The Lowdown
Alright, Rusty here. Let’s take a look at what’s on offer down at Maslin Beach.
To be straight with you, the next 16 days look pretty flat. We’re looking at a long stretch of tiny, weak waves that just aren’t going to get the job done. From now through to the start of September, the swell is mostly 0.3ft or 0.7ft, with a few bumps on the 25th and 1st of September that only reach 2ft or 3ft, but the period is a short, crumbly 4 to 5 seconds, and the winds are messy. The combined energy barely cracks 43 (moderate) on the 25th, and everything else is a weak, two-digit number. It’s a long, flat spell.
The first glimmer of hope doesn’t show up until the morning of Saturday, the 5th of September. The swell picks up to 4ft from the NNW, with a period of 5 seconds and a combined energy of 102 (moderate). The wind is blowing offshore from the ESE at 6 mph, which is clean. The water temp is 58°F, which is about average for the time of year. The wave comment says “surfable waves but very ordinary conditions,” so it’s not a standout, but it’s the only thing on the entire 16-day chart that’s even worth a mention. The break is a beach and reef setup, and it’s inconsistent, so don’t count on it firing. It’s a beginner-level spot, so maybe a longboard session for the keen.
After that, the swell fades again. The 6th and 7th of September serve up onshore wind and rain, with the 7th seeing fresh winds of 22 mph from the west and southwest, making it choppy and lumpy. Not worth paddling out.
So, to sum it up: the only real option is the morning of the 5th of September. It’s not a classic, but it’s the only wave in town. Keep your expectations low, and you might get a few.
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.
