The Lowdown
G'day, I'm Rusty. Look, I'm not gonna lie to you—the next couple of weeks are looking pretty flat and uninspiring around here. We've got a long stretch of nothing much on the cards, and I mean a proper dry spell. Hold onto your boards, 'cause from now until at least the 8th of August, you'll be lucky to get a ripple.
Our only real option on the map is Aldinga Beach, but don't get your hopes up. For the first week, the swell is barely a whisper. Thursday the 30th of July kicks off with a tiny 1 ft swell from the WSW, and while the morning is glassy with a light ESE breeze at 5 km/h, the wave energy is weak as water (11). The afternoon gets a cross-on wind, making it messy. Friday the 31st is the same story—0.3 ft of nothing, though we get a clean morning with a light offshore ENE wind. Saturday the 1st of August is clean again but the swell is still 0.3 ft. Sunday the 2nd sees a jump to 4 ft from the NNW, but it's wind-affected with a fresh 30 km/h cross-shore breeze, and the period is a short 5 seconds—just lumpy, choppy junk. The combined energy hits a moderate 88, but the quality is still poor. The rest of the first week is more of the same: tiny, weak, and often onshore or cross-shore.
There is a glimmer of hope on Sunday the 9th of August. The afternoon brings an 8 ft swell from the west, but the period is a short 5 seconds, and a fresh 30 km/h cross-shore wind from the NNW will turn it into a bumpy mess. The combined energy is strong at 662, but with the wind and short period, it's for experts only, and even then, it's gonna be a battle. Monday the 10th of August drops back to 5 ft with a strong onshore wind—not worth the drive.
Aldinga Beach is an inconsistent beginner's spot, so it's not built for big, powerful swells anyway. The crowds can be often, but with surf this poor, that won't be an issue. Honestly, with the predominant onshore and cross-shore winds, and the often short-period, lumpy conditions, this setup looks more interesting for kite surfing than paddle surfing over the coming days. Hang in there, folks—this flat spell is a long one, but forecasts can always change.

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.
