The Lowdown
Alright, Rusty here. Let’s be straight with you – this is a tough stretch for Maslin Beach. The next 16 days are looking pretty flat and messy, with no real standout sessions to get excited about. We’re in a long run of poor surf conditions, so don’t be expecting much.
The first real chance for a wave is Sunday, August 2nd, but even then it’s a struggle. Morning sees a 4ft swell from the NNW, but it’s a short period windswell of only 5 seconds – not much push. The wind is a cross-shore from the north at 15 mph, chopping it up. Water temp is about 57°, which is a touch below average for this time of year, but nothing wild. The combined energy is weak, at 73. That afternoon, the wind swings onshore and ramps up, so it’s not worth paddling out.
The next sniff of something bigger hits Sunday, August 9th, with the afternoon showing a 6ft swell from the NNW, but it’s onshore gale-force winds. That’s blown-out chaos. The combined energy jumps to 189 (moderate), but it’s not surfable.
Monday, August 10th, sees the biggest swell of the period – 7ft from the W in the morning, with a combined energy of 440 (strong). But the wind is a near gale from the NNW at 31 mph, making it a cross-onshore mess. That’s kite-surfing wind, not paddling. Only experts should even think about it, and even then, it’s ugly.
After that, it drops right off. The rest of the second week is tiny – waves under 2ft, with onshore winds most days. The only glimmer is Friday, August 14th morning, with a 3ft from the SSW, 5-second period, and light onshore wind. Not worth the drive.
Honestly, there’s no standout here. If you’re desperate, the most consistent window is the 9th and 10th of August, but those conditions are for the brave or the crazy. Otherwise, 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.
