The Lowdown
Alright, folks, Rusty here. Let’s talk about what’s on the table for the Kona coast window, specifically Honokohau Harbour. The word is, we’ve got a bit of a slow start, but there’s a chance for a couple of sneaky fun sessions if you’ve got the patience.
The water’s running at about 80°, which is pretty much normal for this time of year at Honokohau Harbour, so no surprises there.
The first few days are a bit of a write-off, honestly. Tuesday morning, the 21st, there’s a bit of a long-period groundswell from the SW at 1 ft but with a 17-second period and cross-on wind, the 91 (weak) combined energy just isn’t there to make it worthwhile. The wind is a light cross-onshore, so it’s bumpy and small. That afternoon isn’t any better, with a similar setup and no real punch. Wednesday the 22nd is even smaller, with a choppy wind shift and energy dropping to 35 (weak) – it’s a skip.
The first real glimmer of hope shows up on Thursday afternoon, the 23rd. The swell bumps up to 3 ft from the SSW, with a moderate 20-second period, and the combined energy jumps to 723 (moderate). The wind is a light cross-onshore, so it’s not perfect, but it’s worth a look if you’re frothing for a little reef session. Friday afternoon, the 24th, is the standout. The wave height is 3 ft, still from the SSW, but the wind drops to a glassy 3 mph. The energy is 501 (moderate) and the surface is clean. This is the best window in the whole outlook – a proper glass-off session on the reef. It’s a consistent spot, but crowds can happen, so be ready to share if you paddle out then.
After that, things settle back into the marginal zone. Saturday the 25th has a bit more size, up to 4 ft from the SSW on Saturday afternoon, with 883 (moderate) energy, but the wind is a light cross-onshore again. It’s ridable, but not as clean as Friday. By Sunday the 26th through to the end of the month, we’re looking at little bumps of 2 ft to 3 ft, but the energy drops off and the wind stays mostly cross-onshore. Nothing to get excited about.
Into the first week of August, the swell tries to pick up again. On Saturday the 1st, there’s a pulse of 4 ft from the NNE in the afternoon, but the period is a short 7 seconds, which makes for a weak, wonky wave. The energy is 340 (moderate), but the short period kills it. Sunday the 2nd has a bit more size, 4 ft to 5 ft from the NNE, but with a 6-second period and onshore wind, it’s just messy. Not worth paddling for.
The rest of the run into the 5th of August is small, weak, and mostly poor. The spot is consistent, so it’s a bit of a bummer to see such a flat spell, but that’s the way it goes sometimes. The one real standout is that Friday afternoon, the 24th – if you can get on it, that’s the session to chase.
Rusty.

Information about the Honokohau Harbour Surf forecast
The above surf forecast table for Honokohau Harbour provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Honokohau Harbour can be found by selecting the local surf guide option on the grey menu. Our Honokohau Harbour 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 (Honokohau Harbour) 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 Honokohau Harbour 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.
Honokohau Harbour is 99 km (61 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.
