The Lowdown
Alright folks, Rusty here. Let’s not beat around the bush – we’re looking at a pretty grim stretch ahead for Kiholo Bay. The surf is basically a no-show for the better part of two weeks, so don’t get your hopes up. We’ve got a long, flat gap right from the start, with nothing but small wind ripples and glassy but totally flat conditions through the end of July. The water temp is sitting at 80°, which is about average for this time of year, so at least you won’t need a thick suit.
The first real sniff of anything happens around Thursday, July 30th in the afternoon. We get a tiny pulse of 1ft swell from the southwest with a very long period of 18 seconds, and the combined energy is only 64 – weak. That’s a groundswell, but it’s so small it’s barely a ripple. The wind is light cross-onshore from the southwest, so it’s not going to be clean.
Things pick up a tiny bit toward the end of the first week of August. On Friday, August 1st in the afternoon, we finally see a bit of life. The swell bumps up to 2ft from the west, period 12 seconds, and the combined energy hits 137 – still moderate. The wind goes glassy from the WNW, so the surface will be clean. This is the best we’ve got, but it’s still just “surfable waves but very ordinary conditions”. Not a standout by any stretch. For a point break like Kiholo Bay, that long period (12 seconds) is decent, but the size is just too small for any real juice.
Honestly, the whole 16-day window is a dud. There’s one brief moment on the afternoon of August 1st that might be worth a paddle if you’re desperate, but don’t expect much. The rest is flat or near-flat. For a spot that’s fairly exposed to the WNW swell, it’s just a bad run. It tends not to stay this poor forever, but right now, the ocean is taking a nap.
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.
