The Lowdown
Alright, grab a coffee, because we’ve got a long stretch of flat, messy days ahead. Honestly, the next couple of weeks look pretty grim for Maslin Beach. We’re not seeing any real windows where the stars align, so keep your expectations low and your wax fresh.
We start off with a bit of a whimper. Through the 1st and into the 2nd, there’s just nothing doing. Tiny, weak swells and a cross-onshore breeze that’s going to have the surface all chopped up. Forget the board, maybe bring a book. The energy in the water on the 1st is a paltry 8 units, and it barely gets better.
The middle of the first week, from the 3rd to the 7th, is a proper flat spell. We see wave heights mostly under 3ft, with periods under 8 seconds, and a lot of that is just wind slop rather than any real groundswell. There’s a hint of a longer period swell (15 seconds) showing up on the 7th, but the size is so tiny (0.3ft) it’s not even worth paddling out for. It’s the kind of energy you can see in the numbers – a paltry 13 to 15 units – it's just not happening.
The weekend of the 8th and 9th sees the wind really pipe up. We’ve got a strong breeze swinging onshore, and while the swell bumps up a bit – hitting 6ft on the 9th – it’s going to be a full-on wind-blown mess. The combined energy gets up to 232 units, but with that onshore wind and short period swell, it’s less about surfing and more about getting thrashed. It might actually look more interesting for kite surfing than paddle surfing if you’re into that sort of thing.
Now, here’s the one moment that nearly gets interesting. On the morning of the 10th, a pulse of swell shows up at 8ft from the WSW with a period of 7 seconds. The energy reading jumps to 514 units, which is the biggest we see in the whole stretch. The wind is only a gentle cross-onshore though, which is the best we’re going to get. But here's the catch: 8ft of short-period swell is going to be a heavy, fat, and closed-out wave. This is expert-only territory, and even then, with the onshore lump, it’s going to be a battle. Not a fun one. For the rest of that week, it just fades back into mediocrity – small, weak, and choppy.
The second week pretty much follows the same pattern. From the 12th through to the 16th, we’re looking at smaller swells, mostly under 4ft, and a lot of fresh to strong breezes coming from the west and northwest. There are a couple of clean-ish moments with light winds on the 15th, but the swell is just too small and short-period to be any fun. The energy readings during this stretch are consistently weak, mostly below 100 units.
So, there you have it. The honest truth is that there are no good surf options in this 16-day window. Maslin Beach is an inconsistent break, and this looks like one of its more extended blank runs. It’s not uncommon for the area, and it tends not to stay poor for too long, so forecasts can change. But for now, keep the board in the car and go find something else to do.
Keep an eye on that 10th – it’s the only day with real power, but it’s a mean, ugly kind of power. If you’ve got a boat and a tow rope, maybe. For the rest of us, it’s a waiting game.

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.
