Table - best surf conditions forecast for Kiholo Bay over the next 16 days.
Alright, Rusty here. Let’s have a look at what’s cookin’ for Kiholo Bay.
Straight up, this is a tough stretch. For the next several days, the swell is tiny and the energy is weak. We’re looking at a long, quiet run. The first real glimmer of hope doesn’t show up until Monday morning, July 13th, and even then it’s just barely surfable. You’d be scratching for anything rideable. The combined wave energy finally climbs above 100 (104) on that Monday morning, with glassy conditions and a tiny 1ft of swell sneaking in from the SW, period at a decent 15 seconds. That’s a long-period groundswell, so it might wrap in and offer a few clean lines at the point, but it’s small – not a standout by any stretch.
The action really starts to build mid-week. By Wednesday July 15th, the swell pushes up to 3ft from the west, with energy readings hitting 310. That’s moderate energy. Conditions are still a bit messy with cross-onshore winds, so it’s marginal. But then Thursday July 16th morning is where it gets interesting. That’s the pick of the whole 16-day period. We’ve got a clean 3ft west swell, with a long 15-second period, and the wind is glassy – dead calm or light offshore from the north. Conditions will be clean and the wave energy is solid at 294. This is the one to circle. The swell direction (W) lines up well with the optimum direction for Kiholo Bay (WNW), so the point should really start working. It’s a consistent spot, but remember, the crowd factor is “sometimes,” so you might have company on the better sets.
After that, it fades. Friday July 17th still has some clean 2ft waves, but the energy drops off, and by the weekend we’re back to small, weak surf. The second week is mostly flat, with energy readings in the teens and single digits. By Wednesday July 22nd and Thursday July 23rd, there’s literally zero swell forecast. A complete blank.
Overall, if you’re looking for the one true window, it’s Thursday morning, July 16th. Glassy, clean, waist-to-chest high west swell with that lovely long period. That’s your session. Before that, it’s a waiting game. After that, it’s pretty much done.
Keep it salty.
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.
