The Lowdown

G’day, Rusty here. Lookin’ at Aldinga Beach, it’s a bleak stretch ahead. The next sixteen days are almost completely flat, with no real surf worth your time.

The first few days are a write-off. Swell heights are tiny – 0.7ft at best – and the wave energy is weak, around 21 on Friday morning. By Saturday the 22nd we get a long 14-second swell, but it’s only 0.3ft – barely a bump – and the energy drops to 20. Not worth wetting a wetsuit.

From Sunday the 23rd through the end of August, it’s the same: waves between 0.3ft and 0.7ft, periods all over the place, and mostly cross or cross-off breezes. On Tuesday the 25th, a 1.0ft swell appears with a 4-second period and a cross-shore south wind – all chop, no shape. Wednesday the 26th is no better with a 0.7ft swell and an onshore breeze.

The gap in decent surf is massive. Nothing picks up until the 4th of September – that Friday morning we see a 2ft west swell with a 5-second period, giving a combined energy of 26 (still weak). But the wind is onshore from the WSW at 19 mph, so it’s choppy and messy. Saturday the 5th is clean with a strong offshore north wind at 19 mph, but the swell is only 0.7ft – you’ll be floating, not riding.

Water temp on Friday the 21st of August is about 57°F, which is average for the time of year. Nothing unusual.

With swell never getting above 2ft and wave energy staying weak (always under 100), this is strictly for the smallest of foamies, and even then, it’s mostly flat. This break is inconsistent and rarely breaks, so a long blank run like this is standard for Aldinga. It’s fairly exposed to a SW swell, but when it’s this weak and short-period, there’s nothing to surf.

If you’re bored, maybe a kite would work on a gusty day, but for paddle surfing? Save your energy.

No standouts. The near-term is reliable – it’s gonna stay poor – and the September 4 bump is too weak to get excited about. Forecasts can change, but right now, it’s a no-go.

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.
