Alright, Rusty here. Let's have a look at what's on the cards for our local stretch.
To be honest, mate, the next 16 days are a bit of a write-off. We're looking at a long, dry spell with barely a ripple. The first real chance of anything rideable doesn't pop up until Monday the 20th of July, but even then, it's a short-lived pulse.
Right now, and for the next week, it's flat. There's just no energy coming in. The water temp is sitting at about 58°, which is pretty normal for this time of year, so nothing unusual there.
The only blip on the radar is at Aldinga Beach. We've got a small push of swell coming through on the morning of Monday the 20th. It's a 4ft swell from the WSW, but it's short-period stuff at 6 seconds, so it's going to be pretty weak and messy. The combined energy is only moderate (128), and with a cross-shore wind, it's not going to be anything to write home about. It's a beach break that's inconsistent and fairly exposed, but the crowds are often there.
Honestly, for the rest of the period, it's just clean, glassy mornings with zero swell. It's a tough run for the area, but these blank spells do happen. The only thing that might be worth a look is if the wind picks up, but for paddle surfing, there's just nothing on offer. The setup looks more interesting for a kite session than a surf.
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.
