The Lowdown
Alright, this is Rusty. Let’s have a look at what’s coming up for Big Beach over the next couple of weeks.
First off, the water temp here is sitting pretty average for the time of year, nothing weird going on.
We’ve got a bit of a slow start, but things kick off properly on Wednesday the 15th. The morning brings a clean 2ft swell from the west, with a long 15-second period, and a light cross-off breeze. The combined energy is pumping at 565 (moderate). It’s not a massive day, but it’s surfable and clean. The afternoon holds up similar size with a bit more breeze.
Thursday the 16th is more of the same in the morning – 2ft, west swell, clean. The afternoon gets a little messy with a smaller, shorter-period swell and questionable conditions, so aim for the early session.
Friday the 17th dips a little in size to 2ft, but the morning is still clean with light winds. The afternoon picks up a bit of a southerly pulse at 16 seconds, but the wind gets stronger, making it feel ordinary.
Saturday the 18th and Sunday the 19th are pretty flat and uninspiring – small, weak swells, and the wind is on it. The combined energy drops into the low 200s (weak). Not worth paddling out unless you’re desperate.
Now, here’s where it gets interesting. On Monday the 20th, a new southerly swell fills in, pushing 3ft with a 16-second period. The morning is clean with light east winds, and the afternoon actually turns offshore from the ENE, giving you a moderate offshore and clean look. Combined energy is back up to 505 (moderate). This is a solid day for the average surfer.
Tuesday the 21st is similar: 3ft in the morning, clean, light breeze. The afternoon gets a bit wind-affected, but the morning is the pick.
Then we hit a standout. On Saturday the 25th, the morning is glassy – yes, glassy – with a north wind at only 3 mph. The swell is 3ft from the SSW, with a very long 19-second period. Combined energy is a massive 1009 (very strong). This is the best on offer in the entire outlook. The long period means the waves will have real shape and power, and with zero wind, it’s going to be a dream session. The later afternoon holds up well too.
Sunday the 26th and Monday the 27th keep the 3ft to 3ft SSW swell going, but the wind swings back to cross-off, so it’s not as perfect as Saturday. Still very surfable.
After that, the last few days of the month and into the 30th show a slow decline. Smaller swells, more wind, and the energy drops off. The 28th is ordinary, with combined energy down to 187 (weak). The 29th and 30th have a bit of a pulse, but nothing to get excited about.
Overall, the clear standout is Saturday the 25th – morning glass with that long-period SSW groundswell. That’s the one to circle. The 20th and 21st are solid runner-ups.
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.
