The Lowdown
G’day, Rusty here.
Well, I’ve got to be straight with you—this is a tough one for Maslin Beach. Honestly, looking over the next 16 days, there’s just nothing worth getting excited about. The whole stretch is a write-off for decent surf. We’ve got a gap right from the start, and it’s not a short one either. The first few days are all blown out with strong northerly winds up to 25 mph, and even when a bit of swell shows up, the wind just ruins it. The wave energy is weak to moderate at best, with the combined swell energy peaking at 494 on the 12th of August Wednesday morning, but with a strong onshore wind, it’s just a messy, lumpy windswell.
The water temperature is about average for this time of year, nothing unusual there.
We get a few days of glassy conditions around the 14th and 15th of August, but the swell barely reaches 1.0 ft, so it’s a flat, clean lake. Not a wave to be had. Then from the 16th of August onwards, we’re looking at tiny leftovers from a long-period SW groundswell—periods of 13 to 16 seconds—but the heights are only 0.3 ft to 0.7 ft. The long-period swell is there, but it’s a whisper, not a roar. The wind is light and offshore at times, which would be beautiful if there was any water moving.
This is a beach and reef setup, and with the lack of swell and the poor conditions on the bigger days, it’s not even worth a paddle. The only real standout here is just how consistent the lack of surf is. It’s a blank run, plain and simple.
Hang in there, the forecasts can change, but for now, leave the board at home.
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.
