The Lowdown
Alright folks, it’s Rusty here. Let’s be straight up – this outlook for the next couple of weeks is a tough one. We’ve got a long, dry spell of flat to tiny, messy waves ahead, and honestly, there’s not a single standout session in the whole run. The first proper surfable bump doesn’t show until the second week, and even then, it comes with some serious caveats.
First 10 Days
For the rest of July and into early August, Maslin Beach (South Australia) is mostly a write-off. The water temp is sitting at 57°F, which is about 1°F cooler than average for this time of year – not a major anomaly, but you’ll still want a good wetsuit. The swell energy is weak all week, with combined energy readings struggling to hit triple digits (mostly between 1 and 98). Winds are all over the shop, mostly cross or cross-on, and the swell is tiny – under 3 ft for days. There’s a brief bump Tuesday the 28th with 6 ft swell from the west and a 6-second period, but with onshore winds at 19 mph making it lumpy, it’s a messy one. Wednesday the 29th drops back to knee-high mush. Thursday the 30th has a glassy morning (wind from SSE at 3 mph), but the swell is a pathetic 1 ft – just flat.
Friday the 31st to Sunday, August 2nd are all tiny, with swell under 3 ft and weak energy. Sunday the 2nd has a bit more size (5 ft from the NW, 5-second period), but the wind is a cross-shore 16 mph, so it’s choppy and uninviting. Monday and Tuesday (3rd–4th) are flat again, with combined swell energy dropping to single digits. The morning of Tuesday the 4th is glassy, but with 0.7 ft of swell, there’s nothing to ride. Not a single recommendation here, and that’s pretty normal for this stretch.
Second Week (August 5–11)
Into the second week, it stays flat through Wednesday the 5th to Saturday the 8th – tiny swell, clean mornings with light offshore winds from the east, but the waves are barely ankle-high. Sunday the 9th shows a bit more life: 4 ft swell from the north, but it’s short-period (4 seconds) and weak energy (58), with a fresh 19 mph cross-offshore wind. Clean, but weak and gutless.
Then Monday the 10th drops back to almost nothing with onshore wind and rain – ugly.
The only real event comes on Tuesday, August 11th. A big, lumpy swell pushes through: 12 ft from the WSW with an 8-second period – that’s a serious amount of water, with combined energy hitting a massive 1540. The problem? It’s cross-on at 12 mph, and this is a beach and reef break, so expect choppy, jumbled conditions. That size (over 8 ft) is for experts only, and even then, it’s marginal. The morning session is rated a 1 out of 10 – basically ugly but rideable for the brave. Tuesday afternoon drops to 8 ft, still big and messy. No standout here – just a big, angry day for the experienced crew.
So overall, this is a 16-day blank for most of us. Stay tuned – forecasts change, and it won’t stay this flat forever. But for now, the boards stay in the car.
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.
Maslin Beach is 13 km (8 miles) from the very large city of Morphett Vale. If you plan a holiday in Adelaide, look for hotels and other accommodation in Morphett Vale. Morphett Vale has rooms for a wide range of budgets as well as cheap car hire and transport links.
