The Lowdown
G’day, Rusty here. Let’s be straight with you – the next 16 days at Empty Lots are a mixed bag. For the most part, we’re staring down a whole lot of chop, cross-shore wind, and marginal conditions. The water’s sitting at 81°, which is bang on average for this time of year, so no surprises there.
We kick off Thursday 3rd September and it’s grim. A 6ft east swell, 8-second period, and a fresh 22 mph cross-shore easterly has the place all lumpy and messy. Combined wave energy is 954 – weak – and it’s just poor. Thursday afternoon doesn’t get any better. Friday 4th sees a shift: the swell drops to 4-5ft from the south with a longer 12-second period, but that 22 mph cross-shore easterly is still ruining any chance of clean waves. Energy climbs to 1240-1265, but it’s still marginal at best. Saturday 5th brings a 7ft east swell, 13-second period, and the wind backs off to 16-19 mph cross-shore. Energy jumps to over 2000 – moderate – but the cross-chop is a deal-breaker. Sunday 6th has a 7ft SSW swell, 12-second period, but the risk of thunderstorms and a 12 mph cross-shore wind keeps things marginal. Still, energy hits 2581-2852.
Now, here’s where it gets interesting – Monday 7th September. This is the standout. We’ve got an 12ft SSW groundswell with a 15-second period in the morning, and by the afternoon it pumps up to a massive 23ft from the same direction. Energy goes through the roof – 7051 in the morning and a staggering 23426 by the afternoon. That is very strong energy. Problem is, the wind swings cross-onshore from the ESE at 22-28 mph, so it’s messy. And honestly, at 23ft, this is only for experts. The afternoon session gets a top score for conditions, but that size is intimidating and the wind will make it wild. This is a big-wave day for the brave only.
After that, Tuesday 8th drops back to a 7ft south swell, 9-second period, and the wind turns cross-onshore from the SSW at 16 mph. It’s poor. The rest of the week is a write-off with small 3-3ft swell, short period, and fresh easterly cross-shore winds. The following Saturday 12th sees a 5ft east swell, 8-second period, and a gentle 9 mph cross-shore breeze – marginal but cleaner. Sunday 13th offers the best of the second week: a 6ft east swell, 9-second period, with a light 9-12 mph cross-offshore northeasterly and clean conditions. Energy is 620 – weak – but it’s rideable. Monday 14th has a 8ft east-northeast swell, 8-second period, and light onshore winds – not great but not terrible. Then Tuesday 15th September brings a real treat: a 4ft southwest groundswell with an absurdly long 21-second period, glassy conditions, and combined energy of 1486. That’s excellent for experienced surfers. The long period means it’ll be best at a reef or point break, but the size is manageable. After that, the swell drops off into the 3-5ft range with increasing cross-shore winds, so it fades out.
Overall, the only true standout is Monday 7th September for the sheer size and power, but it’s for experts only. The second-week highlight is Tuesday 15th with that glassy, long-period groundswell – a gem for those in the know. Crowds at Empty Lots can pop up sometimes, so keep that in mind. Otherwise, it’s a long stretch of mediocrity. Rusty out.

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.
