The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for the next couple of weeks. We've got a solid run of swell on the way, but it's not all plain sailing. The early part of the outlook is a bit of a mixed bag, but there's a couple of absolute rippers coming up if you can wait for them.
The first real sniff of action is at Watermans on Thursday morning, August 13th. It's a reef break, so it's more for the experienced crew. We're looking at a strong 7ft SW groundswell churning in with a long 16-second period, and the combined energy is thumping with 2299. The water is a bit colder than normal for this time of year, at 64°, about 2° cooler than usual. The wind is a light offshore from the ENE, which is going to keep things clean. It's a good session, but it's a solid-sized reef wave, so it's not for the faint-hearted.
The next few days are a bit of a tease. Friday morning, August 14th, has a clean 7ft SW swell with a light cross-offshore breeze, but the energy is still cooking. Saturday morning, the 15th, drops a fraction to 6ft from the WSW, but the wind is still favourable. It's all surfable, but nothing is screaming "drop everything and go."
Then comes the real standout. Tuesday morning, August 18th, is where it's at. The swell has jacked up to a thumping 13ft from the WSW, with a 16-second period. The combined energy is a massive 7171, and it's an exceptional forecast for the confident crew. The wind is a gentle offshore from the ENE, meaning it's going to be glassy and clean. This is a big, powerful reef wave, and it's a true expert-only session. The afternoon holds a solid 12ft with a gentle cross-offshore breeze, still very clean.
The forecast gets a bit rugged after that. The wind turns onshore and messy from Wednesday, August 19th, through to the end of the week, with a lot of poor conditions. The swell is still massive, pushing 10ft, but the wind is making it a washing machine. This setup is looking more interesting for a kite surfer than a paddle surfer, to be honest.
Looking further out, there's another really promising window. Tuesday morning, August 25th, is a very strong option. The swell is back up to a solid 10ft from the WSW, with a 16-second period and a combined energy of 4938. The wind is glassy, absolute perfection. It's an excellent session for experienced surfers, and the conditions are clean. The morning of Wednesday, August 26th, also has a clean 7ft swell with a light offshore wind, but it's not as big as the Tuesday.
The very end of the period, around August 28th, looks like it's going to get messy again with a massive 15ft swell and strong onshore winds. That's a skip.
So, the best of the best is that Tuesday, August 18th, morning session. It's a proper, heavy, expert-level day. The second standout is the glassy Tuesday, August 25th. Both are well worth a look if you're experienced.
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.
