The Lowdown

Alright folks, Rusty here. Let’s have a look at what Kiholo Bay’s got cooking for us for the next couple of weeks, and I gotta be straight with you – the pickup’s real slim for paddle surfing. The whole run looks like it’s gonna be a quiet one, with only a tiny window of anything rideable, and even then it’s pretty average.

The first sniff of any action shows up Monday, September 7th. Morning starts off clean with light offshore wind from the WNW, but the swell’s a weak 3 feet from the SW (energy around 205). That’s small and wobbly, not worth getting excited over, and conditions are labelled poor. The afternoon does bump up a touch to 4 feet from the SW, but with a very long 14-second period, it’ll be fat and lazy at this beach and point setup. Combine that with marginal tide conditions and you’re looking at a bit of a struggle for a wave. Not your day.

Tuesday the 8th sees a pulse of bigger swell – 6 feet from the WSW in the morning (energy of 638, moderate) and 5 feet in the afternoon – but the wind swings cross-shore and the quality is shot. It’s messy, poor surf. If you’re a kite surfer, that onshore chop might be fun, but for a paddle board, you’re fighting the bumps. Not recommended.

After that, it’s a long, dusty stretch. From Wednesday the 9th all the way through to the end of the forecast, we’re looking at tiny waves, mostly under 2 feet, with onshore or cross-onshore breezes. The energy figures are mostly single digits or just over 100 a couple of times – that’s barely a ripple. The water temperature is about average for this time of year.

There’s one really strange little blip on Thursday the 10th, late afternoon. We get glassy conditions with a 1 foot groundswell from the SW at a massive 18-second period. The energy is only 70 – that’s weak. It’s a pretty sight, but with that tiny size and that sort of long period at a beach and point, it’s gonna break straight and require a glassy surface just to feel a lump. Not a surfer’s wave, more of a swim.

The standout in this entire 16-day outlook is basically none. There’s no moment that truly offers good, clean surfable waves. The only half-decent-looking period is the afternoon of Monday the 7th, and that’s still a marginal call at best with a long period and questionable tide. The rest of the fortnight is dominated by zeros and poor conditions. If you absolutely have to get wet, that Monday afternoon is your best bet for something, but keep your expectations real low – it’s a long wait.

Keep the board waxed and hope the forecasts change. We’re in a dry spell, and these blank runs are just part of the rhythm here.

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.

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.
