Table - best surf conditions forecast for Maslin Beach over the next 16 days.


G'day, Rusty here, and I’ve gotta be straight with you – we’re looking at a pretty quiet picture for Maslin Beach over the next 16 days. There’s nothing on offer that I’d be rushing to wet a line for. The surf is small and the conditions are mostly a write-off. It’s a classic winter lull for this beach and reef setup.

We kick off on Wednesday, 8th July, with tiny 0.3ft waves from the west and a long 11-second period. There’s almost no energy in the water (combined energy of just 2), so you’d be floating more than surfing. The water’s sitting at 59°F, which is about average for this time of year. The morning has a light breeze, but the afternoon goes glassy with zero wind. It’s clean, but with swell that small, it’s just not worth it.

That flat spell drags on for days. Thursday, 9th July, stays at 0.3ft with a bigger period, but still poor. The wind shifts around, but the wave height barely registers. By Friday, 10th July, we’re still stuck at 0.3ft, and a gentle cross-shore wind just chops it up.

Come Saturday, 11th July, things get weird. The morning is rainy with a strong 40 km/h cross-onshore wind, but then the afternoon throws up a sudden spike: 8ft from the west-southwest with a short, punchy 7-second period. That’s a big jump, and the combined energy hits 687 – that’s strong and powerful. But with that much onshore wind and the short period, it’s messy and lumpy. This is expert-only territory at that size, and the wind will make it a battle. Honestly, it looks more interesting for a kite surfer than a paddle surfer.

After that, the rest of the forecast is a slow, drawn-out fade. Sunday, 12th July, drops to 5ft in the morning, and then it’s all onshore winds and rain through the week. By Wednesday, 15th July, we’re back to 3ft with some clean cross-offshore wind in the afternoon, but the energy is weak (combined energy of 25). The following Thursday, 16th July, has a tiny 0.7ft wave with morning offshore wind from the east, but it’s barely a ripple.

From Friday, 17th July, through to the final Wednesday, 23rd July, it’s all 0.3ft to 2ft waves with poor wind and messy conditions. There’s a brief moment on Tuesday, 22nd July, with glassy conditions in the morning and a 3ft wave, but again, 5-second period and low energy (combined energy of 53) mean it’s just not going to give you anything worth paddling out for. The last day, Thursday, 23rd July, is glassy but only 2ft.

In short, this is a blank run for Maslin Beach. Don’t hold your breath – conditions like these are normal for the area in winter, but forecasts can change. For now, save your energy.

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.
