The Lowdown
Alright folks, Rusty here. Let's get into what the next couple of weeks are looking like for our local reef.
Right off the bat, Sunday the 30th is your best bet if you're an experienced surfer. We’ve got a proper 8ft groundswell rolling in from the WSW with a long 18-second period, packing some serious grunt – we're talking strong wave energy here (3237). The water's sitting at 65°, which is pretty much what you'd expect for this time of year. The magic of this one is the wind: a glassy NE at just 3 mph, keeping it clean and lined up. This is a classic, powerful reef setup, not one for the groms or weekend warriors. The crowds are often around for a quality session like this, so get in early.
By Sunday afternoon, that southerly change pushes in, turning the wind onshore and the conditions turn ordinary. Monday and Tuesday are a write-off with onshore winds and messy conditions. The swell sticks around but the wind just wrecks it.
We hit a real rough patch from the 3rd of September onwards. Strong winds, some rain, and lumpy, blown-out surf. By Friday the 4th, we're looking at 13ft of straight-up messy, wind-affected swell. The combined energy is massive (7505), but with 16 mph cross-onshore winds, that’s a kite-surfing proposition, not a paddle one. The whole first week of September is a write-off for clean waves.
Now, looking at the second week, there are a couple of windows trying to open up. The 6th of September has a 13ft swell from the SW with an insane amount of energy (10495), but the crosswind will chop it up.
Here's the standout in that second week: Monday the 7th of September. The swell hangs solid at 10ft from the WSW, with a long 16-second period and very strong energy (4242). The wind is a dream – light offshore from the east at just 3 mph. This will be beautiful, powerful reef waves, but only for the experts. This is one to circle on the calendar, as long-range calls can always shift a bit.
After that, the week looks average again, with cross and onshore winds messing with solid swell. There's a glimmer on the morning of the 10th of September with an 12ft swell from the WSW, an 18-second period, and very strong energy (7451) in lighter cross-shore winds – that could be something. And again on the 14th of September, with a 10ft swell but a shift to a more westerly direction.
So in summary: grab Sunday the 30th if you can. Then wait out two weeks of wind and chop for a promising but not guaranteed session on the 7th of September.
Stay safe, and don't get caught inside.

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.
