The Lowdown
Alright, Rusty here. Let's have a look at what we've got for the local area over the next couple of weeks. I'm going to be straight with you – it's a lean stretch.
First off, we're looking at Aldinga Beach. The water temp is sitting around 58°, which is about average for this time of year, nothing to write home about.
The problem is, there's just no surf to speak of. For the entire 16-day window, the swell is tiny, mostly hovering around 0.3 ft to 1 ft. The wave energy is weak, with values like (25) and (17) – barely a ripple. The wind is all over the place, and while we get a few moments of glassy or clean conditions, like on Tuesday the 8th morning with that glassy WNW wind, there's no wave to push you around. It's all "poor surf conditions."
We've got a long stretch of nothing. From now until around Saturday the 20th, the best we see is a brief pulse of 3 ft to 3 ft on Monday the 14th and Tuesday the 15th, but with onshore and cross-onshore winds, it's not going to be any good. The swell period is short, around 4 to 5 seconds, so no power behind it. On the 19th, we see a 4 ft swell from the W, but that's coming with a 15 mph onshore wind, making it a messy, choppy mess – honestly, that setup looks more interesting for kite surfing than paddle surfing.
A few days later, around Sunday the 21st, we get a little 1 ft swell with a clean cross-offshore wind, but it's still tiny. The bottom line: there are no standouts, no days to get excited about. This is a blank run. For this area, it’s not uncommon to have these quiet spells. The swell direction is from the SW, which is the optimum for Aldinga, but without any size or energy, it doesn't matter.
Just keep the board in the car and the wetsuit dry. Forecasts can change, but right now, there’s nothing to chase.

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.
