The Lowdown
Hey, Rusty here, and I’m not gonna sugarcoat it – Empty Lots is looking grim for the next 16 days. This reef break gets swell, but the wind and chop are just wrecking everything. We’ve got a long stretch of poor to marginal surf, with only one session that might be worth a paddle.
Starting Friday, September 4th, there’s a 5ft S swell at 13 seconds, but that ENE wind is blowing 22 mph, making it a lumpy, cross-shore mess. The combined swell energy is 1368 – moderate – but the surf is poor. Saturday the 5th sees a bit more size, 7ft from the E in the morning, but again, 19 mph ENE cross-shore winds keep it rough. By Sunday the 6th, we get a glimmer: 7ft from the ENE in the morning, still cross-shore, but the afternoon brings a 7ft SSW swell at 14 seconds, with the wind dropping to 9 mph. The combined energy jumps to 3757 – strong – and the cross-shore is gentle, so it’s less lumpy. That Sunday afternoon is the best on offer, but it’s far from perfect.
Monday the 7th is a total loss – 10ft to 16ft of swell, but with a fresh cross-onshore wind and combined energy of 5814 and 12934, it’s just a big, windy mess for experts only. Tuesday the 8th has a risk of thunderstorms and a 7ft SSW swell, but the wind is off. The afternoon actually goes onshore with a 4ft SSW swell at 14 seconds, and the combined energy is 1016 – still marginal, but the wind is gentle. It’s the best we’ve got, but don’t get excited.
From Wednesday the 9th through to Saturday the 19th, it’s a long, dry spell. The swell drops to 2ft to 5ft, and the wind is relentless from the ENE at 16 to 22 mph, keeping the cross-shore chop lumpy. The combined energy is weak to moderate (419 to 1136), and the forecasts are all “poor” or “marginal.” There’s a tiny spike on Tuesday the 15th with a 3ft SW swell carrying a 20-second period – that’s a very long period groundswell – but with a fresh cross-shore wind, it’s just not happening.
The only standout? Sunday afternoon, September 6th – that 7ft SSW swell with a 14-second period and a gentle breeze is the cleanest it’ll get, but it’s still lumpy. Crowds are possible here, but with this quality, you’ll have the place to yourself. The water temperature is about average for the time of year.
It’s a rough patch, but this area sees these blank runs, so don’t lose hope – forecasts can change. For now, take a break.
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.
