The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Big Beach over the next couple of weeks.
Straight up, I gotta be honest with you – the next few days are a bit of a slow burn. We’ve got a solid run of clean conditions thanks to a persistent east-northeasterly airflow, but the wave heights are just not there yet. The first real pulse of energy we see kicks off on Saturday the 5th, with a 5ft SSW swell but it’s got a marginal feel to it. The combined energy is moderate at 678, and while the water is a warm 81°, that’s bang on average for this time of year. It’s not a total write-off, but it’s not getting my heart racing.
Sunday the 6th is a little smaller, that 4ft to 5ft SSW swell, with that same cross-off breeze. The vibe is clean but small. The real tease comes on Monday the 7th. The morning bump is 6ft from the SW, and by the afternoon it jumps to 7ft with a 15-second period. That’s a proper groundswell, and the energy is pumping at 2622. The wind is still cross-off from the ESE at 15 mph. This is the standout of the whole window. The size is getting into that zone where it’s more for the experienced crew, but the quality is there. The swell direction is a bit south-west, which isn’t the absolute optimum for Big Beach (WSW is the sweet spot), but when it’s that size and that clean, you don’t turn your nose up. It’s the best on offer.
Things get a bit messy on Tuesday the 8th. The wind swings south, turning cross-on, and the wave quality drops off. The 8ft swell is still there in the morning, but it’s chopped up, and the energy is still strong at 1819. The afternoon drops to 5ft. It’s not the day for a traditional paddle session – this kind of setup looks more interesting for a kite surfer.
From Wednesday the 9th right through to the end of the second week, the surf fades into a long, drawn-out lull. We’re looking at waist-high dribble, mostly 1ft to 3ft for many days. The wind stays light and often cross-off or glassy, so it’s pretty as a picture, but there’s just no push. There is a tiny uptick around the 15th and 16th with small 2ft to 3ft SW swell, but it’s only enough for a longboard if you’re desperate. The confidence is high on the conditions, but low on the swell.
If you’re hanging out for something, keep your eyes on the 18th and 19th of September. The forecast is showing a late pulse of 4ft SSW swell with a 17-second period, which is a very long period groundswell. The combined energy is back up to 688, and the wind is light. It’s a long way out, so don’t book your trip off it yet, but it’s a promising hint that the dry spell might break. The crowds at Big Beach are sometimes a factor, so keep that in mind.
So, for the committed: make the most of Monday the 7th. For the rest, it’s 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.
