The Lowdown
Alright folks, Rusty here. Gotta be straight with you; the next couple of weeks are looking pretty flat and uninspiring for Kiholo Bay. There's no real swell to speak of, just tiny dribbles here and there. The water's sitting at 82°, which is a touch warmer than normal for this time of year, so at least a dip will feel nice.
The first good news, or lack thereof, is that we're starting with a gap. There's nothing worth paddling out for right now. Looking at Thursday the 27th, we've got glassy conditions but only 0.7 ft of swell from the north with a short 8-second period. Energy is basically non-existent at (5). It's a no-go.
We string together a few more days of the same story. Friday the 28th and Saturday the 29th offer some glassy windows, but the swell is either nonexistent or just a 0.3 ft to 0.7 ft whisper from the west or southwest. It's heartbreaking because it's dead calm, but there's just no push. This continues right through the end of August and into the first part of September. We're looking at a solid week of flatness with hardly a ripple.
Towards the end of the forecast period, around the 9th of September, we see a slight lift. The swell bumps up to 1.3 ft from the WNW with an 11-second period. The combined energy is still weak at (43), and the wind is a messy cross-onshore from the north at 15 mph. It's still poor surf conditions, and frankly, for a beach and point setup, this looks more interesting for kite surfing than a proper paddle session.
The best of a bad bunch might be the morning of the 11th of September, where we see a 1.3 ft swell from the WNW at a longer 14-second period, giving us a combined energy of (62). The winds are light cross-onshore. It's still tiny, but if you're desperate, you might find a crumbly little wave. But honestly, keep your expectations on the floor.
The whole outlook is a blank run, which is just the way it goes here sometimes. Forecasts can change, but for now, it's a waiting game.

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.
