G’day, I’m Rusty, and I’ve been watching the charts for your local break. I gotta be straight with you—this 16-day stretch from July 11th to July 26th is a total bust. There’s nothing worth paddling out for, so put the board away.
Let’s start with Saturday, July 11th. Maslin Beach has a 6-foot northwest swell, but it’s a short, weak period of 6 seconds, with combined wave energy in the moderate range. The wind is howling out of the northwest at 30 mph, straight cross-onshore. It’s a mess. That afternoon, it jumps to 8-foot from the west-southwest, with 30 mph onshore winds and even more energy—still poor quality. Anything over 5 feet gets tough for beginners, and with that wind, it’s just blown out.
Sunday the 12th and Monday the 13th keep going with rain, onshore winds, and small, weak swells around 3 to 5 feet, periods of 5 seconds. The energy drops way off by Monday, so it’s weak and choppy. Tuesday the 14th, the swell fades to 2-foot and 3-foot, but the wind is still cross-onshore. From Wednesday the 15th onward, it gets tiny—0.5-foot to 1-foot—with glassy mornings but no wave to catch. The energy is in the single digits.
There’s a small bump on Sunday, July 19th, with a 5-foot northwest swell, period 6 seconds, moderate energy, but strong cross-onshore winds at 25 mph ruin it. After that, it’s back to small wind swell under 3 feet for the rest of the run. The last few days, July 25th and 26th, are just 0.5-foot to 1-foot with onshore breezes—totally flat.
This is a normal dry spell for the area. Maslin Beach is a beach and reef spot that’s inconsistent, so when the weather locks in like this, you just have to wait. If you’ve got a kite, the windy days might be fun, but for paddle surfing? Not a chance.
Keep an eye on it, forecasts can change, but for now, it’s a no-go.

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.
