The Lowdown

Alright, Rusty here. Let’s get into it.

We’ve got a patchy start with a pretty solid run of mid-period WSW groundswell building, but the early week is messy. The real quality is going to be further out, with a couple of windows that look proper.

First up, Watermans is a reef break and it’s getting a consistent, solid push from the WSW. The water temp is sitting at 65°, which is about normal for the time of year – nothing unusual there.

Saturday the 29th is a write-off: onshore winds and weak energy (819) with only 3ft of swell. Not worth paddling out. Sunday the 30th morning is where things start to lift. We’ve got 8ft of WSW swell with an 18-second period, so that’s a long-period groundswell, and the combined energy is cranking at 3237. The wind is NE at 10 km/h (about 6 mph), cross-offshore, so it’ll be clean. That’s the standout for the first week – really good shape, solid size, and the reef will handle that period well. It’s big enough for experienced surfers, so if you’re not confident, sit this one out.

Monday the 31st and Tuesday the 1st are poor – onshore winds and messy cross-shore chop, with the swell hanging around 7ft but the period dropping. Not recommended.

Thursday the 3rd and Friday the 4th are a write-off again – strong onshores and poor quality. The swell is still there but it’s ugly.

Now, here’s the real gem. Sunday the 6th of September has a morning session that looks magic: 10ft of WSW groundswell at 14 seconds, but the wind is light SSE at 10 km/h (6 mph), giving you cross-offshore and clean conditions. Energy is very strong at 2948. This is expert territory – big, powerful, and clean. Then Monday the 7th morning is glassy – SE breeze at 5 km/h (3 mph), 7ft of SW swell with a 16-second period, and the energy is pumping at 2173. That’s an incredibly clean, lined-up reef wave. This is your second standout – glassy conditions, long-period groundswell, and the reef will be throwing proper walls.

The rest of that week stays solid but the winds get a bit cross-on or onshore, so pick your windows. Thursday the 10th morning still looks good with NE cross-off at 20 km/h (12 mph) and 7ft at 16 seconds – clean enough, but the energy is up at 3222 so there’s plenty of push.

Further out, Saturday the 12th and Sunday the 13th get huge – 12ft to 13ft swell, but the winds are onshore or cross-onshore and strong. That’s a big, unruly mess. Only for the hardcore, and even then, it’s more of a kite-surfing kind of day at a beach setup.

Overall, your best bets are Sunday morning the 30th of August for a solid, clean 8ft swell, and Monday morning the 7th of September for glassy 7ft lines. Crowds are likely at Watermans, so get in early.

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.
