The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for the next couple of weeks.
Right off the bat, we’ve got a bit of a mellow start. The surf is small but there’s something to work with. The standout session looks to be the morning of Tuesday the 15th. We’ve got a clean 2ft groundswell from the SW with a period of 20 seconds, and it’s dead glassy. That’s a rare combo – the water is 81°, which is about average for this time of year. The energy is moderate (434), and that long period means the sets will be well-spaced and the waves will have some real shape. It’s a great window for a longboard or a fish.
The rest of the first week is a bit of a mixed bag. Wednesday the 9th starts with a clean 3ft swell from the SSW, but the wind is cross-off. It’s surfable, but nothing to write home about. Thursday the 10th drops right off to 2ft, and the wind picks up. Friday the 11th has a clean 2ft morning, but again, it’s small. The weekend of the 12th and 13th is pretty ordinary – small, with a bit of offshore wind on Saturday afternoon that’ll clean things up, but the swell is tiny (1ft to 2ft).
Then we get into the second week. Monday the 14th morning is flat with a 0.7ft swell, but the afternoon shows a nice pulse: 2ft with a 22-second period and offshore wind, giving it a bit of energy (276). Tuesday the 15th is the gem I already mentioned. Wednesday the 16th holds decent 3ft to 3ft SSW swell in the morning, with cross-off winds and moderate energy (427). It’s not the best of the run, but it’s clean.
The rest of the week from the 17th onward gets a bit messy. The swell is still around 2ft to 3ft, but the wind gets stronger, and the conditions become more marginal. The energy is still there (up to 539 on the 18th morning), but the wind is cross-off and gusty, so it’s not going to be the cleanest. The last week of the month sees the swell drop right off again, with only 1ft to 2ft, and the wind stays cross-off. There’s a little uptick on the 24th with 2ft SSW swell and moderate energy (311), but it’s nothing special.
Overall, if you’re looking for the best surf, make a plan for Tuesday the 15th morning. That’s the glassy, clean, long-period swell that’ll have the banks looking good. The rest of the time, it’s small and workable, but you’ll be scratching for a decent ride.
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.
