The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts for Empty Lots, and I gotta be straight with you—this 16-day window is a tough one. For a spot that’s an advanced reef setup, it’s mostly a story of wind messing things up. We start with a big gap of nothing worth paddling out for. From Friday the 31st of July right through to Monday the 3rd of August, it’s all strong winds and poor conditions. The first chance we get to even think about it is a tiny window on Tuesday the 4th of August.
On Tuesday afternoon the 4th of August, things get a little interesting. We’ve got a 4ft swell from the ENE, super long-period at 11 seconds, which is proper groundswell. The wind goes light, almost glassy, and it’s cross-offshore, so that should polish it up clean. The combined energy is 356—moderate—so there’s a bit of push. For a reef like Empty Lots, that long period could make for some lined-up walls, but it’s only advanced out there, so don’t expect it to be easy. Crowds are possible at this spot sometimes, and with a 4ft swell, it’s not gonna be a circus.
Then we hit another long dry spell. From Wednesday the 5th of August all the way to Thursday the 13th, it’s back to cross-shore winds, lumpy chop, and poor surf ratings. A few mornings show marginal conditions, but the wind’s never your mate. It’s a real grind.
The real standout—and I mean the only one worth getting excited about—comes on Friday the 14th of August afternoon. We get a 2ft swell from the south, with a very long period of 19 seconds. That’s a deep ocean groundswell. The wind switches to a light westerly, cross-offshore, and it’ll be clean. The combined energy jumps to 668, which is moderate but with that period, it’ll have way more push than the height suggests. This is the pick of the entire outlook. At a reef, that long-period south swell will wrap in nicely. It’s not big, so it’s user-friendly for the advanced crew, but with 2ft, even some strong intermediates might get a look. Just remember, it’s a rare break that’s inconsistent—so you gotta be there when it lines up.
After that, Saturday the 15th of August morning shows a 3ft south swell with a 16-second period, but it’s onshore wind, so it’ll be bumpy. Not worth the drive.
Water temp? I don’t have a number here, but the anomaly says it’s pretty average for the time of year, so no wetsuit surprises.
Bottom line: there’s a tiny window on Tuesday the 4th of August afternoon, and then a solid chance on Friday the 14th of August afternoon. Everything else is a write-off. Keep an eye on the long-range promise of that 14th—it’s the one that could deliver, but don’t book your flights just yet.
Rusty.

Information about the Empty Lots Surf forecast
The above surf forecast table for Empty Lots provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Empty Lots can be found by selecting the local surf guide option on the grey menu. Our Empty Lots 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 (Empty Lots) 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 Empty Lots 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.
