The Lowdown
G’day, Rusty here.
Well, I’ve had a good look at the charts for Maslin Beach over the next couple of weeks, and I gotta be straight with you – it's a pretty grim run. There's not a single session in the 16-day window that I’d call a proper surf. The whole forecast is essentially a write-off for paddle surfing, so if you’re hanging for a wave, you might want to look elsewhere or pick up another hobby for a bit.
The issue is a persistent lack of any decent, rideable swell. We’ve got mostly tiny scraps of energy, all below 1 to 2 ft, with short periods that won’t produce anything worth paddling for. Even the one small bump we see on Sunday the 2nd of August – a 4 ft to 5 ft mix from the NNW and WNW – gets absolutely hammered by fresh onshore winds, making it a lumpy, choppy mess. The combined swell energy hits 109 (moderate) that afternoon, but the wind ruins it completely.
Things get a little glassy and clean around Thursday morning the 6th of August, with some 3 ft swell from the WSW and light winds, but the period is only 5 seconds, so it’s just weak, bumpy shorebreak – not surfable. That’s as close as we get to a highlight, and it’s not saying much.
For the rest of the outlook, it’s a lot of flat spells, strong onshore winds, and poor surf conditions. If the swell was bigger and the wind was howling, this setup would look more interesting for kite surfing than paddle surfing. But as it stands, even that would be a stretch.
Hang in there, but don’t hold your breath. Forecasts change, but this one’s a stinker.
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.
