The Lowdown
Alright, Rusty here. Let's have a look at what's cooking for the Kiholo Bay area over the next couple of weeks.
Honestly, it's a tough outlook, folks. We've got a long stretch of flat or near-flat conditions. The first real pulse of swell doesn't show up until Monday, September 7th, but even that is marginal.
The standout, if you can call it that, is Monday, September 7th at Kiholo Bay. We see a moderate-sized SW swell building through the day, starting around 3ft in the morning and bumping up to 5ft in the afternoon. The combined swell energy hits 466 in the morning, climbing to a solid 765 in the afternoon, which is a decent push of energy. The catch is that the wind is cross-on all day, from the W and WSW at 6 mph. It’s not howling, but it will put a bit of a crinkle on the face. Still, it’s the only real window of rideable waves in the whole forecast.
Tuesday, September 8th offers a similar-sized swell, 5ft to 5ft from the WSW and W, but the wind is still cross-on. The wave quality remains marginal.
After that, it's a long, drawn-out decline. From Wednesday, September 9th right through to Saturday, September 21st, we're looking at tiny, weak swell. Combined energy values drop to double or even single digits – that's barely a bump. The water temp is sitting around 82°, which is about average for this time of year, with no major anomaly to report.
There are plenty of glassy mornings and aftertimes in that second week, especially around the 10th and 11th, but with swell heights of 0.7ft to 1ft and periods all over the shop, there's simply nothing to surf. The swell direction is mostly SW, but it's just too small to do anything with.
So, bottom line: Monday, September 7th is your best and only real bet, but don't expect perfection. After that, the board stays in the car. It’s a classic flat spell for the area. Forecasts can change, but right now it's looking lean.
Stay 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.
