Table - best surf conditions forecast for Maslin Beach over the next 16 days.
G’day, Rusty here, and I gotta be straight with you – it’s a tough stretch ahead for Maslin Beach. The whole 16-day window is basically a write-off for any decent paddle surfing. There’s a long, grim gap from now until the end of the period with nothing worth getting wet for.
The forecast is a constant battle with messy, onshore wind and choppy conditions. For a beach and reef setup that’s exposed to the swell, we’re just not getting the clean lines we need. The water temp is sitting at about 58°F, which is pretty normal for this time of year, so no surprises there.
You’re looking at Friday the 10th of July to start, with a tiny 0.3 ft swell from the SW – basically flat, and with a cross wind, it’s just poor. Saturday the 11th gets a pulse, but it’s a messy 10 ft with a near gale on it, way too big and blown out. That raw energy is huge (813), but you wouldn’t want to be out there.
There’s a bit of a window Wednesday the 15th morning where it goes glassy with a light N wind, but the swell is a pathetic 1.0 ft. The energy is tiny (11). It’s pretty, but you can’t surf it.
We see a spike again around Wednesday the 22nd of July with a 8 ft swell from the W (combined energy 732 to 810), but it’s accompanied by strong onshore winds. That’s expert-only, messy, and dangerous. The swell period is short, around 7 seconds, so it’s just a close-out, wind-blown mess.
Honestly, for Maslin Beach over the next couple of weeks, conditions look more interesting for kite surfing than for us paddle surfers. We’re in a blank run, and that’s pretty normal for this spot when the wind doesn’t play ball. Forecasts can always change, but for now, leave the boards in the shed.
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.
