The Lowdown

Alright, let’s break it down. I’m looking at the whole 16-day window for Aldinga Beach, and I gotta tell you—it’s a quiet stretch. The first real surf worth mentioning doesn’t show up until early September, and even then, it’s a slow build. There’s a big gap of nothing much from the start, with tiny dribbles and glassy days that are more for a paddle than a proper surf.

Thursday the 27th of August through the rest of the month is basically flat. Tiny 0.2ft to 0.3ft swells, mostly from the WSW or SW, with periods all over the place. You get a bit of glassy conditions on the 28th morning and afternoon, which is pretty as a picture, but there’s no wave to ride. The water temp is sitting at 58°, which is about normal for this time of year—nothing weird there.

We roll into early September, and it’s still small. Tuesday the 1st morning has a 0.3ft swell with a 15-second period—long period energy, but it’s just not enough size to do anything on a beach break. The wind is a stiff cross-off from the north at 18 mph, so it’s clean but empty.

Then we start to see a pulse. Wednesday the 2nd afternoon brings a 3ft swell from the west, period short at 5 seconds, and a cross-on wind at 15 mph. The combined energy is weak (48), so it’s a messy, choppy affair. Not really surfable with joy.

The real uptick comes on Friday the 4th of September. The morning shows a 5ft swell from the west, period still short at 6 seconds, and combined energy climbing to 127 (moderate). The wind is cross-on from the NW at 18 mph, so it’s a bit lumpy. By the afternoon, the swell hits 6ft, energy jumps to 210 (moderate), wind still cross-on. That’s getting into doable size, but the chop and short period make it a bit of a battle. Not a standout for clean surfing.

The best of the bunch, and the only real standout, is on Tuesday the 8th of September. The morning delivers a 7ft swell from the WSW, period at 7 seconds, and the combined energy is a solid 480 (strong). That’s a decent push of water. The wind is cross from the south at 9 mph, so it’s not too messy. That’s a wave for experienced surfers—over 8ft is for experts only, but this is just under that. The afternoon drops to 6ft with a clean cross-off from the SSE at 12 mph, energy at 216 (moderate). That’s a much cleaner window in the afternoon, with the wind holding off the face. If you’re out there, Tuesday afternoon is your best bet. The swell direction is WSW, which is slightly off the optimum SW for Aldinga, but it’s still workable.

After that, the swell backs off into tiny stuff again by the 9th and 10th, with glassy conditions but no power. The 16-day window fades out with 0.3ft dribble.

So, to be honest, there’s not a lot of fire here. If you’re desperate, pencil in Tuesday the 8th of September, especially the afternoon for cleaner conditions. Otherwise, it’s a waiting game. The break is inconsistent anyway, so a blank run like this is pretty normal for the area. Keep an eye on it—forecasts can change, and it tends not to stay this poor for long.

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.

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.
