The Lowdown
Alright folks, Rusty here. Let's take a look at what's on the menu for Kiholo Bay. It's been flat or close to it for a good long while, and the first thing I gotta tell you is that this stretch of the forecast is a quiet one. There's a big gap of no-go days from the start, all the way through the 29th of July. We're talking about a week of nothing but small wind ripples and cross-shore chop, so don't even bother waxing up until we get to the end of the month.
The first real sign of life shows up on Thursday morning, the 30th of July. A tiny, long-period 1ft swell from the SW with a period of 18 seconds creeps in, but the combined energy is weak (49) and the wind is onshore. It's not worth paddling out for. That same pattern holds through the 31st into the 1st of August – tiny, inconsistent energy with less than ideal wind.
Now, things start to look a little more interesting come the 6th of August. On Thursday the 6th, we get a 1ft WNW swell with a period of 14 seconds, and the wind goes glassy in the morning. That's a clean window, but the combined energy is still low (37). The water is sitting at 81°, which is about 1° warmer than average for this time of year, so pretty normal really.
The standout, and I mean the only real window to get excited about, is the afternoon of Saturday the 8th of August. We see a 2ft swell from the west with a 16-second period. The combined energy jumps to 168 (moderate), and the wind is glassy. That's clean, calm conditions. The ideal swell direction for this spot is from the WNW, so this is right on the money. It's a consistent break, so you know it'll be working, but it's not a big wave – fine for an intermediate, not going to scare anyone. Because it's a consistent spot, crowds are possible, so don't expect to have it completely to yourself. This is your best bet by a long shot.
The following day, Sunday the 9th, has a slightly bigger 3ft W swell with a 16-second period, and the energy is up to 339, but the wind is cross-onshore. It's a step up in power but the conditions are rougher. Then Monday the 10th of August, the afternoon shows a 3ft W swell, 15-second period, with glassy conditions and combined energy of 347. That's a solid, clean option, but it's a week and a half out, so keep an eye on it.
Overall, the second week is where the hope is. The 8th of August afternoon is the pick of the litter. The rest of the time is a waiting game.
Stay patient.
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.
