The Lowdown
Alright, Rusty here again, same spot but in feet and knots for you.
Empty Lots (reef) has water temps around 82°F, about normal for this time of year. Let’s get into it.
The first few days are tiny. Saturday the 12th and Sunday the 13th, you’re looking at waves around 1 to 2 ft from the SW, with periods over 15 seconds – that’s slow, long-period groundswell. The best of it is Sunday afternoon when the wind goes glassy (3 knots from the ENE). Combined energy is weak to moderate, maxing around 286. Crowds are sometimes a thing, but you’ll be lonely in these conditions.
Monday 14th through Wednesday 16th is a bust: cross-shore winds from 20 to 30 knots, messy chop, and swell under 3 ft. Not worth suiting up.
Thursday the 17th sees a jump to 6–6 ft from the ENE and east, but it’s short period (10 seconds) and lumpy with 30–35 knot cross-shore winds. Energy is strong (1159–1235), but it’s a choppy, blown-out mess. More of a kite day.
Friday the 18th drops to 4 ft from the SSW, with a better 17-second period, but still cross-shore at 25 knots. Marginal at best.
The best on offer – and I say that lightly – is Wednesday the 23rd of September. Morning has 6 ft of ENE swell, 10-second period, cross-shore wind at 20 knots, and energy at 1232. It’s the highest scoring window (2/10), but still marginal. Afternoon gets worse with 30 knot winds.
Later in the month, the 26th of September has a Saturday morning window with 3 ft of SSW swell, a 15-second period, and light offshore winds from the SE at 3 knots. That’s clean, but tiny. Good for a longboard if you’re keen.
Overall, Empty Lots is struggling. No proper standout sessions in the whole 16 days. The bigger swells are short-period and windblown, and the clean windows are too small. If you’re a beginner, the bigger days over 5 ft are too much, and the chop makes them expert-only. It’s a quiet stretch – forecasts can change, but for now, it’s a lot of waiting.

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.
