The Lowdown

Alright, let’s talk in feet and miles.

Starting with Empty Lots. It’s a reef break, exposed, and usually pretty consistent. But this 16-day run is frustrating – a lot of wind, only a couple of clean windows.

Right now, on Friday the 21st of August, we’ve got a pulse. The morning has a light SSE breeze, 2-3ft SSW swell with a long 17-second period. Water temp is 81°, which is normal for the time of year. Moderate energy (408). It’s marginal. But Friday afternoon is the real deal: the wind goes glassy out of the SW, the same 2-3ft SSW swell holds at 16 seconds, and energy is at 355. Clean, glassy, and that long period will wrap nicely into the reef. This is your best wave in the first week. Crowds can show up sometimes, but for this quality, it’s fine.

From Saturday the 22nd of August through to Saturday the 29th of August, it’s a write-off. A relentless ENE wind – 18 to 25 mph – destroys the surface. The swell hangs around 2-5ft from the SSW or S, but the chop is brutal. Energy levels bounce from moderate to strong, but it doesn’t matter. Saturday the 29th afternoon gives a brief reprieve with a cross-offshore NE breeze at 18 mph, cleaning up a 3ft E swell. Energy is strong at 735, period 14 seconds. It’s the cleanest in days.

Sunday the 30th of August and Monday the 31st bring more size. Sunday afternoon shows 5ft E swell at 13 seconds, energy cranking to 1097, but it’s messy. Monday the 31st afternoon is the one for experts: 10ft from the ENE, 11-second period, and a cross-offshore NE wind at 15 mph cleaning it up. Energy is very strong at 2138. This is heavy reef wave territory – expert-only. Crowds are likely. This is the standout of the second week.

Tuesday the 1st of September keeps the size but the wind screams at 28 mph cross-offshore. The swell drops to 7ft ENE by afternoon, energy still strong at 1401. Wild, clean, but howling. After that, the swell fades and the wind goes onshore or cross-onshore through to Saturday the 5th of September, with energy dropping to moderate. Nothing special.

So, for the best shots: Friday afternoon the 21st of August – glassy, clean, 2-3ft long-period SSW groundswell at Empty Lots – and Monday afternoon the 31st of August for the big wave crew, 10ft ENE with a clean cross-offshore wind. Everything else is wind-chop or average.

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.
