The Lowdown
Alright, this is Rusty. Let’s take a look at what’s going on at Empty Lots for the next couple of weeks.
To be honest, right from the start, it’s a rough go. There’s a big dry spell for the first week. The wind is howling out of the east-northeast, and it’s wrecking whatever swell is trying to push through. It’s a lot of cross-shore wind, lumpy chop, and the wave comment is just “poor surf conditions.” The scores are all zeros for the first six days. You’d be fighting the wind more than riding waves.
There’s some energy out there, with combined energy numbers hitting the 1400s and 1600s, but that’s all tied to a messy, short-period east swell with gale-force winds. That’s not surfable, that’s a washing machine. For a reef break, that wind and chop is a nightmare.
We finally get a tiny glimmer of hope on Saturday, August 22nd. The afternoon session shows a glassy, dead calm wind. The swell is tiny, only 3ft from the SSW, but it’s a long period of 16 seconds. That’s a clean groundswell, but it’s gonna be small and weak. The combined energy is only 431, which is very weak. It’s the best we get, but it’s still a marginal day.
This spot is an advanced reef, and it’s exposed to the SSE. The optimum swell direction is SSE, so that tiny SSW swell is a bit off-angle. The water temp is about average for the time of year.
The rest of the month into the end just fades back into onshore junk and small, weak swell. There’s a little bump at the end of August with a 7ft east swell on the 28th, but the wind is still a fresh cross-shore, so it’s still marginal. The combined energy is back up to 1511, but it’s a messy, east beast.
Honestly, for a spot that’s this exposed and consistent, this is a shocking run. It’s a blank period. There’s no standout. The only tiny window is that glassy Saturday afternoon, but the swell is laughably small. For a reef break, you’d need a lot more push. The setup looks more interesting for a kite surfer than a paddle surfer for most of this period.

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.
