The Lowdown

G’day, I’m Rusty, and I’ve been staring at the charts for Aldinga Beach (South Australia) and, well, it’s a tough one. For the next 16 days, there’s no real surf to get excited about – the forecast is full of zero scores and the word “poor” keeps popping up. It’s a dry spell, and for this area, a blank run like this isn’t too unusual when the conditions don’t align.

Starting off, Friday the 7th of August delivers a tiny 0.7ft swell from the WSW with a 10-second period, but the wind is cross and it’s just messy. The combined wave energy is a weak 18 – not enough to bother paddling out. Saturday the 8th stays tiny, with 0.7ft and 0.3ft waves, and while the wind turns cross-offshore, these are kiddie-pool numbers. The water temp is sitting at 57°, which is about average for the time of year, nothing weird.

Sunday the 9th morning is still flat with 0.7ft, but the afternoon sees a bump of 5ft from the NW, period a short 5 seconds. That sends the combined energy to 140 (moderate), but the wind is a fresh cross-shore, and the forecast still calls it poor surf. Monday the 10th has a 5ft onshore mess from the WSW, energy at 170, but the wind is straight onshore – unrideable.

Things get a bit bigger mid-week, but it’s ugly. Wednesday the 12th has a 7ft W swell (6-second period) with energy at 379, and an 8ft W swell (7 seconds) with energy at 698 – that’s strong wave energy. But the wind is a strong onshore, and the break is a beach. This setup is more interesting for kite surfing than paddle surfing. For the experts, that 8ft is only for the brave, but the wind will ruin it.

From Thursday the 13th onward, it’s back to tiny 1ft, 1.0ft, 0.7ft, and 0.3ft swells for over a week straight. The combined energy drops to single digits and low double digits – weak, weak, weak. The wind does turn clean and cross-offshore on several days, and even glassy on the 18th, but there’s no swell to push the waves. The 18th has a 0.3ft SW groundswell with a 13-second period, but it’s just a ripple.

The only standout worth mentioning is a potential little bump around Thursday the 20th of August. A 4ft NW windswell (4 seconds) on the morning, energy 56, and a 4ft WSW swell (6 seconds) in the afternoon, energy 104. The wind is cross-off in the morning and cross in the afternoon, and the forecast still says poor surf. It’s inconsistent and rarely breaks here, and even this isn’t enough to get the heart pumping. Honestly, leave the board in the shed for a while. Forecasts can change, but this stretch looks like a write-off.

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.
