The Lowdown
Alright, Rusty here again, this time in feet and miles per hour for you.
This stretch is looking pretty lean. For the next 16 days there’s nothing that’s firing, and the first decent surf is a long way off. Right now, through the end of July and into early August, we’re looking at a whole lot of tiny, gutless waves with onshore and cross-shore wind messing up what little there is. There’s a gap of about a week and a half where you’d be better off doing something else. The combined swell energy is barely registering, often in single digits or low double digits, so it’s weak.
Looking at Aldinga Beach (South Australia), the only real window of interest is around Tuesday the 28th of July. The morning brings a bit of a pulse – 4ft swell from the NW, with a period of 5 seconds and combined energy of 90. That’s still not great, and the wind is a moderate cross-shore at 25 mph, so it’ll be a bit messy. It’s not a standout for quality, but it’s the biggest swell in the whole outlook. The water temperature is about average for the time of year.
After that, it drops right back into the tiny stuff. By Sunday the 2nd of August, there’s a glassy afternoon with 3ft swell from the west, period of 5 seconds, and energy of 29. At least it’s clean, but it’s small and weak. The rest of the first week of August is just ankle-biters with clean but tiny conditions.
Honestly, there’s not a single day I’d get excited about paddling out. The combination of small swell, short period, and less-than-ideal wind windows means the surf is barely worth a look. If you’re desperate, the 28th of July morning is the only time the swell cracks a couple feet, but it’s not pretty. For the rest of the forecast, it’s a flat spell with occasional clean but tiny waves.
Stay patient, and keep an eye on the forecasts. It tends not to stay this quiet forever.
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.
