The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table.
Right off the bat, we’re in for a quiet spell. The first real surf worth paddling out for won’t show up until Monday the 4th of August, and even then it’s tiny and ordinary. From now through the weekend of the 2nd and 3rd, it’s pretty much a write-off – small weak swell, mostly cross-off breezes, and energy barely ticking over. You’re better off waxing the longboard and waiting.
Things start to look up on Monday the 4th of August. Early morning at Big Beach, we’ve got 2ft of S swell, and that wind turns glassy. The energy’s still low, but it’s clean, and that glassy surface is a treat. It’s not going to blow anyone’s mind, but for a Monday session, you could do worse.
The real standout, the one to circle on the calendar, is Sunday the 9th of August through Tuesday the 11th. Sunday morning brings 2ft of SSW groundswell, period at 18 seconds – that’s proper long-period stuff, meaning shape and power. The combined energy jumps to moderate, and with a light breeze and clear skies, it’ll be clean. That’s the start of something.
But Monday the 10th of August is the pick of the whole run. Morning session: 3ft SSW swell, period 16 seconds, combined energy strong, and glassy conditions with a tiny NE breeze. That’s a beautiful combo – clean face, real push, and those long gaps between sets will make paddling out a breeze. Tuesday morning holds similar promise at 3ft, with energy still strong and light winds.
Crowds? Big Beach can get busy sometimes, so for that Monday glass-off, get out early. The swell direction (SSW) lines up well with the optimum for the break, and the long period means the waves will wrap in nicely.
Water temp is about average for the time of year – nothing weird, just normal.
After that peak, the energy fades through the second week, dropping back to around 2-2ft. Still clean enough for a longboard, but nothing that’ll get the heart racing.
So: the 9th, 10th, and 11th of August are your windows. Monday the 10th is the big one. Set the alarm.

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.
