Alright, let’s get into it. I’m not gonna lie to you, it’s been a tough run. Maslin Beach has just had nothing doin’ for days. That’s what it’s like sometimes – the ocean just shuts the door for a bit. Right now, from the start of July through the first week, we’re looking at flat to near-flat conditions. Tiny dribbles of 0.3 ft from the west, no energy to speak of – combined energy readings down at (3) or (1) – it’s all zero out of ten stuff. The wind is light and sometimes glassy, but there’s simply no swell to work with. You’d be sitting out there on a millpond. That flat spell runs all the way from Sunday the 5th through to Friday the 10th of July – a proper dead period.

Come Saturday the 11th, we finally see a pulse, but it’s ugly. A north wind kicks up to 16–22 mph, cross-shore and lumpy, with a short-period 2 ft to 3 ft bump – combined energy (23) to (33). This isn’t surfable. Sunday the 12th gets worse: rain showers and a fresh cross-onshore blow dragging up a 5 ft mess of windswell (143). That’s kiter territory, not paddle surfing.

Then, Monday the 13th is where it gets interesting for the real crew. A clean south-southeast offshore breeze hits, and we see a 6 ft swell from the west-southwest at a period of 6 seconds. Combined energy jumps to (263) – moderate, but with real push. That morning will hold the cleanest shape, but it’s already pushing the limit for beginners at nearly 7 ft. By afternoon, the wind goes cross and the swell pushes to 7 ft (420)… that’s expert-only territory, and lumpy with it. If you are a good surfer, the Monday morning session on the 13th is the standout of this whole outlook. The break is a beach and reef, so that clean offshore makes it worth the trip. Water temp is sitting at 59°, which is about normal for this time of year – nothing wild.

Tuesday the 14th still has size – 7 ft in the morning (356) – but the wind is cross, so it’s a bit messier. Still plenty of energy for a strong paddle. After that, it fades fast. Wednesday and Thursday drop below 3 ft again, and we’re back to poor surf and weak little dribbles through the rest of the second week. Friday the 17th sees another onshore spike – 4 ft from the north-northwest (80) but choppy and ugly. Saturday the 18th brings a slight improvement: 5 ft from the west (141) with a light cross-shore, but nothing special.

By Sunday the 19th and Monday the 20th, we get a last gasp of clean conditions – a glassy 3 ft on Sunday morning with an easterly offshore, and a glassy 1.0 ft on Monday, but both are small. Sunday the 19th morning might give you a fun little session if you’re desperate, but it’s no size.

Overall, if you’re after the one real highlight for Maslin Beach in this 16-day window, it’s Monday the 13th of July – clean offshore, close to head-high, and the best energy of the whole run. Get in early before the wind swings.

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.
