The Lowdown
G’day, Rusty here. We’ve got a proper 16-day window ahead at Watermans, but it’s gonna take its sweet time to turn on. The first few days are a bit of a write-off – messy winds and lumpy, raw swell make for a frustrating start. After that, we see a real shift in quality, especially into the second half of next week, where things clean right up.
Thursday (3rd) is a no-go. Cloudy morning with a 9 mph cross-onshore breeze messing up a 8 ft WSW groundswell (period a long 15 seconds). The energy reading’s a moderate 2305, but it’s choppy as all get-out. Afternoon gets worse – stronger wind, poor conditions. Friday (4th) starts even uglier – 10 ft of swell but strong onshore wind and a 16 mph cross-on makes it lumpy. The afternoon calms a bit with a 9 mph onshore, but at 10 ft and 14-second period (very long period), this is big, powerful, and only for experienced crew. Even then, it’s marginal at best.
Saturday (5th) is another day to sit out – strong cross-onshore winds and rain showers. Sunday (6th) sees the wind swing offshore from the south, but it’s howling at 22 mph in the morning. The swell’s a solid 12 ft (3476 combined energy – strong), period 13 seconds. Clean but too big and windy for most. Afternoon eases a touch to 10 ft SW, still strong (3475 energy), but the cross-off wind keeps it clean – only for experts.
Now here’s where it gets good. Monday (7th) morning: 8 ft WSW swell (period 16 seconds – very long period groundswell), energy 3870 (strong), with a clean cross-off breeze from the ESE at 12 mph. The afternoon is the real standout: same size and direction, wind drops to a gentle 9 mph cross-off, and the call is *excellent surf for experienced surfers*. The water temp is 64°, about average for this time of year (anomaly -1°).
Tuesday (8th) is the pick of the bunch. Both morning and afternoon are absolute magic. 8 ft to 10 ft of WSW groundswell (15-16 second periods, energy 3728 to 4071 – strong to very strong), but the key is steady offshore wind from the E to ESE. Morning: 12 mph moderate offshore, clean. Afternoon: 9 mph gentle offshore, even cleaner. This is prime Watermans – big, clean, and powerful. This is the best on offer.
Wednesday (9th) keeps the offshore wind theme going with ENE breezes. 8 ft to 7 ft WSW swell (16-second periods), clean and excellent. Still fantastic, but the swell size eases a touch.
Things then taper off. Thursday (10th) sees the swell drop to 6 ft and the wind goes light cross-off – still a good clean session for experienced surfers. Friday (11th) gets smaller and wind turns onshore again – hard pass. Saturday (12th) is a write-off with a massive 10 ft to 12 ft swell and fresh cross-onshore wind, energy 5133 (very strong) – dangerous and messy. Sunday (13th) has 10 ft WSW swell but the wind is cross to cross-on, making it marginal.
Monday (14th) morning is a beautiful surprise: glassy conditions, zero wind, with a 7 ft WSW groundswell (14-second period, energy 1874). This is about as clean as it gets – excellent for experienced surfers. Afternoon gets a 16 mph cross-shore, spoiling it.
The last few days, Tuesday 15th through Thursday 17th, offer clean but small surf (4 ft to 7 ft) with offshore or cross-off winds. Not a standout, but still worth a paddle if you’re keen. Friday 18th fades to tiny 3 ft to 2 ft waves with onshore wind – time to wax the longboard or just go fishing.
Best on offer: Tuesday (8th) morning and afternoon hands down. 8 ft to 10 ft of WSW groundswell with steady offshore wind – that’s Watermans at its finest. Monday (7th) afternoon and Monday (14th) morning (glassy) are also worth a shout.
Overall, the first few days are a test of patience, but once that offshore wind locks in from Monday 7th afternoon through Wednesday 9th, it’s a proper window of quality. And that glassy morning on the 14th is a late-week treat.
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.
