The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
We've got a bit of a slow roll here, nothing too hectic. The swell is hanging around the 1.5 to 3.0 ft mark, and while the direction is mostly out of the S or SSW, the wind is staying offshore or cross-off from the ENE most of the time. That’s a real win for keeping things clean. The water temp is sitting right around 80.6°, which is bang on average for this time of year, so no surprises there.
The swell periods are kicking in the 13 to 19 second range. That's proper long-period groundswell, so you’re getting good energy and nice shaped lines, but be ready for longer waits between sets. With that in mind, a beach break like Big Beach can get a bit too straight with that kind of period; the waves might just wall up and roll through a bit too fast.
Looking at the first few days, Thursday the 27th and Friday the 28th have the most consistent, clean conditions. There is not much on offer after Friday afternoon until Sunday the 6th of September, a solid week-long gap where it just goes a bit too small or the wind swings. But when that Sunday morning on the 6th rolls around, it’s looking like the standout. We get a morning with clear skies, light offshore breeze from the NE at 6 mph, and a clean 3.0 ft SSW swell. The combined energy is moderate at 449, so it’ll feel punchy enough for a longboard or a fish. The water should still be nice and warm. That's the one to circle on the calendar.
After that, through Monday and Tuesday, the ENE wind picks up again, keeping things cross-off and clean, but the swell energy stays moderate around 413 to 430. For a true standout though, stick with that Sunday morning on the 6th at Big Beach.
Alright, that's all I've got for this stretch. Keep an eye on it, because once that swell fills in, it could get real fun. Over and out.

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.
