The Lowdown
G’day, I’m Rusty, and I’ve been staring at this 16‑day stretch for Maslin Beach. You know what? It’s a real tough one. The first ten days are basically a write‑off — poor surf, messy winds, tiny swell. There’s a big gap with nothing worth paddling out for from Sunday afternoon the 2nd all the way through to Thursday the 13th. That’s almost two weeks of flat, choppy, or just plain ugly conditions. Then, right at the tail end, we finally get a flicker of hope.
The water temperature at Maslin Beach is sitting at 57°F, with a small anomaly of -1°F — so pretty much average for this time of year, nothing to worry about there.
Now, after a long, blank run, the one standout that finally breaks the drought is Friday morning, August 14th. The swell jumps up to 7 ft, coming from the southwest – that’s the optimum direction for this beach and reef setup. With a period of 7 seconds, it’s a short‑period swell, but it’s got some punch. The combined wave energy reads 337 – that’s strong, good energy. Best of all, the wind is light offshore from the east‑northeast, making for clean, lined‑up waves. This is definitely the best session in the whole forecast. It’s a bigger swell, so it’s more suited to intermediate and experienced surfers, but the conditions are golden. The crowds can be an issue here though, and with surf this good on offer, Maslin Beach is likely to get busy.
Later that same Friday afternoon, the swell drops to 5 ft with glassy conditions, but the energy is down to 161 and the comment says “surfable waves but very ordinary conditions” – so it’s not the same quality as the morning session.
After that, it’s back to dribble for the rest of the forecast. There’s a brief moment on Thursday morning, August 13th, with glassy conditions and 3 ft of swell, but the energy is weak (35) and the period is short – just not enough to get excited about.
So, if you’re after a wave, mark your calendar for Friday morning, August 14th. That’s your window. Everything else is a skunk.
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.
