The Lowdown
Right, let’s have a look at what’s doing at Kiholo Bay. The next 16 days are looking like a real quiet stretch, I’m not gonna lie. There’s a big gap of nothing until Thursday morning the 30th of July, and even then, it’s only just a tickle of a wave.
That first swell shows up on Thursday the 30th. We’re looking at a tiny 1ft groundswell coming from the southwest. The period is a very long 18 seconds, which gives it some real push for its size, but it’s still small. The combined swell energy is weak at 49. The wind Thursday afternoon goes glassy – dead calm – which is beautiful. But honestly, it’s so small it’s more of a chance to float around than really surf.
The rest of the first week and into the first part of August is more of the same. Tiny pulses, weak energy, and mostly cross-onshore winds. There’s a tiny window on Saturday afternoon, the 1st of August, with a 1ft southwest swell and glassy conditions, but it’s a 14-second period (energy of 29) – still very weak. A few mornings and afternoons have glassy conditions on the 2nd, 3rd, and 5th of August, but the swell is either non-existent or a bare whisper.
We finally get a bit more life around Saturday the 8th of August. The morning sees a 2ft west swell with a 13-second period, and the combined energy hits 100, which is just scraping into the moderate category. The wind is offshore from the northwest at 5 km/h. That’s the best on offer across the whole window. Saturday afternoon stays glassy with the same 2ft swell, energy at 84. It’s still small, but it’s the cleanest, most organised wave of the lot. The water temp is about 81°F, which is 1°F above normal, so it’s a touch warmer than average for this time of year.
After that little burst, it fades again. Sunday the 9th and Monday the 10th of August have a bit of 1ft to 2ft west swell, but the wind turns onshore or cross-onshore, messing it up. The rest of the run into the 11th of August is flat and ordinary.
So, if you’re desperate for a paddle, that Saturday the 8th is your best bet. It’s not a standout for size, but the offshore wind and glassy afternoon will make it the cleanest of a very quiet bunch. For beginners, it’s fine; it’s small. For anyone else, it’s a longboard or a SUP day. This is a classic case of a spot that goes quiet for long stretches.

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.
