The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up at Watermans.
First off, the water’s sitting at about 65°F, which is a bit colder than we’d normally expect for this time of year. Nothing crazy, but you’ll feel it.
We’ve got a solid stretch of surf on the horizon, but you’ll need to pick your windows. The early part of the week is a bit average, but there are a couple of absolute gems lurking further out.
Wednesday, July 29th: We kick off with a clean 3.3ft SW groundswell (17 sec period) in the morning under a NE cross-off breeze. It’s small but workable for beginners. The afternoon pushes up to 4.9ft SW, still clean, and the energy is ramping up. It’s not epic, but it’s a gentle start.
Thursday, July 30th: Thursday morning is clean again, 3.9ft SW swell (16 sec). The afternoon sees the wind switch to a light W onshore, which isn’t ideal, but the morning is the pick.
Friday, July 31st: Friday morning gets a bit bigger with a 5.6ft WSW swell (16 sec) and a cross-breeze. It’s clean enough, but the afternoon gets messy with onshore wind and a 6.9ft swell. Not the best.
Saturday, August 1st: Saturday morning is clean with a 7.9ft SW swell (15 sec), but the wind is cross-off, so it’s rideable. The afternoon gets choppier. This swell is pushing over 8ft, so it’s getting into expert territory.
Sunday, August 2nd – THE FIRST STANDOUT: This is the one to circle. Sunday afternoon we see a 6.6ft WSW swell (13 sec) with glassy conditions – flat calm, no wind at all. The water will look like a mirror. The energy is moderate, but the clean surface means you’ll get some long, smooth lines. This is a prime window for experienced surfers.
Monday, August 3rd: Monday morning is also glassy, with a 4.9ft WSW swell (14 sec). Clean and smooth. A great follow-up to Sunday.
Now it gets serious. From Tuesday, August 4th through Wednesday, August 6th, the swell pumps up hard, reaching 8.2ft to 11.5ft WSW. But the wind gets ugly – cross-on and onshore, making for choppy, lumpy conditions. These days are for the diehards or maybe the kites, not for a quality paddle session.
Friday, August 7th – THE SECOND STANDOUT: This is the big one. Friday morning we get a massive 14.8ft WSW swell (12 sec), but here’s the kicker – the wind is a light SSE cross-off, and it’s clean. The energy is absolutely pumping. This is a heavy, powerful swell, strictly for experts. It’s going to be a wild, memorable session if you’ve got the nerve.
Saturday, August 8th and Sunday, August 9th: Big, messy, and windy. Strong onshore winds and huge swell. Stay on the beach.
Monday, August 10th to Tuesday, August 11th: Swell stays big (6.6ft to 9.8ft) but the wind is mostly onshore or cross-on. Not worth the fight.
Wednesday, August 12th – THE FINAL BIG ONE: Wednesday morning we hit the peak of the run. A 13.1ft WSW swell (18 sec period, very long period groundswell) with a light SE cross-off wind. Clean. The energy is colossal. This is a serious, powerful groundswell. At a reef break like Watermans, that long period will produce thick, heavy barrels. Experts only. The crowd will be there, so get in early.
Thursday, August 13th: Thursday morning is still clean with a 11.5ft WSW swell (16 sec) and a light cross-off. Another good option for the brave.
The real standouts for the whole forecast are Sunday, August 2nd afternoon for the glassy, smooth 6.6ft surf, and Friday, August 7th morning for the raw power of a 14.8ft clean swell.

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.
