The Lowdown
Alright folks, Rusty here with a look at what’s on the cards for Empty Lots.
To be straight with you, the next week and a half is mostly a write-off. We’ve got a run of poor conditions that stretches almost all the way through to the end of August. The wind is a constant problem, mostly cross or cross-on from the east and northeast, and it’s just churning the place up. The swell that’s around is small and weak, and with that wind, it’s not worth paddling out for.
The one bright spot, and I mean the *only* one that’s got me a little excited, is Thursday the 20th of August. The morning session is still a bit dicey with a light cross-on breeze and the waves are small at 2 ft from the southwest with a super long 18-second period – that’s proper groundswell but it might not have the size to do much. However, the afternoon is where it’s at. The wind drops to almost nothing, turning glassy, and you’ll still have that 2 ft of clean, long-period SW swell. The wave energy is moderate (385), and for a reef break like Empty Lots that loves a long-period swell from the south, this could be a real treat. It’s a spot that can get crowded, so for that afternoon window, get in the water and enjoy it. The water temp is sitting at 81°, which is pretty normal for this time of year.
After that, it turns messy again with more cross-shore wind. As we head into the last week of August and the first day of September, the swell actually builds up a fair bit, with combined energy reaching four-digit values (1002 to 1255) and waves around 7 ft to 8 ft from the east. But the wind stays relentless – all cross-shore and stiff. It’s a real shame because that's a lot of juice, but it’s just going to be a messed-up, lumpy mess. That kind of setup with significant swell and strong cross-wind is arguably more interesting for a kite surfer than a paddle surfer. For us, it’s just marginal at best. The forecast is fairly solid for this extended run of poor conditions, so don’t hold your breath.
Rusty.

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.
