The Lowdown
Alright, grab a coffee and listen up. I’m not gonna sugar-coat it for you. This stretch of the 16-day window is a bit of a flat spell for Aldinga Beach. The next week or so is looking pretty sad, with hardly any push to get excited about.
We’re looking at a real long gap here. The first few days, from Wednesday the 15th through to the start of the following week, it’s barely a ripple. The swell is tiny, mostly under 1 foot, and the wave energy is weak (12 or less). The water temp is about 58°, which is a touch cooler than usual for this time of year, but nothing crazy. The wind will be light and glassy at times, but with no size, it doesn’t matter. Honestly, it’s more of a lake paddle than a surf.
We slowly start to see a little bump around Thursday the 23rd of July. A small pulse of 2 feet swell from the west shows up, but with a short, choppy period of 5 seconds and a moderate cross-onshore wind, it’s going to be a mess. Not worth your time.
The real standout, if you can call it that, is going to be Saturday the 25th of July. The morning looks best: glassy conditions with a 2 feet swell from the SW. The wind is dead calm. The wave energy is still weak (15), but it’ll be the cleanest you’ll see all week. The optimum swell direction for Aldinga Beach is SW, so this is a good match. It’s a beginner spot and it’s inconsistent, so the crowds are often there, but with this tiny size, it won’t be packed. It’s a small-wave day for a longboard or a foamie. Later in the afternoon, the wind swings onshore and the quality drops.
The rest of the month doesn’t offer much else. A few small pulses with glassy mornings here and there, but nothing with any real oomph. It’s a quiet period for the area.

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.
