The Lowdown
Alright, Rusty here, let’s talk about what we’ve got coming at Watermans for the next couple weeks.
Right off the bat, Monday morning the 7th of September is where it fires up. We’ve got a solid 8ft WSW groundswell, riding a 16-second period, and the combined swell energy is pumping hard at 3726 – that’s serious power. Water temp is 64°, dead average for this time of year. A light 6 mph SE breeze keeps it cross-off and glassy clean. This is strictly for the experienced crew – 8ft is way too big for beginners. The reef handles that long-period groundswell perfectly. Crowds are likely here on a day like this. Monday afternoon gets a bit messy with a moderate cross-shore chop, so get it in the morning.
Tuesday the 8th hangs in with similar 8ft swell and a cross-off ESE wind, though the morning breeze is 18 mph. The afternoon turns it on with a 15 mph offshore from the ESE, clean and groomed. Another top session for the experts. Wednesday the 9th the swell drops a touch to 7ft, but the morning has a strong offshore from the ENE at 22 mph – that’s well shaped but a solid paddle. The afternoon wind drops to 12 mph offshore, still clean.
Thursday the 10th the swell drops to 5ft, but a gentle 9 mph offshore in the afternoon makes for a clean, easy session. Friday the 11th is a mess – onshore wind from the NW, choppy and no good. Saturday the 12th and Sunday the 13th are onshore and rainy, with the swell jumping back up to 6-8ft but with W wind right on it – just a blown-out mess.
There’s a gap of rough conditions from the 11th to 13th. Monday the 14th brings another clean, light wind morning with a 6 mph NE cross-off, 8ft swell – the reef will be working nicely. The next few days through Wednesday the 16th have swell around 7-7ft but with cross to cross-on winds, so it gets increasingly choppy.
Thursday the 17th and Friday the 18th are blown out by strong cross-on winds. Friday the 18th morning shows a big 10ft WSW swell, 15-second period, combined energy of 5560 – massive. But the 9 mph cross-on wind is too light to clean it up, so it’ll be lumpy and for the brave only. From there it’s onshore and choppy through to the end, with one last big but messy pulse on Monday the 21st of 8ft from the SW with an 18-second period.
So the clear standout is Monday morning the 7th of September – big, long-period groundswell, light cross-off wind, clean and powerful. Tuesday the 8th afternoon runs it close. This reef can handle the heavy stuff, so if you know what you’re doing, those first two days are golden.
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.
