Aldinga Beach Surf Forecast and Surf Report

G’day, Rusty here. Look, I’m gonna level with you – South Australia’s Aldinga Beach is in a proper flat spell right now and it’s going to stay that way for quite a while. This is one of those stretches where you’re better off sorting your gear, checking the forecasts, and hoping for a change. We’ve got more than a week of near-nothing before the ocean even starts to wake up.

Right now, from Saturday 4 July through to the middle of the following week, it’s tiny. We’re talking about swell heights of 0.3ft to 1.0ft from the west or southwest, with periods around 8 to 10 seconds. The combined swell energy is barely registering – values like 12, 3, 1, 2, 3, 10, 9 – all well under 100, so weak energy. Winds are often light, sometimes glassy or offshore, which would normally be a dream, but with no swell to work with, it’s just a pretty-looking ocean. Tuesday 7 July even shows zero swell all day. There’s nothing to ride, plain and simple.

Then we hit a bit of a bump. Saturday 11 July morning sees a jump to 5ft from the west-northwest, but the period is only 6 seconds – short period windswell. Combined energy climbs to 133 (moderate), but the forecast still calls it poor surf conditions. Wind is a fresh 22 mph from the north, cross-offshore, so it’s clean, but that swell is raw and short. Saturday afternoon, it’s 5ft with 5-second period and 25 mph north-northwest winds – still clean, but rough and lumpy. Kite surfers might find this more interesting than us paddle guys, especially with that strong breeze. Sunday 12 July gets messy: 5ft from the west-southwest, 6-second period, 19-22 mph west-northwest cross-onshore wind, energy hits 159-180, but it’s fresh and choppy. Monday 13 July morning pushes 6ft from the west-southwest, 6-second period, and onshore 19 mph wind – combined energy 237 (strong), but it’s onshore slop. The swell is over 5ft, so beginners should sit this out. By afternoon it drops to 3ft with 5-second period, energy back to 77. Not worth paddling out.

After that, from Tuesday 14 July through to Saturday 18 July, it goes tiny again – 0.3ft to 1.0ft, periods 8-13 seconds, combined energy 1-13. Winds are light, sometimes glassy or offshore, but there’s no power. A few clean-looking mornings, but no waves.

Finally, Sunday 19 July shows another pulse: 6ft from the north-northwest, 5-second period, 22 mph north cross-offshore wind, combined energy 182 (strong). This is the best looking day in the whole outlook. The wind is clean, but that period is super short – the waves will be crumbly and wind-driven. Beginners stay clear; it’s too big and raw for you. Sunday afternoon drops to 3ft with 6-second period, energy 76. Still not great.

Aldinga Beach is an inconsistent beginner break, often crowded, exposed to swell from the southwest. The southern exposure means a west-northwest swell might not wrap in cleanly. There’s no standout quality day here – I can’t point to one session and say “this is it.” Water temp is 59°, about normal for this time of year, but we’re not swimming anyway with this surf.

Honestly, this is a blank run for the area. It’s going to be a long wait, but the north wind pulses on 11-13 July and 19 July offer the only glimmers – just don’t expect magic.
