The Lowdown

Alright folks, Rusty here. Let's get real with you for a minute. The surf outlook for the next couple of weeks is pretty grim. We've got a long stretch of flat, powerless conditions ahead, so don't be in a rush to get your board ready.

For the first week and a half or so, we're looking at a whole lot of nothing. The swell is tiny, mostly around 0.7ft to 1ft, and the energy is just about non-existent. It's the kind of surf that'll have you wondering if the ocean is even alive. There are a few glassy moments, like Saturday afternoon, but with next to no waves, it's just a pretty, flat ocean. The water temp is 81°F, about 2°F warmer than average, so it's not a huge deal, but it's noteworthy.

We do see a slight pulse of energy starting on Monday the 17th and into Tuesday the 18th. The swell bumps up to around 2ft, and the energy readings finally pick up. This is a longer period groundswell, 13 to 15 seconds, coming from the west. It's still small, but it's the best we're going to get. The wind on Tuesday morning is offshore from the NW, which will help keep things clean at Kiholo Bay. But honestly, with waves that small, it's still going to be a battle for any decent rides. It's more of a chance to get wet and practice your pop-up than a day to score.

After that, it fades back down into the 1ft range. Thursday the 20th is more of the same, small and weak. The next little blip on the radar comes around Friday the 21st and into Saturday the 22nd. There's another long-period pulse, around 16 to 18 seconds, coming from a south-west direction. The swell height is still small, only 1ft, but the period is long, so it might have a bit more shape. But with a cross-onshore wind, it's not looking great. It's a long way out, so treat this one as promising but not certain.

Honestly, the standout for the whole window, if you can even call it that, is the Tuesday the 18th morning session. It's got the biggest swell, the cleanest wind, and the most consistent energy we'll see. But it's not a day for beginners, and even for the more experienced crew, it's going to be a marginal call. Be patient, keep an eye on the forecasts, and maybe this is a good time to work on your board maintenance.

There are just no good surf options in this 16-day window. It's a flat spell, plain and simple. But this break is usually more consistent than this, so I'd bet the poor run won't last forever. Forecasts can change, so keep hope alive.

Rusty out.

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.

Kiholo Bay is 89 km (55 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
