The Lowdown
Alright, Rusty here. Let’s be straight with you: the next 16 days at Aldinga Beach are looking pretty flat. There’s nothing that even sniffs a good wave – every single surf condition is rated as poor. If you’re looking to paddle out, you’re looking at a long, empty stretch. The first real chance of anything surfable isn’t until Wednesday, July 22nd, but even then it’s just a weak 3 ft swell with a short period of 4 seconds and a cross-chop, wind from the NW at 15 mph. That’s messy and tiny. Not worth the wetsuit.
The forecast basically stays flat as a pancake through the whole 16-day window. The biggest swell we see is on Thursday, July 23rd – 4 ft from the SW, but it’s only 5 seconds period and onshore wind from the SSW at 18 mph. The combined energy is just 73 – weak, and the wave comment says “poor surf conditions.” That’s for experts only if they’re desperate, but honestly, it’s more of a wind-chop session than anything else.
For the rest of the period, swell heights are mostly between 0.3 ft and 2 ft. Water temperature is about average for this time of year, so no surprise there. The wind does go glassy on a few mornings – like Friday, July 24th and Monday, July 27th – but with no swell behind it, you’re just looking at a mirror-flat ocean. Good for a paddle, not for a surf.
There are no standout days. No point breaks, reefs, or river mouths to save the day. This is a beach break, inconsistent, and rarely breaks anyway. With such weak energy and short-period swells, it’s not even interesting for kite surfing. It’s just a blank run. That’s pretty normal for this area when the swell window is quiet.
So, bottom line: leave the board at home. Forecasts can change, but right now, there’s nothing to get excited about for at least two weeks.
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.
