The Lowdown
Alright, let’s be straight with you: the next 16 days at Maslin Beach are a tough stretch. This spot’s already inconsistent and often crowded when it’s on, but right now there’s just nothing worth paddling out for. Water temp’s sitting at 58°F to start, pretty average for the time of year, so no surprises there.
From Monday 24 August right through to the end of the month, we’re looking at tiny waves – mostly knee-high or less, with combined swell energy barely reaching double digits (3–15). A few glassy mornings pop up, like Wednesday 26 August morning and Friday 28 August afternoon, but with swell at 0.3–0.7ft, you’re not going anywhere. The wind’s light and sometimes offshore, but there’s just no push.
Then we hit a dead zone into early September – similar story, small and messy. Nothing changes until around Monday 7 September, when a pulse of SW windswell tries to show up. Heights hit 7ft in the morning (384 combined energy – moderate), 6ft in the afternoon (240). But the wind’s a killer: fresh cross-onshore and onshore, lumpy, poor conditions. For beginners, anything over 5ft is a handful, and with that wind it’s just ugly. Even experts won’t enjoy it. The rest of the window fades back to tiny stuff with onshore breezes.
Honestly, this is one of those blank runs that’s more normal for this area – inconsistent breaks tend to have quiet spells. Forecasts can shift, but for now, I’d say keep the board in the car and wait for a better window.

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.
