The Lowdown
Alright folks, Rusty here. Let’s be straight with you. We’ve had a look at Maslin Beach for the next 16 days, and to be honest, it’s a pretty lean stretch of surf. The forecast is showing a whole lot of flatness and ordinary conditions, with only a brief moment of interest right at the end.
The first couple of weeks are dominated by tiny, weak swell. You’re looking at swell heights mostly under 1 foot, often with wind chop or cross-shore breezes messing it up. The combined wave energy barely gets into double digits for most of it, staying well under 100 in the early days. The water temp is sitting around 58°F, which is bang on average for this time of year, so nothing unusual there.
The pattern is a long, drawn-out gap. From the start of the period through to the 12th of September, it’s essentially a write-off. There are days with a little bit of wind swell, like Tuesday the 1st of September pushing 4 feet, but the period is a short, gutless 5 seconds and the wind is a messy cross-shore. It’s poor surf conditions right through – no recommendations at all.
We finally get a flicker of life on Sunday the 13th of September. The morning sees a 5-foot swell from the north, with a period of 5 seconds. The wind is a light cross-offshore, so the surface will be clean. The combined energy jumps to 137 (moderate). By the afternoon, it improves a touch: the swell nudges up to 6 feet from the west, the period stays at 6 seconds, and the wind goes glassy. The energy hits 212 (moderate). The water temp data is missing for that day, but overall it’s still described as “surfable but very ordinary.” It’s a beach and reef setup, so that glassy afternoon wind will be the best chance for a few clean, if short-period, waves. With the swell over 5 feet, it’s a bit much for beginners, and the crowds at Maslin Beach are "often" around, so expect company.
That’s really the only window. The day after, on Monday the 14th, the wind picks up again and the quality drops back to poor. A short, sharp spike and then it’s gone.
So, if you’re desperate for a paddle, aim for the glassy afternoon of Sunday the 13th. It’s the only standout, and it’s not a world-beater, but it’s something. For the rest of the run, leave the board in the shed.
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.
