The Lowdown
Alright, let’s get into it. The long-range charts are showing some serious life for Watermans, but you’re gonna need a bit of patience. The first few days are just a warm-up, with the real meat arriving later on.
We start things off on Tuesday the 8th with a solid 8ft of WSW groundswell rolling in. The period is a long 16 seconds, which means real energy. Water is sitting at 64°F, which is a bit colder than normal for this time of year, so you’ll want the full suit. The ESE wind is offshore and keeping it clean, but this is a powerful wave for a reef, pushing well overhead. This is expert territory only. The energy is strong, clocking in at 3636. Wednesday the 9th eases slightly to 7ft, still with that lovely offshore flow and good 16-second period. It’s still a hefty wave, but the quality remains high for those who can handle it.
Thursday and Friday back off noticeably. We’re looking at 5ft dropping to 5ft. The wind goes cross-off and then cross, which takes the shine off. The period stays around 14-15 seconds, so there’s still some push, but it’s not going to be a classic. These are the intermediate days, where you’ll be fighting for the better set waves.
The weekend turns ugly. Saturday the 12th sees onshore WNW winds at 25 km/h and the surf bumps up to 6-7ft. It’s going to be a messy, blown-out shambles. Not worth the paddle. Sunday the 13th isn’t much better, with onshore winds making it lumpy and uninviting at 7-8ft.
Monday the 14th brings a reprieve. The morning has clean conditions again, with a light ENE offshore wind and 8ft of swell. The period is still good at 14 seconds, and the energy is strong. This is a solid, powerful day, requiring a bit of know-how. Then Tuesday the 15th is a standout. The morning is glassy. Absolutely flat calm with a light S wind, and the swell is still a solid 8ft with a 15-second period. This is the cleanest, most powerful surf of the first week. It’s going to be beautiful out there, but again, size and power make it one for experienced surfers only.
After that, the energy fades away for a while. From Wednesday the 16th through the 18th, we see the swell drop to 4-6ft, and the winds turn cross-onshore and onshore, with a period of strong breezes and messy conditions. This is a stretch to avoid. There’s a clear gap of a few days with nothing worth recommending.
Now, here’s where the long-range forecast gets interesting. We’ve got a major pulse of energy lined up. Saturday the 19th shows a rapid increase in size, jumping to 12ft, then 13ft in the afternoon, but the period is short and the wind is onshore. It’s going to be a raw, powerful, and messy ocean. Sunday the 20th, the swell remains huge at 13ft, but the period jumps to a very long 18 seconds. The wind is cross-shore and fresh, creating some lumpy conditions. It’s a beast, but not clean.
Then, on Monday the 21st, the stars align. The forecast shows 12ft of WSW groundswell with a massive 18-second period, and the wind is blowing offshore from the ENE at 25 km/h. The wave energy is exceptional, hitting 7076. This is the standout of the entire period. It’s big, powerful, and clean. A true expert-only day with some serious, grinding, open-ocean swells. The morning is the pick. Tuesday the 22nd still has 10ft of SW swell, but the wind goes more cross-off, and it starts to lose its perfection. The energy is still strong, but the magic is gone.
The final days of the window see the swell gradually ease off. Wednesday the 23rd is down to 7ft, with an onshore cross wind, making it less appealing. The size is dropping and the quality is fading. The big event is that Monday the 21st. That’s the day to circle on the calendar. It’s far out, so treat it as a promise with a bit of caution, but all the early signs point to the best surf we’ve seen in this whole run.
So, pad up for the big Monday and the glassy Tuesday in the first week. The rest is about patience and picking your moments.

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.
