The Lowdown
Alright, I’m looking at the charts for the next couple of weeks, and honestly, it’s a pretty quiet run for us here. We’re checking out Kiholo Bay, a beach and point setup, and it’s usually pretty consistent, but the forecast is a long stretch of flat or tiny waves. We’re talking a solid gap from now, basically through the end of August and into early September, with almost nothing rideable. The first few days are showing zero swell energy (0), and glassy conditions Wednesday afternoon on the 26th with water temps sitting at 82°F, which is a touch warmer than normal for this time of year. But it’s flat, so you’re just floating.
We’ve got a real dry spell here. From the 27th through the 31st, we see a few tiny pulses – waves around 0.3ft to 1.0ft, mostly from the west or southwest, with periods that are all over the place, from 8 seconds up to 18 seconds. That 18-second period on the 29th morning is a long-period groundswell, but it’s only 0.3ft, so it’s more of a ripple than a wave. The combined energy numbers are all in the single digits or low double digits, way below 100, so weak energy across the board. The wind is mostly light or glassy, especially on the 29th afternoon with rain showers and glassy conditions, but it doesn’t matter when there’s no swell.
We do see a slight uptick around the 10th of September, Thursday afternoon. The swell builds to 2ft from the west, with a 14-second period, and the combined energy hits 152 (moderate). The wind is cross-offshore from the ENE at 16 mph, keeping it clean. But it’s still a tiny wave, poor surf conditions overall. The water temp anomaly is no longer listed, so no news there.
The best option in this whole 16-day window? I’d have to say that Thursday afternoon, 10th of September, is the standout. It’s the biggest swell we see, with clean conditions. But honestly, it’s a slight standout in a very flat period. The waves are only 2ft, and while it’s the best we’ve got, it’s really only for the dedicated longboarder or someone just wanting to get wet. The crowd factor at Kiholo Bay can sometimes be an issue, but on a day like that, I doubt you’ll have much company.
So, for the next two weeks, it’s mostly a waiting game. The surf is poor, and there’s a long stretch of nothing. Keep your eyes on that 10th of September, but don’t get your hopes too high. This is a quiet period for the area.

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.
