The Lowdown

Alright folks, Rusty here. Let’s get straight into it for Kiholo Bay. We’re looking at a long, slow stretch here.

Honestly, the next week and a half is a total bust. From now right through to around the 10th of September, there’s just nothing doing. We’re talking about a solid 12-day gap with barely a ripple. The water is sitting at a warm 82°F, which is pretty much what you’d expect for this time of year, but that’s the only thing going for it. You’ll get the odd day of glassy conditions, like Sunday morning the 30th of August, but with zero swell showing up, it’s just a flat, clean pond.

We finally start to see a pulse of energy arriving on Thursday the 10th of September. The combined swell energy hits 128 (moderate) by the morning, and it’s a 2ft groundswell from the west, with a long period of 13 seconds. That’s a proper groundswell. The best call looks like Thursday afternoon (10th Sept). The swell drops slightly to 2ft, still from the west with a 13-second period, but the wind flips to a glassy NNW. It’s only rated as surfable with very ordinary conditions, but that glassy wind is a huge positive. The energy is still decent at 134 (moderate), so it’ll be the cleanest, most rideable session in this whole outlook. Keep in mind, this is a long-period west swell for a spot that favours WNW, so it should wrap in nicely, but don’t expect perfection.

After that, Friday the 11th of September afternoon has a similar 2ft west swell, again glassy, but with slightly lower energy at 77. It’s another okay window, but Thursday afternoon is the standout. Everything after that fades back into tiny or flat conditions. For a spot that can be fairly consistent, this is a grim run. It’ll turn around eventually, but for now, don’t hold your breath.

That’s the story from the beach. Rusty out.

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.
