Alright folks, Rusty here. Let’s have a look at what’s on offer up and down this stretch of coast.

Honestly, I’m looking at a pretty grim run of it for the next couple of weeks. There’s a whole lot of nothing happening, especially for the first few days. We’re looking at a long gap of poor conditions before anything even gets close to worth a paddle. The only break on the radar is Maslin Beach – a beach and reef setup, fairly exposed to the swell but pretty inconsistent. For a beginner-friendly spot, it’s been a tough stretch.

Let’s get into it. For the first few days, from Thursday the 9th into the weekend, it’s all flat and messy. Thursday morning has a tiny 0.3 ft southwest swell, with a light northerly cross-off breeze, but it’s just dead. Water temp is sitting around 59°, which is about normal for this time of year, so that’s not the issue. The issue is that there’s hardly any energy – the combined swell energy is a pathetic 4. By Friday the 10th, it’s still 0.3 ft with a cross-shore breeze, and the energy is still in the teens. Saturday the 11th actually brings a bit of size – 6 ft in the morning and 8 ft in the afternoon – but it’s a total write-off. That’s a strong cross-onshore wind from the northwest, swinging to the west-southwest, and the period is a short, choppy 5 to 7 seconds. The energy jumps up a bit (720 in the afternoon), but it’s just a messy, blown-out wall of water. For a beach break setup, this is more of a kite-surfing day than a paddle day.

Sunday the 12th stays onshore and lumpy, with 5 ft of westerly swell and a fresh onshore breeze. The energy is moderate (176), but the quality is all wrong. Then we drop right back off into the doldrums. Monday and Tuesday are small, weak, and mostly onshore, with energy levels dropping into the double digits. By Wednesday the 15th, we finally get a clean window – clear skies, light offshore easterly wind, but the swell is microscopic at 1.0 ft. The energy is just 12. It’s glassy and clean, but you’d be fighting for a ripple. That kind of clean, offshore window holds through Thursday the 16th and Friday the 17th, with glassy conditions on Friday morning, but the swell is still 0.3 ft to 0.7 ft. It’s a tease.

The next minor pulse shows up around Sunday the 19th. We get 4 ft to 4 ft from the west-northwest, but it’s a northerly cross-shore breeze, and the period is a short 5 seconds. The energy is moderate (85), but it’s going to be lumpy and cross-chop. Not great. After that, Monday the 20th through the end of the forecast is back to small, weak, and mostly onshore. The last real chance is on Thursday the 23rd, where we see a tiny 2 ft from the north with a gentle cross-shore, but it’s not enough to get excited about.

So, the only highlight in this whole 16-day window is the clean, glassy morning on Friday the 17th. It’s not a surf you’d rush out for, but if you’re desperate for a paddle and a bit of reflection, the light air and glassy water will be peaceful. The combined swell energy is only 1, so it’s really just a bathe. The best actual swell we see – the 8 ft on Saturday the 11th – is a total mess with strong onshore winds. For a beginner spot like Maslin, that’s just dangerous and ugly.

All in all, there’s nothing to get the heart racing. It’s a long, flat, and often windy stretch. The breaks are inconsistent, and the forecasts can change, but right now, we’re in a dry spell. Hang tight, or find a different hobby for a while.

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.
