The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for our local stretch.
Straight up, I gotta be honest with you – it’s a long, tough stretch ahead. We’re looking at a solid run of days with next to nothing worth paddling out for. For the first week and a half, from now through to early August, the surf is almost non-existent. We’re talking tiny, weak waves, mostly under 3ft, and the wind is all over the shop – cross-onshore, cross-shore, just not playing ball. The wave energy is dismal, barely cracking double digits for most of that time. It’s a real bummer.
There is a flicker of hope, but it’s a long way off. For Sunday the 9th of August, things start to get a bit more interesting. The swell picks up in a big way, swinging from the west. We’re looking at a solid 8ft to 10ft of swell, but here’s the catch – the wind is forecast to be a moderate cross-shore from the north. That’s going to put a chop on the face, so it’s not going to be the clean, peeling perfection we all dream of. The combined energy is strong, hitting 474 and then a hefty 1148 on Sunday afternoon, so there’s plenty of water moving around. But with the size and the wind, this is strictly for the experienced crew. The short period (6-8 seconds) means it’ll be a bit lumpy and sectiony, not the kind of groundswell that holds a nice line.
Truth be told, there’s no standout day in this entire 16-day window. The only real “event” is that Sunday the 9th of August, but it’s messy and for experts only. There’s a brief moment on Tuesday the 4th of August morning where the wind goes glassy, but the swell is pitiful at 1ft and from the WSW, so it’s just a flat, glassy lake. Not a surfer’s friend.
For the first break on the list, Maslin Beach – it’s a beach and reef setup, pretty exposed. The water temp is sitting around 58°, which is pretty normal for this time of year, no real anomaly there.
Look, it’s a blank run. Nothing to get excited about. The forecast can always change, but for now, leave the boards in the shed. For a beach and reef setup with this kind of strong onshore wind and lumpy swell, honestly, this looks more like a kite-surfing week than a paddling week.
Rusty.

A general guide to surfing at Maslin Beach can be found by selecting the local surf guide option on the grey menu.

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.
