The Lowdown
Alright, mates, Rusty here. It's a grim one, so I'll give it to you straight. This outlook for Maslin Beach is about as bleak as it gets. We are looking at a solid 16 days of poor surf, with not one single window where I'd tell you to paddle out. It’s a tough pill to swallow, but it happens. There are simply no good surf options in this forecast period.
The first few days are a write-off. We see some swell in the 4 to 6 feet range, but it’s all lumpy and chopped up with strong, cross-shore winds. The energy is there, reading as high as 238 on Monday, but it's all over the place and there’s no shape to it. It’s just messy.
After that, the size falls away dramatically. By the 14th, we’re down to just over a foot, and then it basically goes flat. The wind turns light and clean, and we even get a few glassy offshores, which would be perfect if there was a wave. But there isn't a ripple. The energy readings drop to next to nothing – it’s completely dead.
There’s a slight tease of wind-swell on the 21st, with a couple of feet of short-period northwest slop, but it’s still rated poor and offers nothing for a decent wave. After that, it’s back to flatness and more windy days.
Honestly, with this kind of weak, bumpy surf, the setup looks way more interesting for kite surfing than paddle surfing. For us, it’s just a waiting game. This kind of dry spell is more normal for the area when the conditions align this way, but it won't stay this way forever. Keep the boards ready, because forecasts can change.
Hang in there, and keep the faith.
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.
