The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Straight up, it's a bit of a mixed bag for Empty Lots (reef). The water temp is sitting around 81°, which is pretty much spot on for this time of year, so no surprises there. We've got a bit of a dry spell at the start before things get interesting.
The first real window of opportunity looks like Wednesday afternoon, the 9th of September. We're looking at a 3ft SSW groundswell, with a period of 13 seconds, giving us a decent amount of energy (312). The wind is glassy, and that's a major positive – it'll be clean as a whistle. The swell direction is a bit off from the optimum SSE, but with no wind and a clean face, it'll still be fun on the sets.
Thursday the 10th is a write-off. A lumpy 5ft ENE windswell with a short 7 second period and a cross-shore wind? That's a mess. Not worth paddling out for.
The long-range outlook is a bit of a tease. Around Tuesday the 22nd of September, we see a solid pulse of E swell coming through – 7ft at 13 seconds. That's a lot of energy (2260) and it's a proper groundswell. The period is long, so it'll have some punch, but it's coming from the east, which is cross-shore at this spot. The wind is also a moderate cross-shore, so it won't be perfect. It's a big swell, over 5ft, so it's not for beginners, and the cross-shore wind will make it a bit of a battle. It's a promising day, but that wind is a real shame.
Honestly, for the whole 16-day window, there's no standout day that's firing on all cylinders. The Wednesday afternoon glass-off is probably the best you'll get for a clean, easy paddle. The bigger swells later on are all dealing with some cross-shore breeze. If you're a kiter, the windy days around the 20th to 23rd with that 7ft+ swell and strong cross-shore wind might look like fun, but for a paddle surfer, the conditions are just not lining up.
Keep an eye on the forecasts, though. It rarely stays poor for long around here.
Rusty.

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.
