The Lowdown
Alright, it's Rusty, and I gotta tell you, it’s a bit of a tough stretch ahead for our stretch of coast. We're looking at a pretty bleak 16-day window, and honestly, for the vast majority of it, the surf just isn't going to be worth paddling out for. We're talking a long, flat spell with only a few tiny bumps that barely register.
Let's start from the top. The first real chance at anything is Tuesday, September 15th, and it's not much to write home about. Maslin Beach is showing a tiny 2ft SSW swell, but it's got a nasty short period of just 4 seconds, and the wind is a cross-off from the SSE at 19 mph. With combined energy sitting at a weak (32), those waves are going to be weak and messy. It's a beach and reef setup, but with the wind and the anemic swell, this is really only going to interest the beginners, and even then, it's a struggle.
We then hit a massive dead zone. From Wednesday, September 16th all the way through to Saturday, September 26th, the swell is either non-existent or so tiny that it's not worth a second look. You'll see charts showing less than 1ft for days on end, with combined energy values barely making it out of single digits. There is a brief moment on Sunday morning, September 20th where the swell bumps up a touch to 3ft from the West, but it's blown out by 16 mph onshore winds and a short period of 5 seconds. That's a hard pass. Monday, September 21st is similar – a bit of 1ft swell from WSW, but the wind is messy and the energy is still low (30).
The only real standout, if you can call it that, happens on Tuesday, September 22nd. We get a couple of glassy windows. Tuesday morning has a clean, moderate offshore wind from the East at 16 mph, with a tiny 0.7ft WSW swell. Then Tuesday afternoon goes totally glassy with a NNE breeze at just 3 mph. The swell is still a pathetic 0.7ft, but for a brief few hours, the ocean will look like a mirror. It's not surfable, but if you were going to just sit and stare, that's your moment. The water temperature at the start of the period was sitting at 59°F, which is about normal for this time of year, so no surprises there.
After that, it's back to the doldrums. Wednesday, September 23rd through to the 30th shows a flat ocean, with combined energy values of 7 or less. There's a tiny blip on Saturday, September 26th with a 2ft North swell, but it's accompanied by choppy, cross-onshore winds, making it a complete write-off.
Look, this is a proper blank run for the area, and it's not unusual to see the ocean just shut down for a while. Forecasts can change, but right now, there's nothing on the table. Maslin Beach is just not happening. The entire 16-day window is dominated by periods of no surf, with the worst stretch lasting over a week from the 16th to the 25th. Keep the board in the car, but leave the wetsuit in the cupboard. It's not our season.
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.

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.
