The Lowdown
Alright folks, Rusty here. Let's break it down for Watermans. The next couple weeks are a real mixed bag, with some serious groundswell on the charts, but the wind is the key. If you can nail the windows and handle a bit of size, there's some proper good sessions to be had.
We kick things off on Thursday the 16th, and man, it's ugly. Heavy rain and a solid 6ft WSW swell is ruined by a strong cross-on wind. Don't even bother. Wait for Friday morning the 17th. The wind swings light cross-off, the surf cleans up to a nice 6ft from the WSW at a solid 13 seconds, and the water is a bit colder than average at 64°. That's a morning that'll set you right. Saturday the 18th goes massive, with a monster swell peaking at 13ft on Saturday afternoon – that's only for the experienced crew, especially with strong onshore wind in the morning. Sunday is still big and bumpy with cross-onshore winds, so not great.
The absolute standout, the one to circle on your calendar, is Monday morning, July 20th. The wind goes dead flat, glassy as a lake. The swell is a very manageable 6ft from the WSW with a long period of 13 seconds. This is a reef break, so that long-period groundswell is going to wrap in and line up beautifully. The conditions will be as perfect as they get. The only downside is the crowds are "often," so you know the lineup will be busy that morning.
Tuesday the 21st morning gives you another glassy window with similar 6ft swell, so that's a solid backup. The second week from the 22nd onward is a bit less consistent, but still has some promise. Wednesday the 22nd and Thursday the 23rd bring clean conditions with moderate offshore winds, and good 6ft to 7ft WSW/SW swells. The energy drops a bit later in the week, but those clear, offshores days still deliver clean, fun waves for the experienced guys.
Around the 28th and 29th, we see another notable pulse of swell. While the 28th is choppy, Wednesday morning the 29th is a real sleeper. Glassy conditions again, with a 4ft swell but an incredibly long 18-second period. That’s proper groundswell for this reef – long, clean lines, great for a quiet midweek session. The end of the month on the 30th and 31st is back to big, messy groundswell, with 10ft and 15 mph onshore winds on the 31st making for a poor finish.
The one session you do not want to miss is Monday morning, July 20th. That glassy, clean, chest-to-head-high swell with long period on the reef is the peak of the whole run. Tuesday the 21st morning and Wednesday the 29th morning are your backup options for when you need a clean fix.
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.
