The Lowdown
Alright, Rusty here. Let's have a look at what we've got for the next couple of weeks around Maslin Beach.
Right off the bat, I gotta be straight with you – it’s looking pretty grim. We've got a long stretch of poor surf ahead. The first real chance of anything rideable doesn't even pop up until Thursday the 3rd of September, and even that’s a rough one. From now until then, we’re looking at a few days of flat or tiny, messy junk.
For Thursday morning the 3rd, we see a bit of a pulse, with a 4ft swell coming from the W, but the wind is a cross-onshore from the SW at 12 mph, making for some choppy conditions. The combined wave energy is only moderate at best (104), so it’s not got much push. This one’s a write-off for a decent session.
We then hit another lull, with no real improvement until the following week. It’s looking like a proper dry spell.
Now, if you're desperate for a paddle, keep your eye on Sunday the 6th of September. The swell drops right off to a tiny 1ft from the WSW, but the wind turns magic. We get a light offshore breeze from the ENE in the afternoon, with a clean, glassy surface. The period’s a touch short at 9 seconds, so it’s not gonna have much punch, but for a longboard or a foamie, it might be the cleanest little ankle-snapper you’ll find all week.
The best of a bad bunch, if I’m being honest, comes mid-week. Wednesday the 9th of September is a standout for the wrong reasons – the swell is still tiny at 1ft, but the wind goes totally glassy both morning and afternoon. The wave energy is really weak (26), but if you just want to sit out there and enjoy the calm, it’ll be the cleanest water you’ll see all forecast. Not really a surf, more of a float.
Looking further out, into the second week, there are a few more days of clean, tiny conditions with offshore or cross-off winds, like on Sunday the 13th and Monday the 14th. But the swell barely scrapes 0.3ft. It’s a consistent pattern of nothingness, so don’t get your hopes up. This is a classic blank run for the area, and honestly, forecasts can change, but right now, the surf is taking a holiday.
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.
