The Lowdown
Alright, folks, Rusty here. Let’s break down the surf for the next couple weeks.
First up, it’s gonna be a slow start. The first few days of September are a total dud. We’ve got some waist-high swell from the south, and the water’s at a normal 81°, but the wind is a mess. That steady east wind is blowing right across the face, making everything lumpy. The energy is in the moderate range (around 420-480), but the surf quality is just poor. Don’t bother paddling out yet.
Things finally start to look up on Saturday the 5th. The morning’s still a bit sketchy, but by the afternoon the wind goes offshore from the ENE. The swell hits 5 ft from the SSW, and the energy climbs to 598. That’s a solid chest-high wave with clean, offshore conditions. This is the first real highlight. Then Sunday the 6th takes it up a notch. We’re looking at 6 ft out of the SSW, with energy hitting 815. A light breeze keeps it glassy in the morning. This is prime time.
The momentum continues into Monday the 7th. Swell is 5 ft to 6 ft from the SW, and the energy jumps to a strong 1623. This is proper groundswell with a 13-14 second period, so the waves will have good shape and power. But be warned: this break is very consistent and fairly exposed. The energy is serious, and the crowds are sometimes an issue. This is for experienced surfers only.
Tuesday the 8th is a monster. Swell hits 13 ft from the SW, and the energy is a ridiculous 10754. That is a massive wall of water. But—and it’s a big but—the wind is onshore from the S, ruining the surface. Conditions are “poor” and “lumpy.” This is not a paddle surf day. If you’re into kite surfing, this setup is going to be a dream. For the rest of us, give it a miss.
After that, the surf drops off a cliff. From Wednesday the 9th right through to the end of the forecast, it’s small and weak. Waist-high at best, with energy averaging around 100-200. The wind does clean up, often going glassy or offshore, so the surface will be pretty, but there’s zero power in the waves. It’s a long stretch of ordinary, small conditions.
Looking into the second week, the 15th and 16th of September show a little pulse. Energy climbs back to 374-635 from the SSW, and the swell bumps to about 3 ft. Wind is light and cross-offshore. It’s not big, but it’s a promising sign after all that flatness.
So, the standout session is Sunday morning, September 6th. It’s got the best combo of size (6 ft), clean wind, and building energy. Monday the 7th is the big-wave day for experts, but you’ll have to handle the power and the possible crowd. The rest of the window is a waiting game.
Rusty.

Information about the Big Beach Surf forecast
The above surf forecast table for Big Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Big Beach can be found by selecting the local surf guide option on the grey menu. Our Big 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 (Big 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 Big 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.
