The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Maslin Beach.
Truth be told, it’s a pretty grim stretch ahead. We’re looking at a solid 16-day window, but the first week and a half is basically a write-off. From now through to the 23rd of August, we’ve got nothing but tiny, weak slop and poor conditions. There’s a few days with clean, offshore winds, but the swell is barely a ripple – 0.3 ft with weak energy (1-9). It’s just not worth paddling out for. That’s a long, flat gap to sit through.
Finally, things start to stir on Monday the 24th of August. The swell suddenly jumps to 6 ft from the NW, with a short, weak period of 6 seconds. The energy is moderate (215), but the wind is a cross-shore at 16 mph, making it a lumpy cross-chop. It’s not great quality, but it’s the first real sign of life. The swell builds further on Tuesday the 25th, hitting 8 ft from the WSW with strong energy (594), but the period is still short at 7 seconds, and the cross-shore wind is up to 12 mph. This is expert-only territory – too big and messy for beginners, and the cross-shore wind will chop it up. Honestly, for a beach-and-reef setup like Maslin Beach, with that much wind and short-period swell, this setup looks more interesting for kite surfing than paddle surfing.
The standout here is a window of calm on Wednesday the 26th of August. The morning turns glassy with a light southerly breeze at 3 mph, and the swell drops to 1 ft from the WSW. It’s tiny, but the energy is weak (13) and it’s clean. That’s the best you’re going to get – a small, clean session for the log or a longboard. The water temperature is 57°F, which is about average for the time of year, so nothing unusual there.
After that, it fades back into tiny, inconsistent dribble through the end of the month. The 30th and 31st of August show some clean, glassy windows with 2 ft to 3 ft swell from the SW, but these are late in the forecast and less certain. So, keep your expectations low, but if you’re desperate, the 26th of August morning is your best bet for a clean, tiny wave.
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.
