The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Watermans.
Right off the bat, we’ve got a solid, persistent swell train aimed at this reef setup, but it’s not all sunshine and barrels. The water’s sittin’ at 64°F which is a touch cooler than usual for this time of year – about 2°F below average, so you’ll want a decent spring suit.
The week kicks off Sunday the 6th with a lumpy 8ft WSW swell, but a stiff 19 mph SSE wind is blowin’ cross-off, keeping things clean but messy. Honestly, it’s pretty marginal, and the combined energy is a thumping 2365 (moderate to strong), but the conditions just aren’t there for a good session.
Monday the 7th morning is where it starts to get interesting. The swell holds at 8ft from the WSW, but the wind drops to a light 6 mph SE breeze, still cross-off. The period jumps to 16 seconds, giving it proper groundswell grunt, and the energy climbs to 3726. This is solid, clean surf, but it’s over 8ft, so this is one for the experienced crew only. The afternoon sees the wind pick up again, making it less inviting.
Now, the standout window is Tuesday the 8th. Both morning and afternoon deliver offshore wind from the ESE at 16 mph, with the swell holding around 8ft to 10ft from the WSW. The period is 16 to 17 seconds, and the combined energy peaks at 4022 in the afternoon – that’s strong wave energy. This is the best on offer: clean, powerful, long-period groundswell hitting a reef. For sure, that long period might make it a bit tricky for the beachies, but on a reef like Watermans, it’ll be reeling off nicely. Big, clean, and powerful – only for the experts.
Wednesday the 9th is still good with fresh offshore winds, but the swell drops a little. Thursday the 10th sees the swell drop below 5ft, and the wind turns cross-off, making it weaker.
From Friday the 11th through to the weekend, it turns ugly. The wind swings onshore or cross-on, and the swell gets choppy. The 12th and 13th are write-offs with onshore wind and poor surf. Don’t bother.
Monday the 14th brings a surprise: a glassy morning with a 3 mph NNE breeze, clean as a whistle, with a 8ft WSW swell. Combined energy is 2460. This is a solid, clean day for experienced surfers, with no crowds likely in that light wind. The afternoon goes cross-shore and less appealing.
The rest of the second week is a mixed bag of smaller swell and onshore or cross-shore winds. There’s a notable pulse on Friday the 18th afternoon, with a massive 13ft W swell and a 17-second period, energy hitting 11966 – that’s very strong. But the wind is onshore from the WSW at 9 mph, making it sloppy. For the brave and the strong, there might be some bomb sets, but it’s gonna be a battle. Saturday the 19th is even bigger but with onshore wind – blown out and dangerous.
So, the pick of the whole 16 days is Tuesday the 8th, and then Monday the 14th morning as a close second. Everything else is a lot of wind and waiting.
Rusty out.

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.
