The Lowdown
Alright, Rusty here. Let's take a look at what we've got for the next couple of weeks.
Honestly, mate, it’s a pretty quiet stretch for Maslin Beach. We’re looking at a real flat spell to kick things off, and it takes a good while for any real energy to show up. For the first week and a half, we’re talking tiny, weak dribble – not worth paddling out for. There’s a long gap of days with next to nothing on offer. The water temp feels about average for this time of year.
There's a bit of a pulse trying to build around the 24th of July, but it’s a short-period wind swell with strong cross-shore winds making it messy. Not a surfer’s wave, that one. That setup at a beach and reef break like Maslin looks more interesting for kite surfing than paddle surfing, to be honest.
The only time we start seeing something that could be worth a look is right at the tail end of the forecast. Come the 29th of July, the swell bumps up to 3ft from the WNW, but the wind is howling from the Southwest at 15-16 mph, hitting as a cross-onshore. The combined energy is 49 (moderate), but with that wind and short period of 4-5 seconds, it’s going to be lumpy and choppy. Not ideal, but at least there's some water moving.
That 29th is probably the best on offer, but that's not saying much. It's more of a "check the cam and hope for a lull" kind of day. The rest of the period into the 31st just stays small and ugly with onshore wind. Nothing here to get excited about.

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.
