The Lowdown
Alright folks, Rusty here. Let’s look at what’s coming up for Watermans.
We’ve got a solid run of surf on the way, but it’s a mixed bag with the wind. The good news is there’s plenty of size and energy, but you’ll have to pick your windows carefully because the onshores are going to mess things up for a few days in the middle.
The week kicks off with a bang on Thursday the 27th. There’s a big 10ft swell from the WSW, but the morning is a write-off with a strong 19 mph crosswind turning the surface into a lumpy mess. The afternoon cleans up a bit with a cross-off breeze, but it’s still marginal. The energy is massive though, with a combined reading of 3326. The water temp is sitting at 65°, which is pretty normal for this time of year.
Friday the 28th is smaller, dropping to 6ft, and the wind is still a moderate cross-off. It’s clean but not exciting. The energy drops to 1103. The standouts really start on Saturday the 29th. Morning has a small 3ft swell from the WSW, but the wind goes offshore from the ESE, and with a very long period of 19 seconds, it’s going to be clean and lined up. The energy is moderate at 813. The afternoon on Saturday is the best of the whole outlook. The swell jumps to 6ft, still from the WSW, with a 19-second period, and a moderate offshore breeze. This is proper groundswell, and the combined energy hits 1940. This is for experienced surfers, but it’s going to be excellent.
Sunday the 30th is another cracker. The swell holds at 8ft from the WSW, and the afternoon turns glassy with a NNE wind at only 3 mph. That’s as good as it gets for clean conditions. The energy is very strong at 3057. This is the standout session.
Then the wheels come off. Monday the 31st through to Friday the 4th of September sees onshore winds and poor conditions. The swell stays solid, between 7ft and 8ft, but it’s all blown out. The energy is still high, hitting 2774 on Thursday, but it’s no good for surfing. This stretch is more for the kite crowd.
The second week starts to look promising again. Saturday the 5th of September has a clean morning with a 6ft WSW swell and a light offshore from the East. The energy is moderate at 1210. Sunday the 6th is smaller and a bit messy.
Monday the 7th of September is a real highlight for the second week. Morning brings a clean 7ft swell from the SW, with a light offshore from the ESE. The energy is strong at 1544. This is a long-range promise, so keep an eye on the forecasts. After that, the wind turns onshore again and the quality drops off through to the 11th of September.
To sum it up, the absolute best windows are Saturday afternoon the 29th and Sunday afternoon the 30th. That glassy Sunday session is the one to circle on the calendar. The second week looks promising on Monday the 7th, but it’s less certain.
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.
