The Lowdown
G’day, I’m Rusty. Let’s look at what’s coming up for Maslin Beach – a beach and reef setup down here that’s pretty exposed to the southwest. To be honest, the next sixteen days are a real struggle. There’s not a single recommended session in the whole run, and the surf quality is consistently poor. The water temperature is sitting at 59°, which is about normal for this time of year, so nothing unusual there.
The first few days are a write-off. Wednesday afternoon the 2nd has a tiny 2ft swell from the west with a period of only 3 seconds, and a 12 mph onshore wind – that’s just messy. Thursday the 3rd morning sees a bit more size at 4ft from the west, but still onshore and really short period, and the combined energy is weak at 82. Friday the 4th is cross-shore and small, with a 1.0ft west-southwest swell in the morning, period around 9 seconds but only 22 energy. Not worth paddling out.
Saturday the 5th is the biggest of the week – 7ft from the west-southwest in the morning, period 7 seconds, and combined energy jumps to 485 – that’s moderate wave energy. But it’s onshore at 22 mph from the west, so the conditions are poor. That’s more of a kiteboarding setup than a surf session. The afternoon drops to 5ft but still onshore.
Sunday the 6th morning is glassy calm with a 1ft west-southwest swell, period 9 seconds, but it’s cross-shore and tiny. Combined energy is only 27. Still poor surf conditions. Monday the 7th and Tuesday the 8th have offshore and cross-offshore winds, but the swell is barely a ripple – 0.7ft or less. The energy is in the single digits. Clean, but nothing to ride.
From Wednesday the 9th through to the end of the period, it’s the same story: tiny swell, mostly under 1.0ft, with combined energy often below 10. There are some clean mornings with offshore or cross-off winds, like Wednesday the 9th with a 0.3ft swell from the southwest at 15 seconds period – that’s a very long period groundswell, but there’s just no height. Even the glassy morning on Monday the 14th, with a 0.7ft west-southwest swell, gives you nothing to work with.
Maslin Beach is inconsistent at the best of times, and this run is a blank. There’s no standout here – not a single session worth chasing. Hopefully the forecasts shift, because it’s pretty grim right now.

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.
