The Lowdown
Alright, Rusty here. Gotta be honest, the outlook for Empty Lots is a tough one to write. This reef break is usually fairly consistent, but we’re in for a real dry spell.
The whole thing starts off rough. Saturday morning brings a fresh cross-shore breeze at 30 km/h and a lumpy cross-chop, making the 1.8m east swell look like a mess. The swell energy is strong (2043), but the 14-second period doesn’t help when the surface is that ugly. That nasty wind sticks around through Sunday and into Monday. By Monday morning, the swell is 2.3m from the SW, and the energy is up to 3934, but the wind is still cross-onshore. Monday afternoon is worse: 3.0m of swell, 30 km/h onshore wind, and very strong energy (5600). That’s not a surf session, that’s a beating. It’s definitely too big for beginners, and with that wind, it’s more of a kite-surfing setup than a paddle one.
Tuesday morning is a flicker of hope with a 1.2m SSW groundswell from a 15-second period, but the wind is onshore, and the quality is rated poor. The energy is still moderate (1622). Then the lights go out. From Wednesday the 9th all the way through the 14th, the swell drops under 1.5m, and the wind is a constant cross-shore or cross-off breeze. The energy dips into the 400- to 800-range, which is weak to moderate, and the swell periods are short, around 7 to 8 seconds. It’s just flat and blown out.
The only real glimmer comes on the 16th of September. Wednesday morning shows a 1.1m SW groundswell with a very long 18-second period. The energy is moderate (1098), and while the wind is a moderate cross-shore, the quality is marginal. That long-period groundswell will bring plenty of power, and at a reef, it could shape up nicely if the wind drops. It’s the best bet in the whole 16-day window, but it’s a long way off, so don’t book the trip just yet. Water temp is about average for this time of year.
After that, the wind cranks up to 35-40 km/h, and the run ends with a whimper. So, unless you’re desperate, wait for that 16th and keep your fingers crossed.
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.
