The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of south-west groundswell inbound for Watermans, a classic reef break. The pattern is a long-period pulse that arrives mid-week and hangs around, but the winds are going to be the real story. The standout session is Wednesday afternoon, 26 August, when the wind goes glassy, the swell pushes to 12ft with a 18-second period, and the energy is pumping at 7956. This is not for the faint of heart—this is expert territory. The wave quality is exceptional, and with that long period, the sets will be clean and powerful, peeling nicely down the reef. Crowds are often here, but on a swell this size, only the hardcore will be out.
Water temperature is about average for the time of year, nothing unusual.
The Wednesday morning, 26 August, is a write-off with a strong 25 km/h cross-shore and a 10ft swell that’s messy. You’ll be fighting a cross-chop. Thursday morning, 27 August, is even worse with 35 km/h cross-shore, so skip it. Thursday afternoon cleans up with a cross-off breeze and a 10ft swell from the SW, but it’s still only marginal.
Friday, 28 August, drops a bit in size, with 7ft in the morning and 6ft in the afternoon, both clean but weak energy. The real next highlight is Sunday morning, 30 August. The swell is 8ft from the WSW, 18-second period, and the wind is a light cross-off from the NE. This is excellent for experienced surfers, with a combined energy of 3164. It’s clean and punchy. The Sunday afternoon gets a light cross-on, so not as good.
Monday, 31 August, is a write-off with onshore wind and chop. Tuesday, 1 September, has a 8ft clean morning session but the energy is dropping. Wednesday morning, 2 September, is glassy with a 7ft swell, clean and excellent for experienced surfers, but the energy is moderate.
Now, looking further out, the second week has some promise. Thursday morning, 3 September, is glassy with a 7ft, 14-second swell from the WSW. Clean. Friday morning, 4 September, is clean cross-off with 7ft. Saturday morning, 5 September, is also clean. But the real late standouts are Monday, 7 September, and Tuesday, 8 September. Monday has 7ft to 8ft with offshore winds from the east, clean and consistent. Tuesday morning has a 10ft swell with a cross-off breeze, and Tuesday afternoon is the pick: 10ft, 17-second period, gentle offshore wind from the ENE, and a combined energy of 4565. This is excellent for experts. The 8th of September is about a week and a half away, so keep an eye on it—long-range but promising.
There’s a gap of a few days after the 10th where conditions look marginal, but until then it’s a good stretch.
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.
