The Lowdown
G’day, I’m Rusty, and I’m lookin’ at Maslin Beach for the next 16 days, and honestly, it’s a long stretch of pretty quiet water. The first recommendation doesn’t show up until Monday the 25th of August, but before that, from now through to Sunday the 24th, there’s a real dry spell—most days are flat, with tiny 0.3ft to 1ft dribbles that aren’t gonna get your heart racin’. The wind is sometimes offshore or clean, but without any push, it’s just not worth wettin’ a suit. The start of the window looks like a total bust.
Now, the only time things get interestin’ is Monday the 24th of August, with a late-arvo bump that jumps to 7ft from the WSW at 7 seconds. The combined energy is solid at 420 (moderate), but the wind is a light cross-onshore with small ripples—it’s not perfect, and the program calls it marginal. That size, over 5ft, is gettin’ too much for beginners, and with short period, it’ll be a bit lumpy. The only other hint of size is Tuesday the 25th, with a morning 6ft from WSW, and the afternoon 7ft from SW. The energy is strong again at 255 to 424, but the wind is onshore or cross-onshore, and the wave comment still says poor. That kind of small to mid-range swell with onshore wind at a beach and reef spot might actually look better for kite surfing than paddlin’ a proper surfboard.
Water temp at the start is 57°, which is about 0.7° below average—nothin’ wild for this time of year, just a little crisp.
So, there’s no true standout here. The best on offer is that Monday afternoon on the 24th with the 7ft swell, and maybe Tuesday the 25th in the afternoon if the wind eases a bit. But honestly, it’s a lean run. The consistent nature of the beach means it tends not to stay poor forever, but for this window, you’re mostly waitin’ on a change. Keep an eye on the 24th and 25th for the biggest bumps, and for the rest, save your wax.

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.
