The Lowdown
Alright, Rusty here. Let’s talk about Maslin Beach.
Honestly, mate, it’s a tough stretch ahead. For the next 16 days, the surf is looking pretty ordinary. There are long gaps where there’s just nothing worth paddling out for. We’re talking about a flat spell through the middle of the period that goes on for several days.
For the first spot on the books, Maslin Beach, we’re looking at a long, drawn-out period of weak conditions. The water temp sits at about 58°F, which is pretty average for this time of year, nothing out of the ordinary.
The first sniff of anything with a bit of oomph shows up on Saturday the 19th of September. We’ve got a 4ft swell from the N and NNW, but the wind is a whipping 19 mph cross-shore, tearing it up. It’s a lumpy mess with combined energy only in the weak range, so really, this is more of a kite-surfing show than a paddle-surfing one.
Beyond that, it’s pretty much just tiny, weak swell. There’s a 2ft pulse from the WNW on the weekend of the 13th and 14th of September, but the onshore wind turns it into a washout. The period is super short, so there’s no push or shape.
Honestly, nothing stands out. You’d be better off waiting for a better run of forecasts. This area tends to stay quiet when it goes blank, so don’t hold your breath.
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.
