The Lowdown

Alright, let me look at what we’ve got here. Honestly, mate, it’s a tough stretch. We’re staring down a 16-day window with no real surf to get excited about. The swell is tiny, barely a ripple, and the wind is all over the shop. It’s a flat spell, and for Aldinga Beach, a blank run like this isn’t that unusual. The setup is inconsistent at the best of times, and right now, there’s just nothing doing.

The whole period from now through to the 6th of September is a dud. The swell barely cracks 2 ft in the best hour, and most of the time it’s sitting at 0.3 ft or 0.7 ft. The combined swell energy is pitiful, never getting past a weak 37 (that’s a 37 on the energy scale). It’s a long, flat, frustrating wait. The water temperature is about average for the time of year, nothing weird there.

The absolute best you could say is for the 28th of August, Friday afternoon. We get a 3 ft swell from the SSW, but it’s a short-period, choppy mess with onshore winds at 15 mph. It’s poor surf, and with the wind and the short period, it’s more of a messy, blown-out situation than something you’d paddle out for. The 29th of August is similar, with a 3 ft S swell but again, onshore and lumpy. The energy is still weak, hitting 34.

There’s a couple of glassy mornings, like the 24th of August, but the swell is 0.3 ft – you’d be floating. The 4th of September has a glassy start with a 0.7 ft WSW swell, but again, it’s just not enough. For a beginner, anything over 5 ft is too much, but we’re so far under that it’s barely a puddle. For experts, there’s nothing. This is a kite surfer’s dream maybe, with the consistent wind, but for a surfer? We’re waiting.

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.
