The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Big Beach over the next couple of weeks.
Right off the bat, I gotta be straight with you – the first week or so is pretty flat and underwhelming. We’ve got some small, long-period energy rollin’ in from the SSW, but it’s just not enough to get excited about. The water temp is sitting about average for this time of year, so no surprises there.
The real story starts to build around the second weekend. The 9th of August kicks off a promising run. Sunday morning, we’re lookin’ at a 2ft S swell with a 19-second period – that’s proper groundswell energy. The combined energy is a solid 406 (moderate), and with a light offshore breeze from the NE, it’s gonna be clean. That long period will mean longer lulls between sets, but when they come through, they’ll have some punch. This is a point break or reef setup kinda swell, but at Big Beach it’ll still offer some fun lines.
But the standout, the one you wanna circle on your calendar, is Monday the 10th of August. The morning session is where it’s at. We’re expecting a 3.3ft SSW swell with a 16-second period, and the combined energy jumps to 724 (strong). That’s a serious step up in power. Winds are light from the E, keeping it clean. This is the best on offer – real, surfable waves with some push. The swell direction is right in the sweet spot for the beach’s exposure.
After that, the 11th and 12th drop off a bit in quality and size, but the 13th and 14th keep things ticking over with 2.3ft S swells and good energy levels (around 400-500). The 15th of August is another one to watch – Saturday morning is shaping up with a 3.3ft S swell and a combined energy of 757 (strong). That’s a big, powerful swell, and if the winds play ball, it’ll be a cracker.
A word of caution: Big Beach can get crowded sometimes, so get in early for the best of it. The long-period swells (over 15 seconds) we see on the 9th and 10th can make the waves break a bit straight at a beach break, but with the size and offshore conditions, it’s still gonna be well worth the paddle.
So, the first week is a write-off. The real action is from the 9th of August onwards, with the 10th being the standout. Get ready.

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.
