The Lowdown

Alright, mates, Rusty here. Let’s have a look at what the ocean’s got in store for us over the next couple of weeks. Right off the bat, this is shaping up to be a period for the experienced crew. The water’s sitting at 64°, which is a bit colder than we’d normally expect for this time of year, so you’ll want the thicker rubber.

The opening days are a bit of a write-off. Friday and Saturday are looking messy with strong, onshore winds and plenty of lumpy conditions. There’s a lot of energy out there, but it’s all over the shop. We have to sit through a rough couple of days before things start to fall into place.

The first real glimmer of hope comes on Sunday morning, August 9th. The wind drops right out to a light cross-on, and we’ve got a solid 10ft of WSW groundswell with a long 16-second period. It’s not perfect, but it’s the first decent window. The energy is moderate, sitting around 6347, so there’s some punch behind it.

After that, things go ugly again for a couple of days. Monday is blown out and Tuesday brings a massive spike in energy, up to a very strong 23714, but it's too big and wild for Watermans. We're talking 16ft of swell with a cross-off wind. The power is incredible, but it's a shambles for anyone without a big-wave gun and a death wish. Not the one.

Then, everything clicks into place. Wednesday morning, August 12th, is your first real standout. The swell has backed off to a very manageable 10ft, still from the WSW with a solid 16-second period. The wind goes light offshore (NNE) and it turns glassy. The water is clean. This is when the reef starts showing its magic. It's an exposed spot, so it's handling all that energy perfectly. This is one of the best windows on offer.

We have a few more days of average, cross-on conditions, but then the real jewel appears. On Monday, August 17th, we get another fantastic window. The morning has a clean 12ft WSW groundswell at 17 seconds with a light offshore wind, pushing the energy up to a strong 7911. But it's the afternoon that's the true standout. The wind goes totally glassy, the swell holds at 13ft, and the period stays at a very long 17 seconds. This is the pick of the entire run. It's exceptional out there. A word of caution: this is a powerful, long-period swell, so it will be plenty challenging. Crowds are often a factor here too, so get out there early.

The back half of the week gets messy again with strong winds. The following weekend, the winds finally swing offshore from the east on Saturday, August 22nd. Mornings will be clean with a moderate 8ft WSW swell, and the afternoon looks even better as the wind stays offshore. It's solid, clean, and a good way to close out the fortnight. It's not as big as the big days, but it'll be a lot more user-friendly.

All told, we've got two prime windows. The first is the gorgeous glassy day on Wednesday the 12th, and the big one is the epic Monday afternoon session on the 17th. The second week is looking more promising than the first, so keep your fingers crossed.

Stay stoked.

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.
