The Lowdown

Alright, let’s get into it. This is Rusty, and I’m looking at the next couple of weeks for Big Beach. Honestly, we’re in for a bit of a slow burn here. The first few days are a write-off – Saturday afternoon through to Sunday are just no good, with messy cross-off winds and tiny swell. You’re better off staying home or doing something else. That’s a rough start, but hang in there, because things start to turn.

Monday the 31st is where it finally gets interesting. Early morning, we’ve got clean conditions with a light offshore breeze out of the ENE, and a small but tidy 2ft south-west swell rolling in. The period is a solid 15 seconds, which is proper groundswell, and the combined energy is moderate but building at 299. Water temp is a warm 81°, which is pretty standard for this time of year, no real surprise there. It’s not going to blow you away on size, but it’s clean and rideable – a good one for the beginner-friendly crowd here, but keep an eye out as it can get a little busy sometimes.

Tuesday the 1st of September is the real standout of this whole outlook. Morning session sees the swell bump up to 3ft from the SSW, with a long 18-second period. The wind is light offshore from the NE, and the combined energy jumps to a solid 592 – that’s moderate energy but packing a punch for the size. This is going to produce some nicely shaped, lined-up waves. The offshore breeze will keep faces clean, and that long period means better shape, but fair warning: with periods that long at a fairly exposed beach break, the sets can be a bit walled and wait a while between them. Still, this is your best shot for the whole run.

Wednesday the 2nd holds similar size, around 3ft from the south, but the wind swings cross-off and gets a bit stronger by the afternoon, making it less perfect. Thursday the 3rd is back to clean morning conditions with offshore wind and 3ft swell, but the period drops a little, so it’s not quite as special.

After that, from Friday the 4th through to the middle of the second week, the swell drops back and things get ordinary. The waves are small, mostly 1ft to 2ft, and while the wind stays offshore or light, the energy is weak – most days sitting below 200. It’s surfable, but nothing to write home about.

Then, around Monday the 7th of September, we get another little pulse. The morning sees 3ft SSW swell with a 17-second period and a clean offshore breeze – energy at 561 (moderate). The afternoon is even better: 3ft from the same direction, a long 17-second period, and gentle offshore NE wind. The combined energy hits 687, the highest of the whole outlook. That afternoon session on the 7th is a true highlight, with clean, lined-up waves that’ll have some push.

The rest of that week stays small but clean, with the best being Tuesday and Wednesday mornings, offering 3ft with offshore winds. By Thursday the 10th and into the weekend, it’s back to small, clean but weak conditions – perfectly fine for a longboard or a beginner, but not going to get the heart racing.

If you’re an expert, there’s nothing over 3ft here, so keep your expectations in check. The standout days are absolutely Tuesday the 1st of September morning, and Monday the 7th of September afternoon. Those are the windows to paddle out.

Stay patient, keep an eye on the forecast, and I’ll see you in the water.

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.
