G’day, Rusty here. Look, I’m gonna level with you – this next couple of weeks at Maslin Beach is a proper flat spell. We’re looking at a long stretch of tiny, unrideable surf right through until around Saturday, July 11th, with the odd little bump barely hitting the knee. It’s a pretty grim run for a paddle surfer, so if you’re itching to get wet, I’d honestly be looking at other hobbies for a while.
The first real sign of life shows up on Saturday, July 11th, but it’s not good news. The wind whips up from the NNW at 22 to 25 mph, kicking a short-period 4 ft to 5 ft swell. The energy is weak to moderate, but with that wind tearing across the beach, it’s going to be a lumpy, messy cross-shore mess. This is more of a kiteboarding setup than a surf session – just blown-out chop.
Sunday, July 12th picks up a bit more size, with a 7 ft to 7 ft swell from the W and WSW. The period is still short, and it’s blowing onshore at 25 to 28 mph. The energy jumps to moderate, but it’s going to be a rough, blown-out wall of whitewater. Not a day for beginners at all.
Monday, July 13th is the biggest day of the whole outlook, with a hefty 12 ft swell from the WSW early, dropping to 8 ft by the arvo. The period is short, and the onshore wind is strong at 22 to 28 mph. The energy is strong. This is expert-only territory, and even then, it’s going to be a bumpy, washing-machine kind of day.
After that, it’s a slow fade into small, wind-affected dribble through the rest of the second week. There is a brief, glassy moment on the morning of Thursday, July 16th, but the swell is a pathetic 0.3 ft – flat as a tack. There’s another little window on Sunday, July 19th with a glassy 3 ft NNW swell, but that bumps up to a 4 ft onshore by the afternoon, and the window is tiny.
Honestly, mate, riding near-daily onshore slop and short-period swell is grim. The setup is a beach and reef, and the consistent spring-like water temperature of 59°F is about average for this time of year, but there’s nothing on offer to enjoy it. I wouldn’t even call any of this a standout – it’s a blank run. Sometimes an area just goes quiet, and this is one of those times. Forecasts can change, but right now, keep the board in the car for your next trip.
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.
