by selecting the local surf guide option on the grey menu. Our Watermans 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 (Watermans) 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 Watermans 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.
