The Lowdown
Right then folks, Rusty here. Let's be straight with you – we've got a tough run ahead. Empty Lots is a reef break that's exposed to the south-southeast swell, but over this 16-day window, the conditions just aren't lining up for a quality session. The wind is locked in from the east-northeast almost the whole time, blowing cross or cross-onshore, which is going to keep things lumpy and messy.
We kick off on Monday the 14th with a tiny 2 ft SW swell, but the cross breeze and a weak combined wave energy of only 311 makes it a no-go. Tuesday and Wednesday get a little more push, with the swell building to 3 ft from the south-southwest, and the energy rising into the moderate range (around 534-746), but the wind stays cross, keeping the surface choppy. Water temp is sitting right around average for this time of year at a comfortable 81°.
Honestly, from Thursday the 17th right through to Sunday the 28th, we're in a real slump. The wind picks up, gusts regularly hitting 18-28 mph, and the swell stays small or gets blown out. There's a brief moment on Thursday afternoon the 17th where the swell jumps to 6 ft from the east, but with a short, weak period of 10 seconds and fresh cross-winds, it's just a messy, lumpy mess. The combined energy might hit 1222, but without clean conditions, it's not worth paddling out.
This being a reef break, those cross-shore winds are just as bad as onshore. The whole setup looks more interesting for kite surfing than paddle surfing for most of this period. There's a lot of days here with poor surf conditions, and a few with marginal surf forecast.
The one small glimmer, and I mean *small*, comes right at the end. On Monday the 28th afternoon, we see a shift. The wind drops to a glassy 3 mph from the east-northeast, and we get a clean, lined-up 2 ft SW groundswell with a long period of 18 seconds. The combined wave energy is a solid 690, suggesting enough push for the better-formed waves on the reef. The report even says "expect very good surf conditions." This is the only standout in the whole two weeks – if you can, save your energy and wait for this late window. It’s the only time you'll find clean, glassy waves at Empty Lots.
Take it easy,
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.
