The Lowdown
Alright folks, Rusty here. Let's have a look at the coming swell window for our local stretch.
We've got a bit of a slow start, but there's some fun, clean surf on the horizon. The water's sitting at a warm 81°F, which is pretty much spot on for this time of year, so no need for a wetsuit.
Kicking off on Wednesday the 26th of August, we see a small SSW swell filling in at Big Beach. It's a long-period groundswell, 14 to 17 seconds, which gives it a nice push. The morning has a bit of cross-off wind, but by the afternoon the wind swings offshore and we're looking at clean 2ft waves. The combined energy is moderate at 551, so there's a bit of grunt in the water. It's a good session for a longboard or a funboard.
Thursday the 27th is the standout. The morning sees a 3ft SSW swell, with a very long period of 16 seconds and a combined energy of 957 (moderate). The wind is a gentle cross-off, keeping the surface clean. The afternoon cleans up even more with a solid offshore breeze from the NE. The swell direction is SSW, which is close to the optimum WSW for the spot, so the waves will be holding up well. This is the best of the bunch, folks. It's a very consistent break, so you'll get plenty of waves. The crowd can be "sometimes" busy, but for these conditions, it's worth sharing the line-up.
Friday the 28th keeps the fun rolling with similar 2ft waves from the S, with offshore winds in the afternoon again. Solid, consistent surf.
The weekend (29th and 30th) drops off a bit. The swell dips to 2ft to 2ft and the combined energy weakens. The wind stays offshore, but the waves are just too small to get excited about.
We get a bit of a lull through Monday and Tuesday, but then a new pulse arrives on Tuesday the 1st of September. The morning shows a 3ft SSW swell with a very long 18-second period, and a combined energy of 504 (moderate). The wind is light and cross-off, so it's clean. The next few days, up to the 4th, keep offering 2ft to 3ft waves with generally clean conditions, though the periods drop a bit into the 13-14 second range.
Around the 6th and 7th of September, we see another nice push. The swell builds back to 3ft from the SSW with a 16-second period, and the combined energy hits 477 (moderate). The morning winds are light, making for some really clean, long-period lines. This is a promising run, but it's a week and a half out, so keep an eye on it.
The second week keeps the trend of small, clean surf. The 8th and 9th of September have solid offshore winds again, with 2ft to 3ft SSW swell. The period drops to 14 seconds, so it's not as powerful, but the offshore breeze will make it fun.
Overall, the best on offer is Thursday the 27th of August. The morning and afternoon both have clean, offshore winds, a nice 3ft SSW groundswell, and moderate energy. It's a consistent, reliable spot, so get out there and enjoy it.
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.
