The Lowdown
Alright, let’s be straight with you. The charts for Aldinga Beach show a real dry spell coming up. There’s a big gap of days with nothing worth paddling out for.
The first bit of data is for Thursday morning, July 16th. We’ve got a tiny 0.7ft swell from the WSW with a short 8-second period, and the combined energy is a weak 6. The wind is light and glassy from the NE, so the ocean will look smooth, but there’s zero power. This flatness is gonna hang around for a long stretch.
From July 16th all the way through the 29th, it’s nothing but poor surf conditions. Swell heights barely reach 0.7ft and often drop to 0.3ft. Even when a longer 14-second period swell shows on the 18th, it’s only 0.3ft high – that’s not surfable. Winds are sometimes clean, sometimes glassy, but it’s all irrelevant with no waves.
There’s a slight bump on July 24th, with the swell hitting 2ft, but the period plummets to a terrible 4 seconds. That’s windswell, and with a fresh cross-onshore breeze, it’s choppy and messy. The combined energy is only 12 – still very weak. This looks more fun for a kite surfer than a paddle surfer.
The end of the month still doesn’t deliver. On July 29th, we finally see a 3ft swell from the WNW, but the period is a short 5 seconds, and a fresh cross-onshore wind from the SW makes it lumpy. Combined energy is 49 (moderate), but the quality is poor. That size is too much for beginners, and with those conditions, it’s not great for anyone.
The best option in this whole 16-day window is a sorry one. If you’re keen, the morning of Sunday, July 26th offers a 2ft WSW swell with a clean offshore wind from the ENE. But the period is only 3 seconds, and combined energy is a pathetic 7. It’s barely a ripple. The afternoon on the 26th has a 2ft W swell with a 4-second period and energy of 18, but the wind goes onshore, making it messy. That’s the best we’ve got – and it’s still poor.
Don’t worry about crowds; no one is paddling out. This is a normal winter flat spell for this area. It won’t last forever, but for now, save your energy.

Information about the Aldinga Beach Surf forecast
The above surf forecast table for Aldinga Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Aldinga Beach can be found by selecting the local surf guide option on the grey menu. Our Aldinga 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.

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 Aldinga 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.
