Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let's have a look at what Kua Bay has cookin' for us over the next couple of weeks.
Well, I gotta be straight with you – this is a tough one. We're looking at a long, quiet spell before anything even thinks about showing up. The water's a touch warmer than normal for this time of year, sitting at 28°, which is nice, but that's about the only excitement for a while.
For the first week, from now through to about the 11th of July, it's pretty much a flat calm. We're talking tiny dribbles of swell, nothing over 1ft, and mostly coming from the West. The energy is almost non-existent, with readings as low as 2 and 5. You'd be floating out there. There are a few glassy moments, like Monday morning the 6th and Tuesday afternoon the 7th, but with no waves to surf, glassy conditions don't mean a thing.
Things start to get a little more interesting around the 12th of July. That Sunday afternoon we see the swell bump up to 1ft from the Southwest with a long 16-second period, and the energy jumps to 143. It's still described as "surfable waves but very ordinary conditions," so don't get too excited. Then Monday the 13th and Tuesday the 14th see the swell building. Tuesday afternoon the 14th is the first time we get a sniff of something real: 3ft from the West, a very long 17-second period, and the energy climbs to 381. The wind goes clean and cross-off from the SSW. That's your first real chance, but the forecast still calls it marginal.
The standout, as far as anything can be a standout here, looks like Wednesday the 15th of July through Thursday the 16th. Swell holds at 3ft from the West, period stays long at 15-16 seconds, and wave energy is a solid 326 and 318. The wind is light, but it's mostly cross-onshore or cross-shore, so not perfect. For a spot that needs a WNW swell to be at its best, this W swell is off-angle, and the long period might make it close out if it's breaking too straight.
After that, it fades fast. By the 17th and 18th, we're back down to 2ft and 2ft with energy dropping below 150. The 19th and 20th are even smaller.
So, the honest truth? If you're desperate for a paddle, Tuesday afternoon the 14th through Thursday the 16th is your window. It's small, it's for intermediates at best, and the conditions aren't ideal. The swell is weak (energy peaks around 381) and the direction doesn't match what Kua Bay really wants. It might offer a few fun ones for the patient crew, but nobody's charging out of the water screaming. For the rest of the forecast, leave your board in the car.

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.
Kua Bay is 97 km (60 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
