The Lowdown
Alright, Rusty here with the lowdown on Big Beach.
It’s a slow start, so don't get your hopes up for the first few days. Saturday and Sunday the 18th and 19th are tiny, with weak swell barely hitting 2ft, and the cross-off breeze is making it feel even more ordinary. The water is a warm 80°, which is about what you’d expect for this time of year.
The turning point is Monday the 20th. We’ve got a 3ft S swell rolling in, but the wind is the real hero, going light offshore from the NE, right in the break’s sweet spot. Combined wave energy is moderate at 505, and with a 16-second period, you’re looking at proper groundswell lines. This is the best bet in the first week. The morning is clean and has some push, but it’s a consistent break, so you might be sharing the water.
From Tuesday the 21st through the end of the month, the swell hangs around 3ft to 3ft out of the SSW, with some solid energy in the 700s on certain days. The wind is mostly cross-off from the E or ENE, which is okay but not perfect. The 26th of July is a solid morning with a light breeze and a 3ft swell, and the afternoon picks up a proper offshore from the NE. That’s clean, ridable, day-in, day-out stuff.
Now, mark your calendar for Thursday the 30th of July. The morning is glassy, dead calm from the SSE, with a 7ft S swell. The period is a short 7 seconds, so it’s going to be a bit chunky and steep, not a long, smooth roller. The combined energy is strong at 667, so there’s plenty of power. This is a big wave, over 6ft, so it’s strictly for the experts. Beginners, stay on the sand. The afternoon stays clean with a 6ft swell, but that glassy morning session is the one to chase.
The first week of August winds down with smaller, cleaner waves, around 2ft to 3ft and a moderate offshore breeze. It’s a nice way to finish the run, but nothing to write home about.
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.
