The Lowdown
G’day, Rusty here.
Well, I’ve looked over the whole sixteen-day window for Maslin Beach, and I’ll be straight with you – it’s a tough stretch. There’s a bit of a pulse right at the start, but it comes with a lot of drama.
We kick off on Saturday the 5th of September. A 7ft swell from the W pushes in, but it’s getting smashed by a howling 25 mph westerly. The combined energy is high, hitting 430 to 628, but with that wind it’s going to be a complete mess. That’s a big, raw swell with a short 7-second period – not the kind of wave you paddle out for unless you’re looking for a beating. This is a beach and reef setup, and with conditions this poor, it honestly looks more interesting for kite surfing than paddle surfing.
That swell fades fast. By Sunday the 6th, we’re down to a tiny 1ft from the WSW, with a moderate combined energy of only 31. The wind eases to a light 6 mph cross-onshore, but there's just not enough push to do anything with it.
From Monday the 7th right through to the end of the forecast on Saturday the 20th of September, we’re looking at a long, dry spell. Nearly all the records show swell heights between 0.3ft and 2ft, with combined energy readings mostly in the single digits or low teens. There’s no real swell to speak of.
There are some lovely, clean days in there – like Tuesday the 8th morning with glassy conditions, and Friday the 11th with a gentle offshore – but with bugger-all waves, it’s just a flat, pretty ocean.
The one little blip is on Thursday the 9th of September morning, when a 3ft SSE windswell shows up with a very short 4-second period and a combined energy of 31. The wind is a 19 mph cross-offshore, so it’s clean, but the period is so short it’ll just be lumpy, bumpy close-outs.
Honestly, there’s no standout here. Nothing is consistent, and the whole forecast is a blank run for surfable waves. This is one of those periods where you park the board and wait for the next weather pattern. Forecasts can change, but right now, it’s a hard pass.
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.
