The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for Kiholo Bay over the next couple of weeks.

Honestly, it’s a pretty flat stretch ahead. The first few days kick off with some small, long-period WNW swell, but the wave comment calls it "poor surf conditions" right from the start, and that’s the story for the entire 16-day window. There’s a gap from the very beginning—no real surf worth paddling out for. The first record shows Friday morning, 17 July, with a 2ft swell from the west at 14 seconds, but with a score of 0/10, it’s just not happening. That moderate wave energy (203) is there, but it’s not translating into anything rideable. Water temp is 80°, which is about average for this time of year.

The rest of the period just fades out. By Saturday the 18th, the swell drops to 2ft, and while there’s a glassy moment on Saturday afternoon, the waves are tiny and the comment says "surfable waves but very ordinary conditions." That’s the best we get, and it’s not saying much. Sunday through Tuesday, the swell keeps shrinking—1ft, then 1.0ft, then 0.7ft. By Wednesday the 22nd, there’s absolutely no swell at all, and that flat spell runs right through to the end of the month. There’s a tiny blip of 0.3ft from the west on 26 July, and another 0.3ft southwest swell on 30 July with a very long 17-second period, but the energy is next to nothing (12) and the break is "poor surf conditions."

Kiholo Bay is a beach and point setup, and it’s fairly exposed to the WNW, which matches the optimum swell direction. But honestly, with no swell of any consequence and mostly cross-onshore or glassy conditions on tiny waves, there’s nothing to get excited about. The consistency is there, but the waves just aren’t. For the first few days, you might get a knee-high bump, but it’s not worth a trip. After that, it’s a blank run of over a week. This kind of flat spell isn’t unusual for the area, so don’t sweat it. Forecasts can change, but right now, I’d leave the board at home.

Signing off, 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.
