Table - best surf conditions forecast for Big Beach over the next 16 days.


Alright, Rusty here. Let's take a look at what's on the table for the next couple of weeks.

First up, we've got Big Beach. It's a fairly exposed spot, and the water temp is sitting about average for this time of year. The good news is that for a beginner-friendly break, it's very consistent. The not-so-good news is that the swell is tiny for the foreseeable future. We're looking at a long run of small, weak waves from the south and southwest, barely pushing 1.6ft to 2.3ft. The combined swell energy is moderate at best, climbing from 148 to 382 in the first week, which is enough for a little push but nothing to get excited about.

The first few days, from Friday the 10th through Sunday the 12th, are pretty ordinary. The wind is a mix of cross-off and light offshore, which keeps the surface clean, but the waves are just too small and weak to offer much. The swell period is long, between 12 and 18 seconds, which means there's some groundswell energy, but at this height, it's mostly just a gentle bump. This is really a beginner's stretch, and even then, it's marginal.

Things look a little more interesting around Wednesday the 15th and Thursday the 16th. The swell direction swings to the west, and the combined energy jumps to 542 and 495, which is a decent step up. The height is still only 2.3ft, but the longer period from the west might give a bit more shape. The morning sessions look best with light east winds and clean conditions. It's still small, but for a beginner-friendly wave, this might be the pick of the first week.

The second week is a bit of a mixed bag. From Sunday the 19th to Tuesday the 21st, the swell drops back, with energy around 165 to 325. The standout here is Tuesday the 21st, when a slightly bigger pulse of 3.0ft from the south arrives, and the wind goes clean offshore from the northeast in the afternoon. The combined energy is 325, so it's still moderate, but the clean conditions and a little more size make it the best bet of the entire two-week run. The swell period is 14 seconds, so it's a proper groundswell, and the offshore wind will keep it clean.

Then we get a bit of a surprise on Thursday the 23rd and Friday the 24th. A very long-period swell from the south-southwest rolls in, with periods of 18 to 22 seconds. The height is only 1.6ft to 2.6ft, but the combined energy is solid, hitting 368 and 459. That long period means the waves will have real punch for their size, and they'll be lining up nicely on the sandbars. The morning of the 23rd with light east winds and the afternoon of the 23rd with moderate offshore winds from the northeast are excellent windows. This is a great example of a small swell that will feel much bigger due to the long period, and it's a true standout for the patient surfer.

Overall, the best on offer is Tuesday the 21st, with the clean 3.0ft south swell and offshore wind, and the long-period south-southwest swell on Thursday the 23rd and Friday the 24th. The rest of the time is small and marginal, but the consistency is there, so you can always find a fun little wave if you're not picky.

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.
