The Lowdown
Alright, let me tell you about the surf coming up for Watermans. Right now, the ocean is pretty messy. It's a mix of clean and lumpy with a small, weak 5ft swell from the WSW, but the south wind making it cross and bumpy. It’s not really doing it for me today. You’d be better off waiting.
Monday the 24th of August is where the fun starts. The swell is building to a solid 7ft from the WSW, and the period is a nice long 14 seconds – that's proper groundswell. The wind goes glassy in the morning. Absolutely clean, rippable conditions. The energy in the water is strong (1933). This is a great window for experienced surfers who know the reef; the size will be pushing it for beginners. The water is about average for this time of year.
Tuesday the 25th sees the wind turning onshore from the NNW, 20 km/h. The surf chops up, and the quality drops off hard. Wednesday the 26th is a wildcard. The swell jumps to a massive 13ft from the WSW with a very long period of 19 seconds – the combined energy is over 10,000, which is huge. The morning is messy with a cross-shore wind, but the afternoon looks incredible. Glassy conditions, zero wind, and that massive groundswell stacked up. That’s expert-only territory – huge, powerful lines. Not a spot for the faint of heart.
Thursday the 27th backs off a bit to a 10ft swell from the WSW, with the wind blowing cross-offshore from the SSE. The conditions will be clean, but the wind is fresh at 30 km/h, creating a bumpy texture on the face. The energy is still very strong (4670).
The following days drop in size but stay clean. Saturday the 30th of August brings a nice 8ft WSW swell with a 17-second period and light cross-offshore wind. The surf looks excellent, clean, and well-shaped, with moderate energy (3473).
Looking further out, Thursday the 3rd of September sees an offshore wind from the ENE with a 7ft WSW swell. Clean, empty-feeling lines. And then the forecast goes a bit crazy for Sunday the 6th of September. There’s a massive 21ft groundswell predicted from the WSW, energy reading over 22,000, with completely glassy conditions. That’s absolutely enormous and far too big for a paddle session at this reef break. That setup looks way more interesting for a downwinder or a tow session than a standard surf. That’s deep into the forecast, so things can change, but if it holds, it’s a spectacle.
So, the standout for me is Monday 24th August morning for the clean, powerful groundswell. And keep an eye on Wednesday 26th afternoon for a real expert session. Otherwise, there are plenty of smaller, clean windows in between.

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.
