The Lowdown
Alright, Rusty here again. Let’s break down what’s happening at Maslin Beach for the next couple of weeks, in feet and Fahrenheit.
Honestly, it’s grim. There’s a big gap of nothing at the start, and the first real movement doesn’t show up until the 9th of August, and even then, it’s a mess. For the first week, from Monday the 3rd through Saturday the 8th, it’s all flat, tiny dribble. Swell heights are 0.3 ft to 1 ft, with combined energy all in the single or double digits (weak energy). Winds are mostly cross or cross-on, and the water temp is 57°, which is pretty average for the season. Not worth paddling out.
Then Sunday the 9th of August rolls in. The swell jumps to 8 ft from the west, period of 7 seconds, and combined energy of 595 (moderate energy). That’s a real spike in size, but it’s a short period windswell, and the wind is screaming from the WSW at 25 mph, cross-on, creating a choppy, ugly mess. At 8 ft, it’s expert-only territory, and the quality is poor. This is a day for the kite surfers, not paddle surfers. It drops to 7 ft in the afternoon with 19 mph onshore winds. Still bad.
The rest of the second week is a total write-off. From Monday the 10th onward, it’s back to tiny, weak swells (0.3 ft to 4 ft) with combined energy mostly under 100 (weak energy). Winds are a mix of cross, cross-on, and onshore. There’s a glassy moment on the morning of Tuesday the 18th of August, but the swell is only 1.0 ft from the west with a period of 4 seconds and combined energy of 4 – that’s dead flat. Not a single standout day.
No surf to get excited about here. A blank run like this is normal for the area when the angles don’t line up. Could change, but for now, it’s a hard pass.
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.
