The Lowdown
Alright, surfers, Rusty here. Let's take a good, hard look at what Big Beach has in store for us over the next couple of weeks.
Right off the bat, I gotta be straight with you – this ain't gonna be a classic stretch. We've got a long, flat run ahead. There’s absolutely nothing doing until Friday the 11th, so don't bother paddling out until then.
Things kick off Friday morning with a tiny 2ft SW groundswell. The energy is weak to moderate (252), but the real killer is the cross-off wind. It'll be clean, sure, but the waves are just ordinary. Saturday and Sunday are more of the same – small, average surf. You might get a fun little wave if you're a beginner on a foamie, but don't expect much.
Now, let's talk about the one real highlight. Monday the 14th afternoon things start to get interesting. That SW swell holds at 2ft, but the period jumps to a very long 22 seconds, and we get proper offshore winds from the NE. The energy kicks up to moderate (276) and the forecast is actually calling for *good* conditions. That very long period means the waves will have real shape and power for a beach break, with long lulls between sets making the paddle out a bit easier. For a spot this small, that's about as good as it gets. Tuesday the 15th and Wednesday the 16th mornings are also looking solid with similar 2ft – 3ft SW swells, long 20-second periods, light breezes and clean conditions. The energy is moderate to strong (434-441). If you've got a log or a fish, these will be the sessions to aim for.
The water temp is about average for this time of year, so a spring suit is all you'll need.
After that little window, it gets a bit messy. From Thursday the 17th through the weekend of the 20th, the swell stays in the 2ft to 3ft range with moderate to strong energy, but the wind shifts to a stiffer cross-off, and the conditions turn marginal. Not terrible, but not great either.
The second week is a slow fade. Monday the 21st and Tuesday the 22nd still have some waist-high swell, but the energy is dropping and the quality is ordinary. By Wednesday the 23rd, the wind goes onshore, and from Thursday the 24th all the way through Saturday the 26th, we’re looking at onshore slop. The last day, Saturday morning, goes glassy with a 2ft SSW swell, but it's just too weak to get excited about.
So, the call: The absolute standout is Monday the 14th afternoon through Wednesday the 16th morning. Get on it if you can. The rest is mostly a write-off for a proper paddle session. This setup might actually be more interesting for the kite crew than us.
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.
