The Lowdown
Alright, Rusty here. I'm not gonna sugarcoat it: the next 16 days at Aldinga Beach are looking grim. There's a long, flat spell ahead with next to nothing to paddle into.
The first glimmer of something, and I use that word loosely, is on Sunday the 26th of July. The morning is a mess with onshore wind, but the afternoon cleans right up. It goes glassy, with a 3ft swell from the west. The combined energy is weak, but with the wind totally off, it's the cleanest we'll see all forecast. The period is a short 4 seconds though, so it'll be weak, lumpy little waves. For a spot that's inconsistent and geared toward beginners, this is the best on offer, and that's not saying much.
Monday the 27th is a repeat. The swell pushes up to 4ft from the WNW, with a little more energy, and light cross-shore winds. It'll be small and a bit messy, but rideable if you're keen.
After that, the tank runs dry. The wind lays down a bit on the 31st of July and the 1st of August, but the swell is gone, dropping to under 1ft. The combined energy tank is practically empty. The water temp is about what you'd expect for this time of year.
The very end of the run, on Tuesday the 4th of August, has a weird one. A 0.3ft swell with a *very long* 18-second period. That's a ground swell with no height, so it won't break. The combined energy is a weak 14. Nothing at all.
Honestly, this is a lean run. For a beginner, the Sunday afternoon or Monday morning might offer a tiny, clean crumb. For everyone else, forget it. A few of those windy, choppy days might be more fun for a kite than a surfboard. Forecasts can change, but right now, it's a waiting game.
Rusty.

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. If you surf the same spot (Aldinga 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 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.
