The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
We’re looking at a solid run of swell at Watermans, a reef break that’s fairly consistent. The water is sitting at 64°, which is a bit colder than we’d normally expect for this time of year, so you might want an extra layer.
The first standout is shaping up for Tuesday, August 11th. The morning session is the pick of the bunch, with a 7ft WSW swell and a long 15-second period, giving those waves some real push. The wind is glassy, which is about as good as it gets for clean faces. The combined energy is moderate at 1885, so there’s plenty of punch. After that, it does get a little lumpy as the wind swings onshore in the afternoon. The water is a bit cold, but for clean lines, you’ll want to be on it early.
For a second standout, look to Wednesday, August 19th. This is further out, so it’s a promising one, not a certainty. The morning has a clean, cross-offshore breeze from the NE, with a solid 12ft WSW swell and a 16-second period. That’s serious groundswell energy, with a combined energy of 6525, so it’s powerful. This is big, powerful surf – over 8ft, so it’s strictly for the experts. The clean conditions will make it look epic. The afternoon gets a bit more onshore, so the window is the morning.
Thursday, August 13th is also worth a mention for a solid morning session. Clean conditions with a 8ft SW swell and a 17-second period. The energy is 3231, so the wave quality should be excellent for experienced surfers, though it’s a bit under the size of the 19th.
The middle of the run, from the 9th to the 15th, has some decent size but is often a bit choppy or cross-onshore. The real standout days are the 11th and the 19th.
There is a gap of poor conditions around the 16th and 17th of August, with really strong winds and messy surf, so leave the board in the car those days.
The crowds are noted as being "often" at Watermans, so expect some company, especially on the clean mornings.
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.
