The Lowdown
Alright, Rusty here. Let’s break down what we’ve got on the cards for Big Beach.
We’re looking at a pretty quiet stretch overall. The water is sitting at a very average 80.4°F for this time of year, nothing unusual there. The surf is going to be small and inconsistent for most of the run. We’ve got a couple of longer-period groundswells in the mix, which will help with shape, but the size just isn’t there for anything special for a while.
The first real standout doesn’t show up until Monday the 7th of September. That Tuesday morning will see some clean, glassy conditions with light NNW offshore winds and a 3.3ft SSW swell. The period is a long 17 seconds, which means proper, lined-up waves. The combined energy hits 704 (moderate to strong). That’s the best looking window for a decent paddle. But be warned: that same swell later in the afternoon gets shredded by a cross-onshore wind, so get out early.
Before that, Tuesday the 1st of September morning might offer a little something with a 3.0ft SSW groundswell at 18 seconds and clean NE offshore winds. It’s small, but it’ll be tidy. The energy is moderate at 592. It’s a gentle option for a beginner surf.
From Wednesday the 2nd right through to Sunday the 6th, it’s mostly marginal. Small swell in the 2.0ft to 5.0ft range, but the winds are mostly cross-off or offshore. It’s rideable, but nothing to write home about. The combined energy values hover in the 200 to 500 range, telling you it’s weak to moderate. The 5.0ft on Friday the 4th morning is the biggest, but it’s short-period (11 seconds) and the conditions are only just okay.
After the Monday the 7th highlight, it drops right off. From the 8th through to the 15th, it’s almost entirely small surf under 3.0ft, with most days showing combined energy below 300 (weak). The longest gap of genuinely poor-to-ordinary surf runs from the 10th right through to the 15th. A few sessions on the 15th Tuesday look *okay* with a 2.3ft to 1.6ft SSW swell and offshore wind, but it’s really just a way to wet your board.
The Pick: Get out on Monday the 7th of September morning. That 3.3ft, 17-second SSW groundswell with light offshore NNW wind and strong-ish energy (704) is the cleanest, most promising surf in this whole 16-day window. It’s not huge, but it’ll be quality. Keep an eye on it.

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.
