The Lowdown
Alright, Rusty here, checkin’ in on Big Beach for the next couple weeks.
Right off the bat, this break is super consistent, so we got waves almost every day. But the start is a bit rough. Tuesday the 8th kicks off with a solid 7 ft swell from the WSW, and there’s some serious power with combined energy at 2040. The problem is the S wind at 15 mph is cross-on, making it choppy and ugly. That’s more of a kite session than a paddle session. By afternoon it drops to 3 ft, but the wind stays cross-on, so it’s still marginal.
Wednesday the 9th morning is tiny, just 3 ft, with a light cross-shore wind. Not much to write home about, but by the afternoon the wind turns cross-off from the E at 9 mph, and that 3 ft SSW swell with a 13-second period starts cleaning up. Thursday the 10th is even better. The morning is clean at 2 ft with light cross-off wind, and the afternoon brings a glassy offshore breeze from the ENE at 12 mph. That 2 ft SW swell has a long 18-second period—proper groundswell—but it’s small. For a beach break, long-period swells can be a little straight, but there’ll be some fun ones.
Here’s the standout: Wednesday the 16th. Morning has 3 ft of clean SW swell with an 18-second period and light cross-off wind. Then the afternoon goes glassy—dead calm—with 3 ft of flawless, glassy surf. That’s the day. Saturday the 19th morning is also glassy, with 3 ft of clean SSW swell. Those two sessions are pure gold for a longboard or a fun log.
After that, the second week mellow out. Consistent small waves, mostly 2 ft to 3 ft, with light cross-off winds. Nothing big, nothing gnarly, but plenty of clean little waves to keep you smiling. Water temps are about average for this time of year, so no surprises there.
Big Beach sees crowds sometimes, so on those glassy mornings, don’t be surprised if there’s a few locals already in the water. Beginners will be fine with these sizes; experts might want bigger, but the quality will be there.
Best bets: Wednesday the 16th afternoon and Saturday the 19th morning.
Rusty, out.

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.
