The Lowdown
Alright, let’s get real about Aldinga Beach. It’s a pretty bleak outlook for the next couple of weeks. Most of the time there’s just no swell to speak of—tiny, weak waves and not much energy. Looking at the first week, the swell is barely a ripple, sitting around 0.3ft to 0.7ft. The wind is often light, sometimes even glassy, but with no wave power, it’s a flat spell. The combined energy is in the single digits to low teens (weak), and the surf conditions are consistently poor. You’re looking at a long dry run from now through the end of July.
The first real pulse of swell arrives on the morning of the 30th of July. We see a 6ft SW swell with a 6-second period, and the combined energy jumps to 210 (moderate). The wind is a light cross-off from the N, so it’s clean. The surf quality is still described as “very ordinary,” but it’s the closest thing to a wave we’ll see. That morning is your best bet, but don’t expect much. The period is short, so it’ll be a bit crumbly and disorganised.
After that, the swell drops back down quickly into the first week of August, with the wind turning onshore or cross-shore and strong, making things chop up. The water temperature feels about average for this time of year.
The standout is the Thursday morning, 30th July, at Aldinga Beach. It’s the only time the swell height gets over 5ft. But honestly, the quality is poor, so it’s more of a “last resort” kind of session. Keep your expectations low.

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.
