The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for Big Beach over the next couple of weeks.
Straight up, this isn't a period of epic, hold-onto-your-board surf. The swell energy is mostly moderate, with combined energy values in the hundreds. The water temp is sitting at 80°, which is about average for this time of year, so nothing unusual there.
The first real standout appears on Tuesday morning, the 1st of September. We've got a clean 3ft swell from the SSW, and with a light offshore breeze from the NE, the conditions are looking good. The wave energy is solid, and the period is a long 18 seconds, which is proper groundswell. This long period will mean better shaped waves, but be aware it might make the break a bit straight at a beach setup. This is likely the best session on offer.
The next notable session is on Friday afternoon, the 4th of September. The swell picks up to 5ft from the S, with a moderate offshore breeze from the ENE. The combined energy is strong, and the swell period is 11 seconds. This is a solid, surfable wave, but with the size over 5ft, it might be a bit much for beginners. The earlier morning session on Friday also has 5ft swell but the conditions are described as more marginal.
After that, the surf drops off a bit. You'll see some smaller, cleaner waves on Saturday the 5th (3ft to 3ft) and Sunday the 6th (2ft to 3ft), but nothing that jumps out as a must-surf session. The consistency is there, but the quality is just ordinary.
Moving into the second week, the surf becomes smaller and less consistent. From Monday the 7th through to Tuesday the 15th, the swell height stays mostly between 1ft and 3ft, with the combined energy dropping. The wind is a bit more variable, with some cross-off and cross-on conditions. There are a few sessions with a decent score, like Tuesday morning the 15th with a 2ft SSW swell, light NE offshore, but it's not a standout. Overall, the second week looks like a bit of a flat spell.
So, if you're keen, the pick is Tuesday morning, the 1st of September, for the cleanest, most powerful waves of the forecast. The Friday afternoon session on the 4th is your next best bet for a bit more size.
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.
