The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Well, honestly, it's a bit of a flat spell for us. The first week and a half is looking pretty grim, with barely a ripple to get excited about. We're looking at a long stretch of almost nothing, especially from Friday July 31st through to Tuesday August 11th. The swell is tiny, mostly under 1 foot, and the wave energy is in the single digits (1 to 17). There are a few bigger pulses later on, but the wind is all wrong, blowing onshore or cross-onshore and making a mess of things. The only real standout comes right at the end of the forecast period, but it's a long way off.
The best bet in the whole window is Aldinga Beach on Saturday, August 15th in the morning. We're looking at a clean 7-foot swell from the NNW, with a period of 6 seconds. That's a decent size, but the short period means it'll be a bit crumbly, and at 7 feet it's more for the experienced crew. The wind is a light cross-offshore breeze from the North at 9 mph, which will keep the surface clean. Combined wave energy hits 261, which is moderate. Just keep in mind that this spot is inconsistent and often gets crowded, so you might have some company. The water temp is around 57°, which is about average for this time of year.
Earlier in the week, there's a bump on Monday, August 10th with a 10-foot swell from the West, but the wind is a howling 22 mph onshore from the WSW. That's a raw, windy mess and the wave quality is poor. It's more of a kite-surfing day than a paddle session. The energy is strong (955), but the conditions are just not there for a good surf.
So, the long story short: there's a blank period for the first ten days, then a couple of windy, lumpy days, and finally a clean, punchy but short-period swell at the very end on the 15th. It's a long way out, so keep an eye on it, but that's the only real window of hope.
Rusty.

A general guide to surfing at Aldinga Beach can be found by selecting the local surf guide option on the grey menu.

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.
