The Lowdown
And now, in the old school imperial.
Alright, let’s size this up in feet. The early part of the run is tiny. We’re talkin’ ankle to knee-high stuff, maybe 1 to 2 feet on the sets. The swell is coming from the SW and SSW, with periods that get real long, up to 16 seconds, which is a proper groundswell. But at this height, it’s just a clean, glassy lake. The water temp is 80°, which is about what you’d expect for the season.
The real window opens up on Wednesday, the 12th of August. The swell pushes to a solid 3-4 feet (S, 17 seconds). The combined energy reads 966, which is good, solid power. The wind is a cross-off from the E, and the call is for “very good surf conditions”. That’s the one to mark on the calendar. Thursday the 14th is also a standout, with a 4-foot S swell and offshore winds from the ENE, giving you clean, organized lines. The rest of the week holds at around 3 feet, with offshore winds, making for good, fun waves.
Crowds are “sometimes” at Big Beach, so you won’t be alone, but it’s not a zoo. For a beginner, 3-4 feet is a bit of a push, so stick to the 3-foot days for a better time. It’s a beach break, so those long period groundswells (over 15 seconds) can make the sets a bit shifty, but the energy is definitely there.
Best on offer: Wednesday morning, the 12th of August. 3-4 feet of S swell, 17 seconds, and a clean cross-off wind. That’s the one.

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.
