The Lowdown

Alright folks, Rusty here. Let’s get straight into it. We’ve got a 16-day window, and to be honest, it’s not going to be a ripper. There’s a long quiet spell at the start, so don’t expect much for the first few days.

Okay, so the first real chance to get wet comes on Friday, August 7th at Big Beach. It’s pretty small out there, with waves around 1 ft coming from the SW. The wind is cross-off from the east at 16 mph, which is something, but the swell energy is weak (191) and the surf is just poor. It’s a beginner-friendly spot and very consistent, but there’s nothing here to get excited about. The water is a warm 80°, which is about average for this time of year, so at least you won’t need a thick suit.

The next few days are similar. Saturday, August 8th through to Tuesday, August 11th see a slow increase in swell, but it’s still tiny, in the 1 ft to 3 ft range. The wind stays mostly cross-off, and the energy is still moderate at best (topping out around 362). The waves are clean but very ordinary. You can paddle out for a few knee-high rollers, but don’t expect a proper wave.

Now, here’s where it gets a little interesting. Wednesday, August 12th is the standout. The morning session is the one to aim for. The swell jumps to 3 ft from the south, with a long 18-second period. That’s proper groundswell energy (879) and it’s going to push through with some real shape. The wind is offshore from the ENE at 9 mph – that’s clean, glassy conditions. This is the best the whole window has to offer. The longer period means the sets will be a bit more spaced out, but the waves will be well-formed and have some punch. It’s an intermediate-friendly size, but the quality will be there for anyone who’s keen.

The rest of the first week is a bit of a letdown after that. Thursday, August 13th and Friday, August 14th still have some south swell, but the wind picks up and the energy drops. By Saturday, August 15th, it’s poor, with strong onshore winds and messy conditions.

The second week stays quiet. From Sunday, August 16th through to Saturday, August 22nd, the swell is mostly under 3 ft. There’s a weird spike on Tuesday, August 18th where the morning shows 5 ft from the south, but with a short 6-second period, that’s just wind chop – it’ll be bumpy and weak. The energy is still moderate (349), but it’s not your friend. The wind swings offshore on the 18th afternoon, but the swell drops straight back down. The rest of the time is a mix of poor and ordinary conditions, with very little to recommend.

So, the bottom line: Wednesday, August 12th morning is your only true standout. That’s where you’ll find the cleanest, most powerful waves of the whole stretch. The rest is a long, drawn-out lull. It’s a quiet patch for the area, but it won’t stay this way forever – forecasts can change.

Stay salty,
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.
