The Lowdown
Alright, Rusty here. Let’s get into it for Big Beach. We’ve got a bit of a slow grind ahead for the next couple of weeks, but there are a couple of windows that’ll get the blood pumping.
Right off the bat, the water’s sitting at a warm 81°, which is about normal for this time of year, so no surprises there.
The first real sniff of anything decent won’t come until the very start of next week. We’ve got a few days of small, marginal surf to start. Thursday the 27th and Friday the 28th offer up some clean waves around 2 ft to 3 ft, but the energy is weak to moderate. It’s surfable, but nothing to write home about. The crowd factor is ‘sometimes’, so you might have some company on the small stuff.
We hit a bit of a flat lull from Saturday the 29th right through to Monday the 1st of September. The swell drops to knee-high and the energy bottoms out. There’s a brief uptick on the 1st with a bit more energy, but the quality is still ordinary.
The first real standout appears on Monday the 7th of September. The afternoon session is looking sweet. A clean 3 ft swell from the SSW, with solid energy behind it and a period of 15 seconds. That’s a proper groundswell. Wind is a light breeze from the ENE, keeping it clean. This is the best on offer for the whole run – not too big, nicely shaped, and the conditions should be classy.
Hot on its heels, Tuesday the 8th of September morning is a serious contender. The swell bumps up a touch to 4 ft from the SSW, and the wind goes glassy straight from the NE. That’s as clean as it gets. This is your other highlight. The period is a long 16 seconds, which will mean proper lines but long waits between sets. For a beach break like Big Beach, that period can make the walls stand up a bit, but with glassy conditions, it’ll still be a joy.
After that, things taper off again. The surf stays clean through Wednesday the 9th, with 3 ft and offshore winds, but the energy drops off. By Thursday the 10th and Friday the 11th, we’re back to little wind slop and small swell, finishing the run with a flat, glassy day on the 11th with practically no push.
Overall, don’t bother paddling out until the 7th. That Monday afternoon and Tuesday morning window, stepping into the second week, is where the magic is. It’s still a week and a half out, so keep an eye on it, but that’s the one to circle on the calendar.
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.
