The Lowdown
G’day, Rusty here. Let’s be straight with you—this is a grim stretch for Maslin Beach. The whole 16-day window is a flat spell, with barely a ripple worth paddling for. The best you’ll see is a tiny pulse on the 20th and 21st, but it’s not enough to get excited about. The first week is a write-off, and the second week doesn’t offer much more. This is one of those blank runs that’s more normal for the area, so don’t be too disheartened—forecasts can change.
Thursday 10th September kicks off with a tiny 0.3ft SW swell, period 9 seconds, and light offshore ESE winds at 12 mph. Wave energy is a weak 3, and the surf is rated poor. Clean but not worth suiting up.
Friday 11th is even smaller—0.3ft again, period 9 seconds, with light ESE winds at 6 mph in the morning turning onshore from the west in the afternoon. Energy drops to 1. Still flat.
Saturday 12th is the flattest day of the lot: 0.3ft SW swell, 16-second period, with glassy conditions in the afternoon. Energy is 10. The water temp is about average for the time of year, but honestly, there’s nothing to surf.
Sunday 13th sees a tiny bump to 2ft from the north, period 4 seconds—short, weak windswell. Energy is 14. Winds are light cross-on and then cross, so the setup is messy and small. No good.
Monday 14th to Wednesday 16th stays tiny, with swell 0.7ft to 2ft, mostly from the west or WSW. Periods are short at 4-9 seconds. Energy ranges from 10 to 21. The winds are offshore or glassy at times, but there’s just no wave to work with.
Thursday 17th to Saturday 19th is more of the same—0.3ft to 2ft, short-period, with energy between 2 and 17. Winds are cross or cross-off, but the surf is flat as a pancake.
Sunday 20th finally brings a little something: 3ft from the north in the afternoon, period 4 seconds. Energy climbs to 40. Winds are onshore from the west at 9 mph, so it’s chopped and messy. Still poor surf.
Monday 21st is the best of a bad lot. The morning has 3ft WSW swell, period 5 seconds, energy 37, with gentle cross-shore winds. The afternoon goes glassy with 3ft SW swell, period 5 seconds, energy 50. That’s the highlight—clean, glassy, but tiny and weak. If you’re desperate, you might find a knee-high wave, but don’t get your hopes up.
Tuesday 22nd to Friday 25th drops back to tiny 0.3ft-0.7ft swells, with energy below 10. Winds are mostly cross or onshore, with some rain showers. It’s a total flat spell.
Look, Maslin Beach is a beach and reef setup, inconsistent at the best of times, and this forecast is a dud. The water temp is about average for September. If you’re a paddler, this is a no-go. Kite surfers might find something in the stronger winds on the 20th, but for everyone else, it’s time to check the cams and wait for a change.
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.
