Table - best surf conditions forecast for Aldinga Beach over the next 16 days.
Alright, Rusty here. Let's talk about what's happening at Aldinga Beach over the next couple of weeks.
Honestly, it's a pretty grim stretch ahead. For the next week and a half, there's almost nothing worth paddling out for. The first real glimpse of anything rideable doesn't show up until July 24th, and even that's a "surfable but very ordinary" situation. You're looking at a solid 11-day gap where the swell is either tiny, onshore, or both. The combined swell energy is non-existent, reading at just 65 to 1 on most days – barely a ripple.
The water temperature is about average for the time of year, so no shock there.
Now, the only faint glimmer in this entire 16-day window is Saturday, July 25th. That morning, we get a pulse of 7.2ft swell from the west, with a clean, offshore wind. The combined energy jumps right up to 380 (moderate), and the forecast actually says "expect good surf conditions." The tide and break setup will be key because that's a fair bit of size for this beach – it'll be too big for beginners, and the short, 6-second period won't do it any favors for shape. It'll be a lumpy, powerful closeout for most, but for the experienced crew who can handle a clean, solid west swell, it could be the only session of the month.
After that, it drops back into mediocrity. The 26th sees more size but with strong onshore winds, ruining it. The 27th and 28th are just messy again. Don't hold your breath for the rest; it's a write-off.
So, there's one morning to circle: Saturday, July 25th. Get it if you can, because the rest of this outlook is as dry as a sand dune.

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.
