The Lowdown

Alright, Rusty here. Let's have a look at what's on the table for Aldinga Beach.

Honestly, it's a pretty grim run for the next couple of weeks. There's a massive gap with no real surf to speak of from now until the tail end of the forecast. The first flicker of anything surfable doesn't show up until Tuesday the 25th of August, and even then, it's nothing to write home about. You're looking at over a week of flat, small, or just plain messy conditions before we get a sniff of a wave.

The water's sitting at 57.4°F which is just about normal for this time of year, so no surprises there.

The only time the swell shows any real energy is on Friday the 21st of August, but it's a total mess. We get a spike of 8ft swell from the WSW with a short period of 7 seconds, and a combined energy of 563 (moderate wave energy). Sounds big, but it's coming straight in with a strong 12 mph cross-onshore wind from the NW. This is a chop fest, and frankly, for a beach break like this, it's looking more interesting for the kite crew than us paddle surfers. It's a proper write-off.

Then on Sunday the 23rd of August, we get another pulse, 7.5ft from the WSW and 7 seconds, with a combined energy of 550 (moderate wave energy). Same story – strong onshore wind from the SW at 12 mph. That's a washing machine, not a surf break. Only for the absolute experts, and even then, it's a battle.

The only real standout, and I use the term loosely, is on Tuesday the 25th of August. It's not big, with a head-high sort of 4.6ft swell from the West, but the real hero is the wind. It goes glassy or light offshore from the NE. That's a huge plus and will make for clean, shapey waves. The combined energy is 109 (moderate wave energy). It's a small window, but it's the best we've got. It's an inconsistent spot, so don't expect a party wave every set, but if you're keen for a paddle, this is your moment.

So, there you have it. A lot of waiting for one okay morning. That's the way it goes sometimes.

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.
