The Lowdown

Alright folks, Rusty here. Let’s be real about what’s on the menu for Kiholo Bay over the next couple of weeks. I’ve looked at the charts, and to be honest, it’s a pretty quiet stretch. We’re looking at a long run of tiny to flat conditions, so don’t be in a rush to wax up.

The one spot we’ve got on the radar is Kiholo Bay. It’s a beach and point setup that’s fairly exposed and likes the swell from the WNW. Water temps are sitting at 80°, which is right about average for this time of year, so no surprises there.

The outlook starts with a tiny bit of energy on Monday, July 20th. We’re talking a weak 1 ft swell from the WNW with a 12-second period. The combined energy is a measly 27 (weak energy), and the wind is on it in the morning. By Monday afternoon, the wind goes glassy, which is a nice thought, but the surf is still just too poor to get excited about.

From Tuesday, July 21st, all the way through until the morning of Thursday, July 30th, it’s a total blank. That’s over a week of absolutely nothing rideable. The combined energy drops to zero for most of that stretch. The wind does go glassy on a few of those afternoons, but you can’t ride glass.

There’s a tiny flicker of life on the afternoon of Thursday, July 30th. A 1 ft swell from the SW with a very long 18-second period shows up, pushing the combined energy to 49 (still weak). The wind is light and cross-shore. We then have another quiet spell until the afternoon of Sunday, August 2nd, when a similar 1 ft SW swell with a 13-second period bumps the energy to 48.

The last chance we see is on the morning of Monday, August 3rd, and into Tuesday, August 4th. A 0.7 ft WNW swell with a 15-second period. The wind is on it Monday morning, but by Tuesday afternoon, it goes glassy again. The energy is still very low.

Honestly, there’s no standout here. Nothing is big enough to even call "small." The best of a bad bunch might be the glassy afternoon windows on Thursday, July 30th, and Tuesday, August 4th, just because the surface will be clean. But with the swell so tiny and the energy so weak, it’s really only for the most dedicated loggers or someone who just wants to sit in the water.

For the beginners out there, the swell never gets above 1 ft, so it’s never too big for you. For the experts, well, there’s nothing to ride.

It’s a long, quiet stretch for Kiholo Bay. The kind of blank run that’s more normal for this area in the summer. Keep an eye on the forecast, because it tends not to stay this flat for long.

Rusty.

Information about the Kiholo Bay Surf forecast

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

Kiholo Bay is 89 km (55 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.
