The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way.
Well, I gotta be straight with you – this stretch is a tough one for the paddle crew. The whole 16-day window is pretty much a write-off for decent surf. We’ve got a long, dry gap from the start all the way through. There’s really nothing to get excited about.
The only spot on the radar is Empty Lots, a reef break that’s fairly consistent. The water temp is sitting at 81°, which is about average for this time of year, so no surprises there.
We kick off on Wednesday, the 12th, with a 3ft south swell at a super long 18 seconds. That’s proper groundswell, but the energy is only moderate (1043). The problem is the wind is howling from the ENE at 19 mph, cross-shore, and it’s gonna be lumpy and chopped. The quality is just not there. That afternoon, it’s a bit bigger at 4ft, but still messy.
Thursday the 13th and Friday the 14th are worse. Swell drops, the wind sticks around, and the scores are just zero. It’s poor, plain and simple.
Then it gets a bit wild. Saturday the 15th, the swell jumps to 8ft from the east, but with a short 10-second period and strong cross-shore winds at 25-28 mph, the energy is strong (1455-2017) but the surface is a mess. By Sunday the 16th, we’re looking at 13ft east swell with near gale-force winds. That’s dangerous, blown-out, and only for the truly crazy or the kite surfers – honestly, this setup looks more interesting for kite surfing than paddle surfing.
Things calm down a bit from Monday the 17th, but the swell drops back to 3ft or less, and the wind is still cross-shore and fresh. The rest of the run into the 27th is a mix of tiny south and southwest swells, with periods up to 18 seconds, but the energy is weak (under 500 most days) and the wind never really cleans up. It’s a consistent run of poor conditions.
So, bottom line: there’s no standout, no hidden gem, no session to circle on the calendar. It’s a bleak outlook for Empty Lots. Sometimes you get a blank run, and this is one of them. Forecasts can change, but right now, leave the board in the car and go do something else.
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.

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.
