The Lowdown
Alright folks, Rusty here again. Let’s talk about Kiholo Bay in the units you might be more familiar with.
It is dead quiet for a long stretch. Starting Thursday the 23rd, we’re looking at a week and a half of flatness. The ocean is like a pond, with no swell at all. You’ll see some glassy afternoons, but with zero waves, that’s just a frustrating sight. A long dry spell through to Wednesday the 29th.
We finally get a tiny pulse on Wednesday the 29th – a 1ft swell from the southwest, but with a period of only 5 seconds and a cross-shore wind. The energy is a measly 3, so it is not worth the drive. More tiny SW pulses follow through the end of July, all under 1ft. The scores are all zeroes and the comments say “poor surf conditions,” so it is what it is.
The one day that breaks the pattern is Friday the 7th of August. In the morning, we see a 3ft swell from the west with a 15-second period. That is a proper long-period groundswell, meaning real energy and shape. The combined swell energy is 302, which is a moderate level. There is a light cross-onshore breeze in the morning, but the afternoon glassed off with a light breeze. The wave comment finally says “surfable waves but very ordinary conditions,” with a score of 1 out of 10. I’m not going to call it pumping, but after this long dry spell, a 3ft west swell with glassy conditions is the best we’ve got. The water temp is about 80°, which is normal for this time of year.
For beginners, the swell is under 4ft, so it’s not too big, but that long period (over 11 seconds) means the wave has more punch and might close out on the beach. Kiholo Bay is a beach and point break, so the point could clean it up a bit. With this quality, crowds will be non-existent.
After the 7th, it fades right back into tiny 0.7ft to 1ft west swells with weak energy. It is a tough outlook overall, but that’s the run we’re in. Forecasts can always change.
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.
