Alright folks, Rusty here. Let's take a look at what Kiholo Bay has cookin' over the next few weeks.
Alright, let's be straight with you. The next week or so is lookin' pretty flat and sad, if I'm bein' honest. We've got a long stretch of weak, tiny surf and mostly dodgy winds. It ain't gonna be until Monday the 13th that we finally see a glimmer of hope.
The first real standout of the whole period is Monday morning, July 13th. We've got a small pulse of 1ft swell from the southwest, but the real story is the wind. It's gonna be glassy, just dead calm. That's a major positive. Sure, the swell is tiny, but with zero wind, you'll get some clean little peelers on the point. The combined energy is moderate at 124. Honestly, if you're desperate for a paddle and sick of lookin' at a flat ocean, that Monday morning window is your only real play.
Now, if you're willing to wait, Tuesday the 14th through Thursday the 16th sees the swell bumpin' up a bit, with waves around 2ft to 3ft from the west. The combined energy gets into that moderate range, peaking at 318. That's some grunt, but the wind is mostly a light cross-onshore, so the face is gonna be a bit bumpy. It's marginal, but it's something. The standout in this little run is probably Thursday afternoon, July 16th, when we get a light cross-shore wind from the southwest. The swell is 3ft from the west with a period of 15 seconds, which is a nice long-period groundswell. It'll bring some good shape, but those long waits between sets will be noticeable. This wave will be best for intermediate surfers.
Then it kinda fades again. Friday the 17th afternoon has a moment of glassy conditions with 2ft swell and moderate energy (148), worth a look if you're free. After that, things drop off into tiny surf and poor conditions for the rest of the period through to the 25th. It's a lot of days with combined energy down in the double digits or low triple digits.
So, bottom line: don't get your hopes up for a classic session. The absolute best bet is that glassy Monday morning, July 13th, for a clean if tiny wave. The Thursday afternoon, July 16th, has the most size and power, but the wind won't be perfect. It's a lean couple of weeks, folks.
Stay patient,
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.
