The Lowdown

Right, let’s have a look at what’s coming up for Watermans. It’s a reef break, exposed to the WSW, so it wants that proper south-west groundswell to work. We’ve got a bit of a rough start here, but the potential later on is bloody exciting.

The first few days are a write-off, honestly. Wednesday the 2nd and Thursday the 3rd are messy with onshore winds and marginal conditions. The water temp is sitting at 64°, which is about a degree and a half colder than usual for this time of year – a bit nippy, but you’ll warm up if you get a good one.

We finally get a clean-up on Sunday the 6th. The swell is a solid 10 ft from the WSW, with a period bumping up to 13 seconds, and the wind swings to a light cross-offshore from the S. The combined energy is strong (3310) and the afternoon looks even better with a 4/10 score. That’s your first real chance to get a wave without getting blown off it.

But the standout, and I mean the *real* standout, is Monday the 7th. The morning session is where it’s at. You’ve got an 8 ft groundswell from the WSW, a long 16-second period, and a light offshore breeze from the ESE. The wave energy is pumping (3977) and the conditions are clean. This is a proper session for experienced surfers – those long-period lines will be wrapping around the reef perfectly. The crowds at Watermans are often there, so get in early.

The run of good weather continues into Tuesday the 8th. Another 8 ft swell, 16 seconds, and this time the wind is offshore from the ESE all afternoon. Gentle offshore and clean – that’s your ticket. The combined energy is still strong (3636). Not quite the peak of Monday, but it’s a ripper.

Now, the second week gets interesting. Thursday the 11th of September (remember, that’s more than a week away) sees a big pulse of swell. 12 ft from the WSW, 17 seconds, and the combined energy is massive (6273). The wind is a cross-onshore, so it’s a bit lumpy, but there’s so much power in the water. This one is for the bigger boards and the stronger paddlers.

The absolute jewel in the crown, though, is looking at Wednesday the 16th of September. The finder is showing a massive 15 ft swell from the WSW, with a 16-second period, and the wind is totally glassy in the morning. The combined energy is off the charts at 9723. This is exceptional surf, but it’s for expert surfers only. At 15 ft, this is a serious, serious ocean. If you’re not 100% confident, give it a miss. If you are, this is the session of the forecast.

So, to wrap it up: the first few days are a frustrating wait. Sunday the 6th is the first clean option, but the true standouts are Monday the 7th and Tuesday the 8th for the best combination of size, period, and wind. Then, for the big-wave crew, that Wednesday the 16th is the one to circle on your calendar. Long-range, so don’t bank on it, but it looks absolutely bonkers.

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.
