Alright folks, Rusty here. Let's take a good, hard look at what we've got for Kua Bay over the next couple of weeks. I gotta be straight with you – it's a bit of a slow dance, but there might just be a couple of moments where it all comes together.
Right now and for the next several days, the surf is barely a whisper. We're looking at tiny, weak energy (2) with flat spells. The water temp is sitting at 81°, feeling a touch warmer than normal for this time of year, which is nice for a paddle but not much else. There are long gaps where it's just not worth getting your board wet.
Things start to get a little interesting around the morning of Saturday, July 11th. We see the energy finally bump up into three-digit territory, hitting a moderate 112. The swell is from the west at 1 ft, but it's a long period of 14 seconds. The wind, however, is onshore from the WNW, so the quality won't be there. It’s a tease.
The first real standout, and honestly the best bet in the whole outlook, is Wednesday, July 15th afternoon. The stars align briefly. The combined swell energy is strong at 239, with 2 ft of west swell. The period is a solid 16 seconds – a proper groundswell. And the kicker? The wind goes glassy from the SSE. That's as clean as it gets. This is the one to circle on your calendar if you can. The only downer here is that you might have some company; crowds are sometimes an issue here.
Thursday, July 16th afternoon holds up, too. The energy is even stronger at 253, still with 2 ft west swell and a 15-second period. The wind turns cross-offshore from the SSW, keeping things nice and clean. Another solid session, but the glassy conditions on the 15th are really the pick.
After that, the energy fades back into the low to moderate range, and the wind gets wonky. By Tuesday, July 20th into the 21st, we're back to small waves with mostly weak energy, though a few mornings might see some cross-offshore winds for a clean look at small, weak swell (1.0 ft). Honestly, unless you're desperate for a splash, the second week looks pretty average.
So, to sum it up: it’s a slow start, a strong middle, and a weak finish. Your best chance for something memorable is that glassy session on the afternoon of Wednesday, July 15th at Kua Bay. Don't sleep on it.
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.
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.
