The Lowdown

Alright, it’s Rusty here. Grab a coffee, because this is a long one.

Look, I’ve got to be straight with you: Maslin Beach is in a pretty grim stretch right now. For the next couple of weeks, we’re staring down the barrel of tiny, weak surf, mixed-up winds, and very little to get excited about. This is one of those periods where the sand might be better for a walk than a paddle. There’s a big gap of flat, poor conditions before we see a real pulse of energy, so patience is going to be the name of the game.

From now through the end of August, it’s mostly flat dribble. Saturday the 22nd and Sunday the 23rd, you’re looking at ankle-slappers around 0.3ft to 0.7ft from the SW and WSW with weak, short-period energy (combined swell energy is only between 7 and 20). The wind is a messy cross or cross-on, so it’s not even clean. Honestly, the board stays in the car.

Through the week of the 24th, there’s a tiny bump on Tuesday the 25th morning, with a brief spike to 3ft from the SSW, but the period is a shocking 4 seconds (combined energy 25). It’s a windswell mess. That south wind blows at 12 mph, making it choppy and cross-off. Not worth the wetsuit, mate.

Things stay flat, glassy, and useless from the 26th to the 31st of August. You’ll see the odd 0.3ft glass-off on the 28th and 30th mornings, but there’s no energy behind it (energy values dropping to single digits). It’s a total flat spell for any surfer.

We finally see a glimmer on September 1st. Tuesday morning shows a tiny 2ft from the north, with 4-second period, and light cross-shore winds – that’s a clean little ripple (combined energy 16). Not a wave, really, but it’s glassy. The afternoon is 2ft from the NW, glassy again. It’s a nice day to be on the sand, but you won’t be standing up.

Now, here’s the one true standout in this whole outlook, but it’s a long way out. Mark your calendar for Saturday, September 5th. The morning brings a legitimate pulse: 4ft from the west, with a 5-second period and clean offshore easterly wind at 6 mph (combined energy climbs to 90). This is the best window of the whole forecast. The water temp is around 58°F, which is about average for the time of year here. The afternoon on the 5th gets bigger, with 7ft from the west and a 7-second period (combined energy hits 384 – moderate wave energy). That swell is real, but it’s onshore wind in the afternoon, and at over 5ft and pushing 7ft, it’s going to be a lot for beginners and better suited to those with some experience. It’s a shame the period is short, but on the morning of the 5th, with offshore winds, that 4ft west swell could offer a few fun, clean walls at high tide if it aligns right.

After that, Sunday the 6th drops off again into weak, wind-affected slop – 1ft with moderate cross-shore winds.

So, the call: the first two weeks are basically a write-off for any decent surf. The standout, and the only window worth planning for, is the morning of Saturday, September 5th at Maslin Beach. It’s a beach and reef setup, fairly exposed to the SW, and the optimum swell direction is SW, so this west swell might wrap in okay. It’s inconsistent, so be prepared for lulls, but that clean 4ft west with offshore east wind is your best shot. The rest of the time? Save the wax.

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.
