The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the coming weeks.
We’re looking at a pretty quiet stretch, to be honest. The first bit of actual surfable waves comes in on Tuesday, 14 July, but it’s nothing to get too excited about. The big picture is a small, long-period WNW swell rolling in, but it’s weak and the wind is a bit of a headache. The best bet of the whole window is that Tuesday afternoon, where you’ll find clean conditions with a cross-off breeze at Kua Bay, and the water temp is sitting at a normal 80°F for this time of year.
The standout session is Tuesday afternoon, 14 July. Kua Bay is cleaning up with a light SSW cross-off wind, so the surface will be nice and smooth. Swell is a tiny 2ft from the W with a very long 16-second period—that’s proper groundswell, which means long, drawn-out lines but a bit of a wait between sets. The energy is moderate (267). This is an intermediate spot, and with that small size, it’s fine for most. It gets crowded sometimes, so expect a few others out.
Wednesday morning, 15 July, is a write-off with a cross-on wind, but the afternoon clears up again with a similar 3ft, 15-second W swell and a cross-off, so that’s another decent option. Thursday, 16 July, is all cross-shore and ordinary, just marginal waves at best. Friday, 17 July, has a morning cross-on and a small 2ft, 14-second swell with dropping energy (203), so it’s not great. By the weekend, 18 and 19 July, the swell drops off a cliff—down to 2ft and then 1ft, with next to no energy (87 and 34). That’s the end of the run.
From Monday, 20 July, right through to the end of the forecast on 29 July, it’s flat. There are a few days with tiny little bumps of 0.7ft or 2ft, but the wind is all wrong, the period is short, and the energy is either zero or single digits. Honestly, it’s a dead zone. That’s 10 days of nothing, which is a bummer, but it’s not unusual for this area to go quiet. The only thing worth mentioning is a very small 2ft, 6-second NNE windswell on Saturday, 25 July, but it’s short-period junk and the wind is cross-shore, so not worth paddling out for.
So, to sum it up: your only real window is Tuesday afternoon, 14 July, through to maybe Wednesday afternoon, 15 July. After that, put the board away and wait for a better forecast.
Rusty.

Information about the Kua Bay Surf forecast
The above surf forecast table for Kua Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kua Bay can be found by selecting the local surf guide option on the grey menu. Our Kua Bay 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 (Kua Bay) 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 Kua Bay 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.
