The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on offer for Maslin Beach over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a pretty bleak run for a while. We’re looking at a solid stretch of poor surf conditions, with nothing really worth paddling out for until well into the second week. The first proper sniff of anything rideable doesn’t show up until Monday the 28th of September, so that’s a good two-week gap with no real recommendations. It’s one of those spells where the beach just goes quiet.
For the first break we’ll talk about, Maslin Beach itself, the water temp is sitting around 59°F – that’s pretty normal for this time of year, nothing unusual there.
So, the only time we see any potential is on Monday the 28th of September. In the morning, we get a bit of a pulse from the south with a 6ft swell. That’s a decent size, but combined energy is moderate at 239 – enough to get your attention. The wind is light and offshore from the east, so the conditions are described as clean. But, and it’s a big but, the overall quality is still only rated as surfable but very ordinary. The swell period is a short 6 seconds, so it’s windswell, not groundswell – it’ll be a bit weak and jumbly. It’s a beach and reef setup, so that short period might make it a bit messy.
Honestly, for a beginner, that 6ft might be pushing it, but it’s not huge. The crowd factor at Maslin Beach is ‘often’, so you won’t be alone. The optimum swell direction is from the southwest, and this is coming from the south – close but not perfect.
Look, if you’re desperate for a paddle, Monday the 28th morning is your only real window, but don’t expect anything magical. The rest of the period is a write-off. It’s just one of those times where the ocean’s not cooperating.
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.
