The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Honestly, it’s a bit of a flat spell for the most part. We’re looking at a long stretch of tiny, weak surf with only a brief pulse of size later on that might get the heart rate up for a minute. The first solid recommendation doesn't come around until Sunday the 26th of July, and even then, it’s a bit of a messy one.
For the first ten days, from Thursday the 16th right through to Saturday the 25th, it’s all knee-to-waist high dribble at best. The swell heights are barely registering, mostly around 0.3ft to 0.7ft, with the combined energy sitting in the weak range (under 100). The winds are light and often offshore or glassy, which would be great if there was any surf to ride, but there just isn't. Think of it as a good time for a paddle or a snorkel, not a surf.
Now, things get a little more interesting on Sunday the 26th of July. The morning is still small, but by the afternoon a new swell shows up. We’re looking at a 5ft swell from the northwest, but the period is a short 6 seconds, so it'll be a bit lumpy and disorganised. The combined energy jumps to 134 (moderate), and with a clean cross-offshore wind from the north, it’s surfable, but only just. The report says "very ordinary conditions," and I’d agree. It’s not a standout, just a sign of life.
Monday the 27th of July is the biggest day of the forecast, but it’s a tough one. The swell builds to 6ft from the west, but the period is still that short, weak 6 seconds. The combined energy hits 185 (moderate). The wind is a moderate breeze from the north, so it’s clean, but that’s a lot of short-period, wind-affected energy for a beach break like Aldinga Beach. For most punters, 6ft with a short period is going to be a bit of a washing machine – definitely for the experts only. The afternoon sees the wind pick up to a fresh 19 mph from the north, creating lumpy cross-chop, which makes it pretty unattractive. Honestly, with that setup, this might be more of a kite-surfing session than a paddle surf one.
The last few days of the month and into the 31st of July see the swell drop back down again, with the wind shifting onshore or cross-onshore, so the quality fades fast.
So, what’s the best on offer? There’s no real standout classic day here. The most promising session is the afternoon of Sunday the 26th of July. It’s the first day with any real energy, and the wind is clean. It won’t be perfect, but it’s the only window where you’re likely to get a few fun, albeit lumpy, waves. The water temp is around 58°, which is about normal for the time of year, so bring a decent wetsuit.
Keep your eyes on the forecasts, but for now, it’s a waiting game.
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.
