The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Big Beach.
Right off the bat, we’ve got a bit of a slow start. The first real surf worth paddling out for shows up on Thursday afternoon, July 16th. We’re looking at clean 2ft surf from the SSW with a solid 13-second period. The wind is a cross-off from the ESE at 9 mph, so the surface should be tidy. The water’s sitting at a warm 80°, which is pretty much average for this time of year. The combined energy is moderate at 453, and it’s a classic beginner-friendly break that’s very consistent. It’s a good, gentle intro to the run.
Things get a bit ordinary over the weekend. Friday and Saturday are mostly cross-off breezes and small, weak swell. The period on Sunday morning jumps to 19 seconds, but it’s only 1ft, so you’ll be waiting a long time between sets. The energy is low (192). Not really worth getting wet for unless you’re desperate for a paddle.
Now, Monday July 20th is where it starts to turn. Morning glass-off with 3ft swell from the south, 16-second period, and the energy bumps up to 505. That’s a proper moderate groundswell, and with light winds, it’ll be clean. Monday afternoon holds with offshore NE wind at 6 mph. This is a solid, reliable option.
Tuesday July 21st keeps the run going with 3ft south swell, but the wind goes cross-off again. Still clean, still surfable.
The real standout window opens up on Wednesday July 22nd afternoon. We’ve got offshore wind from the ENE at 16 mph, a 2ft SSW swell, but check the period: 23 seconds! That’s very long-period groundswell. The energy is a strong 632. This is a proper reef or point break kind of swell – it’ll offer up long, lined-up waves. That offshore wind will make it look like a postcard. Keep in mind, for a beach break, that long period can make the waves a bit too straight, but the conditions are so good it’s hard to complain.
Then Thursday July 23rd morning is the best of the bunch. Still 3ft from the SSW, 20-second period, and the energy is pumping at 719. The wind is a gentle cross-off from the east. The forecast confidence is high for this one. It’s the pick of the whole run for a clean, fun session.
The following week, from July 25th onwards, we see a bit more size. Saturday July 25th afternoon has 3ft SSW swell with offshore NE wind at 16 mph. Sunday July 26th is even better for the stronger surfer: 4ft from the SSW and S, with offshore winds all day. The energy is right around 700. This is where the bigger swells start hitting, and it’s still clean. For a beginner, 4ft is fine, but as it pushes toward 5ft, it might get a bit much.
After that, the swell slowly backs off through the end of July and into the first days of August. The last week has some small, clean waves but nothing that will get the heart racing. The last day, July 31st, is a write-off with only 1ft and weak energy.
So, overall: the best bet is Thursday July 23rd morning for that perfect combo of long-period swell, clean conditions, and solid energy. The Saturday July 25th and Sunday July 26th are the standouts for a bit more push. Keep an eye on the wind, and you’ll get some good ones.
Stay stoked.

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.
