The Lowdown
Alright, this is Rusty. Let's have a good look at what's on the cards for Big Beach over the next couple of weeks.
First off, the water temp at Big Beach is sitting at a warm 81°, which is pretty much average for this time of year, so nothing weird going on there.
Now, we’ve got a bit of a wait for the peak of this run, but the call is pretty clear: things start to build through the end of the week. We’ve got some small but clean surf on offer from Wednesday afternoon, with the swell coming from the SSW at 2ft, a very long period of 17 seconds, and solid offshore winds. The combined energy is going to be moderate at (551). That long period groundswell will be the main source of energy for the coming days, and with the wind looking favourable, the shape should be decent.
The best part of this run looks to be the following Monday morning, along with Tuesday morning. The real standout, though, is Monday the 7th of September. We’ve got a glassy clean 3ft SSW swell with a 16-second period, and the energy is cranking up to a strong (706). The wind is glassy and the conditions are flagged as very good. That’s the session you want to be in the water for. It’s a bit of a longer-period groundswell, which can make for a bit more of a wait between sets, but the quality should be well worth it. For the experienced crew, this is the one.
On the 1st and 2nd, the swell sits around 3ft to 3ft from the SSW with periods of 16 to 18 seconds, and light breezes. The energy is moderate to high (472-504). It’s a solid run of clean, fun-sized surf. Keep an eye on Wednesday the 6th as well, with the swell building back up from the SSW.
Later on, the pattern holds, with clean conditions and S to SSW swell, but the sizes drop a bit. The glassy Thursday afternoon on the 10th looks noteworthy, with a 2ft SW swell and a very long 21-second period—the energy is still moderate at (446), so expect tidy lines on the sets.
Now, a heads-up: from the start of September, the swell direction is mostly SSW, which is just about what Big Beach needs. The crowds? It’s listed as “sometimes” busy, so don’t expect too many people out there, especially on the weekday mornings.
Overall, it’s not a massive swell event, but for consistent, clean, and manageable waves with great wind, this run is a gem. The 7th of September is your true standout.

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.
