The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking at Big Beach over the next couple of weeks.
First off, it’s a slow start. We’ve got a bit of a wait on our hands for anything worth getting excited about. The first few days offer tiny, weak swells; nothing really doing. The water temp is sitting about average for this time of year, so no nasty surprises there.
Monday the 3rd is a write-off. Tiny 1ft to 2ft swells from the south-southwest and south, with a weak energy reading (50). The wind is a light cross-off, but the wave comment says it all – poor surf. Not worth paddling out.
Tuesday the 4th and Wednesday the 5th are much the same story. Swell heights are stuck between 1ft and 2ft. The energy is still low (93 Tuesday morning, 76 Wednesday morning). The one bright spot? Tuesday morning is glassy – that’s a real treat for the eyes. But the waves are just too small to ride.
Thursday the 6th and Friday the 7th are still small, with the swell hanging around 1ft. The energy starts to build a little, hitting 167 on Friday morning, but the period is getting long (14 to 20 seconds), which for a beach break like this can make things a bit tricky and straight. Friday afternoon is a loss with 25 km/h cross-off winds.
The standout window starts to appear on Saturday the 8th. The swell is still only 1ft, but the energy is climbing (280) and the period is a solid 18 seconds. Morning has light cross-off winds and the forecast is for good surf. It’s small, but it’s clean and the groundswell has some push. This is the first real glimmer.
Sunday the 9th and Monday the 10th keep the pattern going. Swell ticks up to 2ft by Monday morning, with energy hitting 301. The wind is gentle, so it’s clean. The afternoon of Monday the 10th gets messy with 25 km/h winds, so get it in the morning.
Now, if you want the best of the whole outlook, lock in Wednesday the 12th. The swell jumps to 3ft from the south, with a period of 18 seconds and a very strong energy reading of 874. The forecast says very good surf conditions. The wind is a light cross-off, keeping it clean. This is the one. It’s not huge, but the quality, consistency, and energy are all there. The crowd factor is listed as "sometimes", so you might have some company, but it’s worth it.
Thursday the 13th and Friday the 14th are still solid with 3ft swells, but the energy drops off a bit (641 Thursday morning) and the afternoons get a bit iffy with stronger winds and marginal conditions.
The second week, from the 15th onwards, fades out. Swell drops back to 2ft to 3ft, winds get stronger, and the energy falls away. Tuesday the 18th has a bit of offshore wind and a pulse of 2ft, but it’s a long way out and the overall trend is down.
So, to sum it up: the first week is a slow burn, but Saturday the 8th through to Wednesday the 12th is your window. Wednesday the 12th is the standout – clean, 3ft south swell, and plenty of energy. Don’t miss it.
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.
