The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking for the next couple of weeks. I’ll be honest, the pattern here is not giving us much to get excited about. There’s a huge gap of nearly two weeks before anything remotely worth paddling out for shows up.
We’ve got a reef spot called Empty Lots that’s wide-open to swell, but the wind has been a real pain—mostly blowing from the east-northeast at 15 to 25 mph, creating messy cross-shore junk. Even when a little swell pops up, like Sunday the 9th with a 4ft east swell but a weak 7-second period, it’s completely ruined by the wind and described as poor. The water temp is about 81°, pretty normal for this time of year.
The only standout I can point to is way out on Saturday the 15th. The morning brings a solid 10ft easterly swell wrapping through at 9 seconds, with the wind shifting to the northeast at 25 mph, offering cleaner cross-off conditions. The swell energy is strong at 1810, and it’s described as clean. That’s the one to aim for, but it’s an expert-only wave at that size. The afternoon holds similar 10ft E swell and even more energy (2447), but again, you’ll need skill and patience. It’s a long way off, so don’t set your watch by it.
Otherwise, not much else. The wind is almost always blowing cross to cross-onshore, keeping the waves lumpy and uninviting. For most of this period, it looks like the setup might be more fun for kite surfing than paddle surfing, given the strong side winds and bumpy conditions. The swell direction rarely lines up well for Empty Lots either.
Stay patient, and if that Saturday the 15th holds up, it might just be worth the wait. Until then, don’t get your hopes up. Rusty signing off.

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.
