The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right off the bat, I’ve got to be straight with you – this is a quiet stretch. The first real chance of a wave comes Saturday afternoon, July 18th, at Kiholo Bay. It’s a tiny little knee-high swell, 2ft from the west, with a nice long period of 13 seconds. That’s a proper groundswell, so it’ll have some shape to it, but the energy is weak – only 87 (combined energy). The water’s sitting at 80°, which is about 1° warmer than average for this time of year, so nothing unusual. The wind is glassy, coming from the north at 3 mph, so it’ll be clean. The break is a beach and point setup, a bit exposed to the WNW, and the guidance says it handles a WNW swell well. This is the best on offer, but it’s a real mellow session for intermediates. It’s a consistent spot, but crowds are possible as it’s the only show in town.
After that, Sunday morning, July 19th, has a tiny 1ft swell from the WNW with glassy conditions, but the rating is a zero – it’s just too small. The rest of the week from Monday the 20th onwards is a write-off. There’s a long, dry gap from Monday morning through to Thursday morning, July 30th, with nothing but zeros and flat spells. The combined energy reading is zero for most of those days.
Things try to pick up again on Thursday afternoon, July 30th, with a 1.0ft swell from the southwest and a very long period of 18 seconds. That’s a serious groundswell, but the size is tiny. The energy is only 49 (combined energy), so it’s weak. The wind is glassy, so it’ll be clean, but the swell is barely there. The rating is still a zero, meaning it’s not really surfable. Friday, July 31st, and Saturday, August 1st, are also poor, with tiny, weak 0.7ft to 1.0ft swells.
The biggest pulse of the run shows up on Sunday, August 2nd. The morning has a 1ft swell from the west at 15 seconds, and the afternoon bumps up to 2ft from the west at 14 seconds. The combined energy hits 116 in the morning and 173 in the afternoon – that’s moderate energy, finally. But it’s still small, and the wind is cross-on from the west at 3 to 6 mph, which puts a bit of a crinkle on the surface. The rating is still a zero, so even that isn’t considered good. For a stronger wave over knee-high, it’s too small and the wind is messy.
Honestly, this is a bleak run. The only window that’s even worth a mention is that Saturday afternoon, July 18th, with the tiny, clean 2ft west swell. After that, you’re looking at a solid two-week gap of nothing worthwhile. The spot is consistent, but the ocean just isn’t playing ball. It tends not to stay this poor for long, but right now, it’s a waiting game.
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.
