The Lowdown
G’day, Rusty here, and let me tell you, it’s been a bit of a wait for something decent at Empty Lots. For a solid five days, from the 19th through to the 23rd of August, the options are basically zip—weak, messy, and cross-shore chop rules the roost. The water’s sitting at a typical 80.6° for this time of year, so nothing weird there, but the waves are just not playing ball.
The first real glimmer shows up on Friday afternoon the 21st. We’re talking a tiny 2.6ft SSW swell with an offshore wind turning glassy. The combined wave energy is moderate (366), but the real win is that the wind goes dead calm—glass-off conditions. It’s not big, but if you’ve got a log, that’s the session.
Things start to get interesting on Wednesday the 26th. That afternoon sees a 2.6ft S swell rolling in with a very long 18-second period and light cross-offshore wind (NNE). The energy is strong (660), and the comment says “very good surf conditions.” This is a reef break at Empty Lots (Big Island), and that long-period groundswell loves a reef—expect clean, lined-up waves. The crowds are “sometimes,” so you might have company, but it’s worth it.
The standout, though, is the Thursday the 27th. Two sessions pop. In the morning, a 4.3ft S swell (17-second period) with light cross-onshore wind and a combined energy of 1092—that’s strong. Afternoon cleans up with the same S swell at 3.3ft and a light cross-offshore breeze (NNE). Both have that same “very good surf conditions” tag. For me, the Thursday afternoon is the pick: smaller but glassier, with the long-period swell wrapping into the reef beautifully.
After that, we hit a dry spell again from the 28th of August right through to the 2nd of September. Lots of messy E windswell with short periods and strong cross-shore winds—not for paddling. By Tuesday the 1st of September, the swell bumps up to 6.9ft from the east with a 10-second period, but the wind is still cross-shore, and it’s rating as “marginal.” That kind of size at Empty Lots with a messy wind is a big risk—definitely for experts only. The energy is very strong (1204), but the wind just ruins it.
So, bottom line: the real standouts are Friday afternoon the 21st for the glassy small stuff, and Thursday the 27th for the clean, long-period swell. Get out there for those windows.

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.
