The Lowdown

G’day, Rusty here. Look, I’ve gotta be straight with you – we’re in for a pretty bleak run of it at Maslin Beach. This is one of those stretches where the ocean just doesn’t want to play ball. We’re talking a solid 16-day forecast window, and the first proper surf recommendation doesn’t even show up until the 26th of August. That’s a massive gap of nothing but flat, junk, or tiny conditions. For most of the next two weeks, you’re better off doing something else.

Right now, through the middle of August, it’s all poor surf. Tuesday the 11th kicks off with a messy 4ft NW swell but a 19 mph NNW cross-wind just chops it to bits – combined energy is a weak 51, and that’s about as good as it gets for a while, which says it all. Wednesday and Thursday drop to knee-high dribble, and by the weekend we’re looking at ankle-snappers under 1ft with clean but utterly useless conditions. There’s a glassy moment on Monday the 17th afternoon, but the swell is barely a ripple at 0.3ft with a 13-second period – a ghost of a groundswell that’s just not making it in.

The whole second week stays flat as a tack. We get some clean, glassy mornings around the 20th and 21st, but again, the swell is 0.3ft to 1ft of pure nothing. The combined energy figures are in the single digits – that’s about as weak as it gets. The wind is light and sometimes offshore, but with no wave to push, it’s a cruel tease.

Then, finally, on Wednesday the 26th of August, we see a flicker of life. The morning brings a 6ft WSW swell, period a short 6 seconds, with a moderate N cross-wind. The combined energy jumps to 226 – that’s moderate energy, the only real spike in the whole outlook. But the wave comment still reads “poor surf conditions,” and that onshore cross-wind is going to make it lumpy and messy. This is for experienced surfers only, as 6ft with that wind state will be a bit of a handful and not at all clean. The afternoon drops to 4ft with a cross-on wind, so it’s not a standout by any stretch. It’s the only thing on the menu, but don’t expect any gems.

So, to sum it up: there is no true standout here. The best on offer is that Wednesday morning on the 26th at Maslin Beach, with a 6ft WSW swell, but the wind will be messy. The water temp is about 57°, which is pretty average for this time of year, nothing unusual. Maslin Beach is a beach and reef setup, inconsistent, and when there’s a bit of size like this, it’s more interesting for the kite crew than paddle surfing. The crowds can be around often, but honestly, with quality this poor, you’ll have the place to yourself.

Stay patient, mate. Forecasts can change, but right now, it’s a long blank run.

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.
