The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the menu for the next couple of weeks.
Honestly, it’s a tough stretch. We’re looking at a long, dry spell with no real surf to speak of for the better part of the next two weeks. The first recommendation for a wave doesn’t show up until Thursday morning, the 30th of July, and even then it’s barely a ripple. There’s a gap of several days at the start with nothing worth paddling out for.
The first sign of life comes early on Thursday the 30th of July, but it’s fleeting. The morning is glassy and clean, but with no swell. By the afternoon, a tiny 1 ft groundswell from the southwest bumps the combined energy to a weak 49 (49). The period is a very long 18 seconds, which is great for shape, but at that size, it’s not going to do much. The wind shifts to a light cross-onshore, so it’s not pristine.
Friday the 31st of July sees a similar story. We’ve got that same weak 1 ft SW groundswell, with periods dropping from 16 to 15 seconds. The energy is still weak, ranging from 50 to 54 (50-54). Winds are light cross-onshore from the north, so it’s messy for what little there is.
The rest of the first week and into the second week is a total bust. Tiny, short-period windswells and onshore winds dominate. The water temperature is sitting at 80°, which is about 1° above average, so nothing unusual there, but it won’t help you get a wave.
Now, right at the very tail end of the 16-day window, we get a little glimmer. On Sunday the 9th of August, the morning shows a 2 ft west swell with a period of 14 seconds, pushing the combined energy into a moderate 104 (104). The wind is light and variable, but it’s onshore. The afternoon sees a slightly smaller 1 ft swell from the west-northwest, but with a longer 15-second period and energy of 119 (119). The wind is light cross-onshore. This is the best looking window, but it’s a long way out, so treat it as promising but not locked in.
For the standout, if you’re desperate, keep an eye on Kiholo Bay for the first week of August. The best chance is that Sunday the 9th, but it’s for experts only given the lack of power. The west-northwest swell direction is a good match for the spot’s optimum, but with the small size and onshore winds, it’s not going to be a classic. Crowds are a possibility at Kiholo Bay, but with this forecast, it might be quiet.
To be honest, the whole setup looks more interesting for a kite session than a paddle session, if the wind picks up.
Rusty, signing off.

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.
