The Lowdown

Alright, let’s talk about Maslin Beach. I’ve looked over the next 16 days, and honestly, this stretch is a tough one for us. The surf is going to be either flat or tiny for nearly the entire run, and when there is a little bump, it’s generally messy. We’ve got a long, quiet spell ahead.

Right now, the outlook is rough. Starting from today, there’s barely a ripple. The water temp is sitting about average for this time of year, so no surprises there. The swell is just not cooperating.

For the first week, from the 6th through to the 12th, the swell is tiny, mostly around 0.3ft to 1.0ft from the WSW or SW. The combined energy is weak, values like 31 and 9, which is barely a pulse. The wind is a mixed bag with some glassy or clean moments, but with no swell, it doesn’t matter. We’ve got a few days of offshore or cross-off flow, like on the 11th with a glassy morning, but the swell is only 0.3ft. It’s just not worth paddling out.

We hit a bit of a spike on the 14th, where the swell from the WNW bumps up to 3ft, and the combined energy jumps to 43. That’s the biggest we see for a while, but the period is a short 5 seconds, and the wind is cross-on or onshore, turning it into a choppy mess. Poor surf conditions all the way. The morning of the 14th has light cross-shore wind, but that little pulse of swell is just too weak and short-period to make anything decent.

The 18th sees another pulse, with a 4ft swell from the north on Friday morning, but the period is a pathetic 4 seconds, and the wind is howling onshore at 19 mph. The combined energy reaches 52, but it’s just blown-out, onshore junk. Not a surfer’s wave. That’s the biggest height we see, but it’s a total write-off for paddle surfing. The setup here is a beach and reef, but with that strong onshore wind and short-period swell, this is more of a kite-surfing day than anything else.

The 19th and 20th are similar – fresh, lumpy cross-onshore winds and tiny, weak swell. The 21st finally shows a glassy morning with a light onshore, but the swell is gone again, down to 1.0ft. That afternoon, the wind swings onshore and the energy is only 19.

There is no standout session here, not one. The entire 16-day window is a write-off. The best you could hope for is a quick, knee-high dribble on the 14th morning if the wind stays light, but it’s inconsistent and the period is short. For a beginner spot, the 4ft on the 18th is too big and messy for learning.

Maslin Beach is a pretty exposed spot, looking for a SW swell, but it’s just not getting any love this run. This is a classic quiet spell for the area. Stay patient; it’ll change.

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.
