The Lowdown
Alright, Rusty here, let’s talk about what’s brewing at Watermans.
We’ve got a slow start, but once the stars align, there’s some serious potential. The water’s sitting at 64°, which is a bit colder than normal for this time of year, so you’ll want a good 4/3 or maybe booties if you’re sensitive.
The first few days, Monday the 10th through Wednesday the 12th, are pretty much a write-off. It’s messy, with strong cross-onshore winds and a lumpy, poor-quality swell. The energy is moderate, but the conditions are just ugly. Not worth paddling out.
Thursday the 13th is where things start to turn. The morning session is the pick of the early period. We’ve got a clean 7ft swell from the WSW, with a long 16-second period, and a light cross-offshore breeze from the ENE. That’s the kind of setup that grooms the reef nicely. The combined wave energy is solid (2119), and the conditions are clean. This is for experienced surfers only, as it’s a powerful groundswell and the reef can be unforgiving. If you’re an intermediate, wait for a smaller day.
Friday the 14th morning is a repeat of the same magic – clean 7ft WSW swell, 16-second period, and a light offshore from the NE. Another top-notch session for those who know what they’re doing.
Saturday the 15th afternoon is a real standout. The wind goes glassy, and we’ve got a clean 6ft WSW swell. That’s the kind of afternoon you dream about – smooth, empty lines, and the reef firing. The energy is still moderate (1442), but the quality is sky-high.
Sunday the 16th offers a solid afternoon session: 8ft WSW, 15-second period, and a clean cross-offshore breeze. The long period means the reef will line up perfectly, but it’s best for experienced surfers as the swell has some serious push.
Monday the 17th gets blown out again with strong cross-onshore winds and messy, poor-quality surf. Skip it.
Now, for the real standout of the entire outlook: Tuesday the 18th morning. This is the one. A massive 12ft WSW groundswell with a 15-second period, combined with a clean offshore breeze from the ENE. The wave energy is pumping at 5176. This is exceptional, expert-level surf. The reef will be handling a lot of moving water, so only the most experienced should even think about it. This is a big, heavy, world-class session.
The following week has some promising windows. Sunday the 22nd morning is another absolute gem: 12ft WSW, super-long 18-second period, and a clean cross-offshore breeze. The wave energy is through the roof at 7221. This is arguably the best session on offer, but it’s a long-range call, so keep an eye on it. Perfect for experts only.
The 23rd and 24th have some clean windows, but the wind mixes up, and the energy drops. Overall, the best bets are the 13th, 14th, 15th afternoon, 16th afternoon, 18th morning, and the standout 22nd morning.
Stay safe out there, and don’t be a hero if it’s over your head. This is Rusty, signing off.

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.
