The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s in store for Maslin Beach over the next couple of weeks. I’ve gotta be straight with you – it’s a tough run ahead. This stretch is looking pretty flat and messy for the most part, so don’t get your hopes up.
The whole 16-day window is a real struggle. We’ve got a massive gap of poor conditions right from the start. For days on end, there’s nothing worth paddling out for. It’s not until Sunday the 20th of September that we finally see a flicker of life, and even then, it’s a one-hit wonder.
The first real standout is that Sunday morning on the 20th of September. Maslin Beach will wake up to a glassy, clean surface with clear skies and a slight air. The swell will be a solid 7ft coming from the west, with moderate combined wave energy (388). That’s a size that’s only for the experienced crew – it’ll be well overhead for most. With that westerly swell direction and the beach and reef setup, it could offer some punchy lines for the lads who know what they’re doing. The water temp is at 59°, which is just about average for this time of year, so nothing unusual there.
After that brief highlight, it’s back to the doldrums. The following Monday the 21st sees a drop to tiny 1ft waves with weak energy, and that’s pretty much the story for the rest of the outlook. There’s a lot of onshore and cross-shore wind, and the swell just isn’t there to back it up. The second week is a write-off – small, weak, and inconsistent.
So there you have it. One morning on the 20th of September is your best – and really only – chance to score something decent. Keep an eye on the sky, because the forecasts can shift, but as it stands, it’s a long wait for a short window.
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.
