The Lowdown
Right. Pull up a seat, grab a coffee. Rusty here. Let’s talk about Empty Lots.
First thing you gotta know – this is a reef break, exposed to the swell. It’s a fairly consistent wave, but it’s an advanced-only spot. And right now, it’s giving us nothing. The next week and a half are a total write-off. From Saturday the 22nd of August right through to Monday the 31st of August, the call is “poor surf conditions” every single session. The wind is hammering cross-shore at 18 to 25 mph, building lumpy cross-chop. The water temp is sitting at 81°F, which is about normal for the time of year, so nothing weird there. The swell energy is moderate, with combined energy values in the 400-600 range, but it’s all wind-affected slop. The swell is mostly short-period stuff around 7 seconds, or longer ones from the south that are getting mangled by that wind. There’s a couple of days where the swell height bumps to 5 ft, but with that cross-chop, it’s just messy. Not worth paddling out.
Then we hit the 1st of September – a Tuesday morning – and we get our first little flicker of hope. The swell is 6 ft from the east, period 9 seconds, and the energy jumps to 978. The wind drops to 12 mph, still cross-shore, but the comment changes from “poor” to “marginal.” It’s still not good, but it’s a shift. The afternoon is a bit smaller with a longer period from the south.
Wednesday the 2nd of September is where it gets interesting. The morning is still marginal, with a light breeze at 6 mph and a 3 ft south swell, period 17 seconds. But the afternoon – Wednesday afternoon – that’s the standout. The wind backs off to a gentle 9 mph from the NE, going cross-offshore, and the comment says “expect very good surf conditions.” The swell is 3 ft from the south, period 16 seconds, with moderate energy at 775. That’s a long-period groundswell, which will wrap in nicely at a reef like this, giving you clean, lined-up waves. The wind being cross-off means it’s going to be smooth. This is the best session on offer, no question. If you’re an advanced surfer, be there.
Thursday the 3rd of September, the wind swings onshore from the SSE at 9 mph, and the swell jumps to 5 ft from the ENE, but it’s short-period at 8 seconds. The morning is poor, the afternoon is only marginal with a risk of thunderstorms. The rest of the 16-day window from the 4th to the 6th of September is back to no good – strong cross-shore winds, small swell, and the word “poor” again. The wind on the 6th hits 40 mph from the NE, which is a gale. Even if it’s cross-offshore, that’s way too much for a paddle board. That setup is more interesting for kite surfers than paddle surfers.
So, to sum it up: sit tight for the first week and a half. There’s a long gap of nothing. Then on Wednesday afternoon the 2nd of September, Empty Lots has a real chance of being clean and fun. That’s your one golden window. The rest of the window after that is a bust. Don’t hold your breath.
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.
