The Lowdown
G'day, Rusty here. Look, I’ll level with you – it’s a tough stretch ahead for Aldinga Beach. We’re looking at a long, quiet run with hardly anything worth paddling out for. The wave energy is just flat for most of the next week or more.
Starting right now, Monday the 14th, it’s tiny. We’ve got a 1ft swell from the WSW with a short, weak period of 5 seconds and combined wave energy sitting at a paltry 13. That’s barely a ripple. The wind is onshore from the WSW at 9 mph, so it’s messy and poor. The afternoon drops even smaller to 0.7ft. This pattern of weak, small surf and onshore or cross-onshore wind sticks around day after day. Tuesday the 15th bumps up slightly to 3ft from the SW, but it’s still short period at 5 seconds, energy is only 29, and that southerly wind is 16 mph and cross-onshore, creating chop. Not a chance.
Wednesday the 16th and Thursday the 17th are the same story – tiny 0.3ft to 0.7ft waves with no power. The winds finally go light and offshore or cross-offshore on Thursday morning from the NE at 6 mph, but there’s nothing to ride. Friday the 18th, Saturday the 19th, and Sunday the 20th are all hopelessly small, with energy readings as low as 1 or 2. The water temperature is about average for this time of year, sitting at 59°F, feeling normal.
There is a brief pulse of energy on Sunday the 20th afternoon – a 5ft swell from the W with a combined energy of 120 (moderate energy). But the period is a very weak 6 seconds and the wind is onshore from the W at 9 mph, so it’s going to be lumpy and poor quality. Still wouldn’t bother.
Monday the 21st morning and afternoon are teasing us – glassy conditions with no wind, and a 1.0ft to 1ft WSW swell with a period of 10 seconds. The water will look like a mirror, but the swell is just too tiny to push any proper waves. The energy is only 41 and 33. It’s clean, but flat.
Another modest bump shows up on Sunday the 27th afternoon, with 4ft from the NNW and an energy reading of 66, but the period is short at 5 seconds. The wind is cross-offshore from the SE at 16 mph, so it’ll be clean, but the swell is weak and windswell. The only session that even gets close to being interesting is Monday morning the 28th. We get a 6ft swell from the W, energy hits a strong 205, and the wind is cross-offshore from the ESE at 19 mph – so clean conditions. The period is only 6 seconds though, so it’s a short-period, chunky windswell. At 6ft, it’s pushing the limit for beginners, but for an experienced surfer, it might offer some fun, punchy waves if the banks are okay. The afternoon drops back to 4ft and energy 94. That Monday morning is the absolute best on offer in this whole 16-day window, and it’s still not a standout.
Overall, it’s a painfully flat forecast for Aldinga Beach. There are long gaps of days with zero recommendation. If you have a kite, the afternoon of the 20th and the morning of the 28th might offer some stronger wind and swell, but for a surfboard, this is a time to focus on other things. Forecasts can change, but right now, it’s a quiet period.

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.
