The Lowdown
Alright, Rusty here, lookin' at what we got.
We got a 16-day window, but it starts off rough at Watermans, a reef break. The water’s sitting at 64.2° which is a touch colder than normal for this time of year.
Friday the 4th is a mess. Swell is a solid 10ft to 11ft from the WSW, but the 19 mph cross-on wind has it all lumpy. Not worth the drive. Saturday the 5th is more of the same, a choppy, ugly mess.
You'll see a change Sunday the 6th. The wind swings cross-off, cleaning the surface right up. Swell is still a big 10ft from WSW, so it's a clean but heavy reef. Only for the experienced guys. Wave energy is pumping at moderate to strong.
The absolute standout is shaping up for Monday the 7th. That’s the session to circle. Swell drops to 8ft from the WSW, but the period stretches to a very long 16 seconds. That’s proper groundswell with a ton of grunt, pushing through with strong energy. Wind is gentle and cross-off, keeping the reef glassy. This is an excellent window for a good surfer. That long-period swell will wrap in perfectly.
Tuesday the 8th keeps delivering with similar 8ft WSW swell and the wind going fully offshore in the afternoon. Dreamy stuff.
From Wednesday the 9th, the size starts to fade through the week, dropping to the 4ft to 5ft range by the 10th and 11th, but conditions stay clean.
Then we hit a rough stretch from Saturday the 12th through Sunday the 13th. We get hammered with onshore winds at 25 mph and rain, with the swell spiking to a wild 14ft on Sunday. It's messy and dangerous. That’s kite-surfing or no-surfing territory.
After that storm clears, things try to settle. Monday the 14th has a big 13ft SSW groundswell, but it’s still cross-shore. The real gem in the second week is Tuesday the 15th morning. The wind drops to a light breeze, going cross-off, and the swell cleans up nicely at 7.8ft from the WSW. The energy is still solid, and it’s clean. That’s the pick out of the second week for sure.
Wednesday the 16th morning also offers a clean light offshore with a smaller 4.6ft SW swell – perfect for getting back into it. The week ends choppy and onshore again, and by Saturday the 19th it's blown out with gale-force winds.
Short Range ForecastLight rain (total 8mm), mostly falling on Sat night. Very mild (max 17°C on Sat afternoon, min 10°C on Sun night). Winds decreasing (fresh winds from the WSW on Fri morning, calm by Sat night). | Days 4-6 Weather SummaryMostly dry. Warm (max 21°C on Wed afternoon, min 10°C on Mon morning). Mainly fresh winds. | ||||||||||||||||||||

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.
