The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Kiholo Bay over the next couple of weeks.
This is a classic case of a slow start. The first week and a half is pretty much a write-off for any decent paddle surfing. We're looking at a long gap of poor conditions, with tiny, weak swell and mostly onshore or cross-shore winds. The energy is barely registering – you'll see values as low as 9 to 16 (weak energy). You'd be better off with a floatie than a board. There's a little window on Sunday the 9th afternoon where the wind goes glassy, and we get a tiny 1ft WNW swell, but it's still pretty ordinary. The water temp is sitting at 81°F, which is about average for this time of year, so at least you won't need a wetsuit while you're sitting there waiting for nothing.
Things start to look a bit more promising from the 14th onwards. The real standout is going to be Friday, August 14th. We've got a clean 3ft swell from the WNW with a nice long period of 15-16 seconds. That's proper groundswell, and it's bringing moderate energy (390-400). The wind is forecast to be glassy, both morning and afternoon, which is exactly what you want. For a spot that usually takes a bit of swell to get going, this is a solid session. The following day, Saturday the 15th afternoon, also looks good with a 3ft W swell and glassy conditions, though the energy is a touch higher (435). It's still a clean, fun-sized wave.
For a spot like Kiholo Bay (Big Island), which is a beach and point setup, this longer period WNW swell is going to wrap in nicely. It's a consistent spot, but it can get pretty crowded. When it's clean like this, expect the lineup to be busy. The morning of the 14th and the afternoon of the 15th are your best bets for the whole outlook. The swell is small, so it's perfect for logs and funboards, and there's nothing too gnarly for an intermediate.
All in all, it's a long wait for a couple of good days. The early part of the outlook is a total dud, but the second weekend has a couple of tidy windows to get wet.
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.
