The Lowdown
Alright, Rusty here. Let's talk about what Big Beach has in store for us.
The next couple of weeks are a bit of a slow burner. We're starting off with some real ankle-biters that aren't worth paddling out for. For about the first week, from Tuesday afternoon all the way through to the morning of Saturday the 9th of August, the recommendations are basically zero. It's a flat spell, with only dribbly knee-high waves and average wind. Just sit tight.
But then, things turn around. The standout window comes on Sunday the 9th of August. Big Beach finally wakes up. We've got a solid 3ft swell rolling in from the SSW, with a period of 18 seconds. That's a long-period groundswell, so expect good shape and proper power. The combined energy reading is a massive 800 (strong), and a gentle breeze will keep it clean. It's well worth the wait. This keeps up into Monday the 10th of August, with the swell pushing up to 4ft from the same SSW direction, holding a 16-second period. The combined energy is even higher at 891. Monday afternoon is the real gem, with a gentle offshore breeze (NE at 9 mph) promising glassy, clean waves. That's the pick of the whole forecast, no question. The water is sitting at 80°, which is about average for this time of year, so the boardies are fine.
After that, the swell fades, but we'll still see some fun-sized waves through to Wednesday the 12th of August, with the swell dropping back to around 3ft.
So, to keep it simple: forget the first week, and mark Sunday the 9th through Monday the 10th on your calendar. That's your window.
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.
