The Lowdown
Alright, Rusty here. Let’s have a look at what we’ve got on the cards for the next couple of weeks.
Honestly, the outlook for the whole 16-day window is a pretty quiet one. It’s one of those stretches where the ocean just seems to take a nap. The first solid chance of anything rideable doesn’t pop up until Wednesday the 10th of September, but even then, it’s tiny. You’re looking at a gap of a few days with no real recommendations at the start, and then a long, drawn-out run of poor surf.
Wednesday 9th to Tuesday 15th September: Don’t bother getting the wetsuit on just yet. We kick off with some clean conditions from a SE wind, but the swell is basically non-existent at 0.3 ft. The combined wave energy is laughable (3). It stays like this for days - clean faces but zero push. We get a little spike in energy on the morning of Friday the 12th with a combined energy of 10 from a 16-second period SW groundswell, but the height is still only 0.3 ft, so it's more of a ripple than a wave.
Sunday 13th and Monday 14th: There’s a little shift as a northerly wind picks up, pushing some 2 ft swell from the N, but the period is super short (4 seconds). The energy climbs a bit to (13), but that short-period windswell with a cross-shore wind creates a messy cross-chop. Not worth paddling out for.
Friday 18th September: This is probably the most interesting day of the whole stretch, but it’s a long way off. On the 18th, the wind swings N, and we get a 3 ft swell from the NW with a short 5-second period. The combined energy hits a moderate 43. It’s still a bit bumpy from the moderate cross-shore chop, but at 3 ft, it might offer a few close-outs for someone desperate. Just remember, short period and choppy wind are a rough combo.
The One Standout – Saturday 20th September: If you’re holding out for anything decent, this is your day. On Sunday the 20th of September, the morning shows a 4 ft swell from the WSW with a combined energy of (104). That’s the only time in the whole forecast we see moderate wave energy. The period is still short at 6 seconds, so it won't be a classic groundswell, but the wind is very light from the NNW with slight airs. The afternoon turns glassy. For Maslin Beach, a beach and reef setup, it’s the cleanest window we get, and the only time the size gets close to something fun.
Crowds: Maslin Beach can get busy, and with the conditions being so poor for two weeks straight, expect that spot to get crowded if that 4 ft glassy window actually shows up.
To sum it up: save your energy. The only real chance for a surf is the morning of Saturday the 20th of September. The rest is a flat, choppy, or tiny mess. Wait and see if that forecast holds.
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.
