The Lowdown
G’day, Rusty here with a blunt one. Over the next 16 days, Maslin Beach is flat as a pancake. There’s no decent surf coming, so don’t bother checking the forecast every morning.
Starting Wednesday the 19th of August, we get a tiny pulse of 1.3m from the WNW, but the period’s a weak 5 seconds, combined energy only 83, and a 35 km/h NW cross-on wind wrecks it. After that, it’s downhill. From the 20th, swell drops to 3ft or less, periods shrink to 4 or 5 seconds, and energy falls into the 30s and 20s. By the 22nd, we’re talking 0.3ft to 1ft, with energy in the teens.
The cleanest conditions pop up late in the run – on the 29th and 30th, we get a light cross-off breeze, and on the 2nd and 3rd of September, it goes glassy. But the swell is a joke: 0.3ft to 0.7ft, with energy in single digits. You’d be floating, not surfing.
Water temp’s about 57°F, right around average for the season.
No standouts here. This is a dry spell for the area, but it won’t last forever. Forecasts change, so keep an eye out, but for now, grab a coffee instead.
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.
