The Lowdown
Alright, let’s get into it. It’s gonna be a slow couple of weeks, no two ways about it. For the first stretch, through the 9th of August, we’re looking at waves that are barely pushing 2 to 2 feet. There’s surf, but it’s pretty lackluster. The wind is mostly light and cross-off from the east, so the surface is clean, but there’s no power behind it. The energy in the water is weak, with numbers in the low hundreds. It’s surfable, but you’re gonna be scratching for anything. Water temp is 80°, which is about par for the course.
The first real sign of life comes on Monday the 10th. The swell picks up a touch to around 2 feet, and the energy starts to climb. Still small, but the conditions look good with light winds. It’s a start.
Now, the day you’ve been waiting for: Wednesday the 12th of August. That’s the standout. The swell pushes to 3 feet with a long 18-second period coming from the south. This is a proper groundswell. The combined energy hits 831, which is the biggest number we see in this whole forecast. The morning is looking clear with light east winds, so it should be glassy. This is the pick of the period, no question. The south direction isn't perfect for Big Beach (Big Beach), which prefers WSW, but the power behind this one will make up for it. It’s not huge, but it’s the best quality we’re going to get.
From the 13th to the 15th, the swell hangs around 3 to 4 feet, but the east wind kicks up. It stays cross-off and clean, but the energy drops and the period shortens. It gets more marginal, more of a grind. The magic from the 12th is gone.
After the 16th, it just fades. Swell drops back to 2 to 2 feet, and the conditions turn poor. A few days around the 18th and 19th are just messy and weak. A real letdown.
So, here’s the bottom line: the first week is a waiting game. The standout day is Wednesday the 12th of August. Get on it for the morning. It won’t be big, but it’ll be the cleanest and most powerful of the period. And watch out for the crowds at Big Beach (Big Beach), they can show up.
It’s a lean spell, but that one Wednesday looks worth 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.
