The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – this 16-day stretch for Maslin Beach is a pretty grim one. We’re looking at a long, flat run where the ocean just doesn’t want to cooperate. The first proper surfable day doesn’t roll in until Sunday the 13th, and even then, it’s a mess. So we’ve got a gap of nearly a week of nothing worth paddling for right from the start.
For the first few days, from Monday the 7th through to Saturday the 12th, it’s all tiny, weak swells. We’re talking 0.3ft to 0.7ft scraps with combined energy barely reaching double digits (17 is the highest early on). There’s a glassy moment Tuesday morning, the 8th, with a 0.3ft SW swell and a 10-second period, but it’s just too small to do anything with. You’d be floating more than surfing.
Then Sunday the 13th brings a pulse of 3ft swell from the north, but the period is a short, choppy 4 to 5 seconds. The combined energy jumps to 37-45, but it’s weak and messy. The wind is a fresh cross-shore, making it lumpy. It’s a beach and reef setup, so with that onshore influence and short period, you’re looking at bumpy, unsurfable conditions. Honestly, this is more of a kite-surfing setup than a paddle-surfing one.
The only real standout moment, and I’m saying this with a heavy heart, is the morning of Friday the 18th. We’ve got a 5ft NNW swell, the biggest of the whole period, with combined energy hitting 109 (moderate). The period is still a short 5 seconds, so it’s a windswell, not a groundswell. The wind is a moderate cross-shore, so it’ll be lumpy. It’s not a classic, clean session, but it’s the only bit of size we get. It’s still only for the more experienced crew, as that 5ft is pushing it for beginners.
The rest of the second week shows a few small pulses, like a 3ft NW swell on the 17th and a 4ft WSW swell on the 21st, but the wind is never truly clean. The morning of the 20th offers a clean 1.0ft with a gentle offshore, but it’s tiny. It’s a flat spell broken by a few average days.
This area is known for being inconsistent, so a blank run like this isn’t totally unexpected. Forecasts can change, but for now, keep the board in the car and the wax in the cupboard.
Rusty.

Information about the Maslin Beach Surf forecast
The above surf forecast table for Maslin Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Maslin Beach can be found by selecting the local surf guide option on the grey menu. Our Maslin Beach 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 (Maslin Beach) 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 Maslin Beach 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.
