The Lowdown
Alright, let’s get into it. I’m looking at the next 16 days for Maslin Beach, and honestly, I’ve got to level with you—it’s a bleak stretch. There’s nothing here that’s going to get the heart racing. Not a single standout wave in the whole window. The forecast is a long, quiet run of small, weak, or messy conditions, and the breaks rarely even show a pulse. For a spot that’s inconsistent at the best of times, this is a real lull.
The first real chance you’d even paddle out is on Saturday, August 10th, but even then, it’s a struggle. On the morning of the 10th, we’ve got a 6ft swell from the WNW, but the wind is howling straight onshore at 16 mph. The combined energy is moderate at 239, but it’s going to be a mess. Not worth the drive. That afternoon, the swell drops to 5ft, still onshore (W at 16 mph), and the energy drops to 157. Still poor.
Tuesday, August 13th morning shows a 6ft NW swell with clean, cross-offshore winds from the south at 9 mph. Energy is moderate at 179. That’s the best you’ll see, but it’s still rated as “poor surf conditions.” The period is a short 5 seconds, so it’s weak and lumpy. Not a quality wave.
Then Tuesday afternoon rolls in with a 10ft swell from the WSW, a period of 8 seconds, and strong energy at 919. That’s a big, powerful swell. But here’s the thing: 10ft is expert territory only, and with a short period, it’s going to be a washing machine. The wind is cross-offshore from the SSE at 12 mph, so the surface might be clean, but the size and power are going to be intimidating. Only for the very experienced.
Wednesday, August 14th morning: a 5ft W swell, clean offshore wind from the ESE at 6 mph, energy moderate at 121. Period is still short at 5 seconds. It’s surfable, but just barely. The afternoon is smaller and more crossed-up.
The rest of the 16 days is tiny—0.3ft to 2ft swells with no real push. A few glassy mornings, like on the 4th and 7th, but the water is tiny (0.7ft to 1.0ft). You’d be on a longboard or a foamie, and even then, you’d be scratching for a ride.
So, to be straight: there are no good surf options in this 16-day window. The breaks are inconsistent, and the few days with size are blown out or too big. For a spot like Maslin Beach, these blank runs happen. It’s not a place that fires all the time. The water temperature is about 58°F, which is a touch cooler than usual for this time of year (about 1°F below average), so you’ll want a decent wetsuit.
If you’re desperate, the cleanest, most user-friendly window is the morning of Tuesday, August 13th (6ft, clean cross-off wind), but don’t expect any magic. Otherwise, sit this one out and wait for the next pattern change.

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.
