The Lowdown

Alright folks, Rusty here. Let’s talk about what’s happening at Big Beach.

Overall, it’s a pretty quiet stretch. There’s a long run of small, weak surf, but a few sessions popping up in the first week of September might be worth the wait. Right now, there’s not much to get fired up about until the tail end of August.

The first real sign of life is Wednesday, 26 August. The morning is still nothing special, but by the afternoon we get a long-period groundswell from the SSW at 2ft with a 17-second period. That’s real energy. The combined energy hits 551 (moderate), and we’ve got offshore wind from the ENE at 12 mph. It’s a beach break, so that long period might make waves a bit fat, but with offshore wind it’ll be clean and fun for anyone who knows what they’re doing.

The absolute standout is Thursday morning, 27 August. Swell bumps up to 3ft from the SSW, still with a 16-second period, and the combined energy is a solid 844 (moderate to strong). Winds are light cross-off from the ENE at 9 mph, so the surf will be clean and the lines will be good. This is the best energy we see in the whole forecast window. The water is 81°, which is pretty normal for this time of year.

After that, it fades. We get a couple of decent windows on Tuesday, 1 September and Wednesday, 2 September with clean 3ft to 3ft swells, glassy conditions on the Tuesday morning, and light offshore breezes. The energy is moderate (around 490-569). Solid funboard or longboard waves.

The rest of the time is mostly small and ordinary – 2ft to 2ft swells with combined energy often under 300. The end of the first week of September brings a strong offshore wind event, with 37-40 mph winds on 6 September – that’s gale force. The swell is tiny, so that setup is more interesting for kite surfing than paddle surfing.

Crowds are possible at Big Beach, so keep that in mind if you aim for the better windows. The later sessions in early September are promising, but they’re a long way out and not a sure thing.

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.
