The Lowdown
Alright, this is Rusty. Let’s break down what Empty Lots has in store for us. The water temp is about 81°F, which is normal for this time of year, so no worries there.
We’re starting off on Sunday, August 9th, and it’s not pretty. We’ve got a 4ft E swell, but it’s short-period at 7 seconds, and that ENE wind is blowing at 16 mph. It’s a cross-shore mess with a cross-chop. The wave energy is weak (515). Monday and Tuesday are more of the same – the swell direction shifts to a longer-period SSW groundswell, but the wind stays nasty, and the conditions are poor.
Wednesday the 12th brings a jump in energy from a long-period S swell, 18 seconds, pushing the combined energy into the moderate range (1029 to 1152). But again, that fresh ENE cross-wind at 19 mph is just ruining it with a lumpy chop. This pattern holds right through to Saturday the 15th. There’s some size on Saturday afternoon with a 7ft E swell, but it’s still messy.
Now, here’s the one to get excited about. Sunday, August 16th, is the standout. The morning brings a solid 8ft E swell with a nice 13-second period, and the wind finally plays ball – a light cross-offshore from the NE at 13 mph. The wave energy is strong (2456) and it’s described as clean. This one’s for the advanced crew, as it’s getting big. The afternoon gets even better: a 10ft swell from the ENE with a cross-offshore breeze and a massive energy reading of 3341. That is the session to circle on your calendar. Expect a crowd, though, because this spot can get busy.
After that peak, it falls apart again. Monday the 17th and Tuesday the 18th are back to poor conditions with onshore and cross-onshore winds. We then drift through a long, flat spell with weak, short-period windswell and messy winds right through to the end of the 24th. The last week is basically a write-off for quality surfing.
So, to sum it up: you’ve got to grind through a week of chop for a chance at a proper, clean, powerful session on Sunday the 16th. That’s the one.
Rusty.

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.
