The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got on the horizon.
Honestly, right now it’s pretty grim. The start of this 16-day stretch is a write-off for decent waves. We’re looking at a solid run of poor to marginal surf right through the first week and into the second. For the most part, you’ll be staring at small, weak swell and cross-shore winds that just chop it all up. The water temp is sitting at 82°F, which is pretty much dead average for this time of year, so at least you won’t freeze while you’re doing nothing.
The only spot on the radar is Empty Lots, a reef break that’s fairly consistent but tricky – it’s advanced territory. The whole period is a battle with cross-shore winds. Not much clean, lined-up surf until we hit Wednesday the 23rd of September. That morning, the wind finally turns cross-offshore from the NE, and we get a bump in energy with a 6ft swell from the ENE, period around 9 seconds. The combined wave energy jumps up to 1160, which is solid. It’s not perfect, but after a dry spell, it’s the most promising window. The wind will clean it up, and that reef should start to hold shape. Expect crowds here as it’s the only game in town and it’s a known spot that can get busy. The swell direction is ENE, which isn’t the absolute optimum (we want SSE), but it’s workable.
That Wednesday morning is the standout. The afternoon holds up too, with 5ft from the E, still clean with that cross-off breeze. Get on it before the wind swings back onshore later in the week.
Beyond that, the last few days of September and into the 27th fade back into small, weak chop. Nothing else to get excited about.

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.

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.
