The Lowdown
Alright, folks. Rusty here. Let’s break down what’s happening at Watermans.
The next couple of weeks have plenty of size, but the wind is going to control the story. The first few days are a bit of a dud, but there are a couple of golden windows if you’ve got the experience.
The first decent chance to get out is the morning of Sunday, August 2nd. The swell is a solid 7ft from the WSW, with a 14-second period. That’s a proper groundswell. The wind is a light cross-off from the NE at 6 mph, keeping the surface clean. The wave energy is moderate at 1390. It’s not the best of the week, but it’s a good, honest session for the experienced crew.
Now, the one to circle is the morning of Monday, August 4th. This is the standout. The swell is a strong 8ft from the WSW, with a very long 18-second period. That’s a ton of energy (4034) heading straight for the reef. The wind is glassy – dead calm from the WNW at 3 mph. For a reef break, that’s as good as it gets. The water is about 64°, which is a bit colder than normal for this time of year, so don’t skimp on the rubber.
The Tuesday, August 5th, morning is also a solid option. Another 8ft of WSW swell at 16 seconds, with a light cross-off breeze from the NNE. More clean, powerful waves for the experts.
After that, the wind turns ugly. From Thursday, August 6th onward, it’s onshore and cross-onshore, with gale-force gusts hitting on the 8th. The swell gets huge, pushing 18ft on the 9th, but the wind is cross-shore, making it a messy, blown-out affair. At that size, this spot is for experts only, and honestly, with the wind, it’s looking more like a kite surfing day than a paddle surfing day.
The second week is rough, with strong onshore winds and big, lumpy conditions. There’s a brief flash on the morning of Friday, August 14th, with a 7ft WSW swell and a 17-second period, but the wind is a messy cross-on. Not worth the effort.
So, the bottom line: the absolute best session is the glassy morning of Monday, August 4th. If you’re an experienced surfer, that’s the one. Tuesday morning is a close second. The rest is mostly a washout.
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.
