The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the outlook for our spot is looking pretty bleak for a while.
We’re looking at the next couple of weeks at Kiholo Bay, and honestly, there’s almost nothing to get excited about for a long stretch. The water’s sitting at a warm 81°, which is about average for this time of year, so at least the dip won’t be cold.
We kick off with a big gap. From Sunday the 2nd all the way through to Thursday morning the 13th, it’s just a write-off. We’re talking flat spells and tiny, weak dribbles that barely register. The first 11 days are plagued with tiny swell, a lot of onshore wind, and virtually no energy (combined energy under 100). It’s a whole lot of nothin’.
Finally, there’s a tiny flicker of hope on Thursday afternoon the 13th. We get some glassy conditions with a 1ft swell from the WNW, but it’s a long-period groundswell at 16 seconds. That’s a long wait between sets, but the clean surface will be a welcome sight after all that. The energy is still moderate at best (152).
The real standout, and the only time I’d say it’s worth paddling out, is on Friday afternoon the 14th. The swell bumps up a touch to 2ft from the west, with a 15-second period. The wind goes glassy from the NNE, and the combined energy hits 296. That’s the best push of the whole window, and clean conditions to go with it. For Kiholo, that’s as good as it gets in this forecast.
Saturday the 15th has a similar size in the afternoon but with less energy, and by Sunday the 16th and Monday the 17th, the onshore winds ruin it again. So, if you’re keen, pencil in that Friday afternoon session on the 14th. Everything else is a hard pass.

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.
