The Lowdown
Alright partners, Rusty here, let’s talk about the Kona coast.
Right now, it’s looking pretty sad for the next week and a half. From Wednesday the 29th of July through the first week of August, the waves are tiny. We’re talking 1 to 3 feet of swell, mostly junk. The wind is either cross-onshore or straight onshore, so it’s chopped up and messy. The wave energy is weak, mostly in the 1 to 234 range, so nothing’s pushing. On the 2nd of August, there’s a 3-foot NNE swell, but with a period of only 7 seconds, it’s just a bumpy mess. Not worth it.
Water temp is 81°, which is about 1° warmer than average for this time of year – a touch warm, but nothing unusual.
The first real light shows up on Saturday the 8th of August. That afternoon, we see a 2-foot SSW swell with a 19-second period and combined energy of 578 (moderate). The wind is onshore from the west, so it’s still marginal. Sunday the 9th of August morning is similar – 3-foot SSW swell, 17-second period, and energy of 585 (moderate). The wind goes glassy-light from the WSW. That’s the first time it’s clean, but it’s still marginal.
Then Monday the 10th of August is the best day. The morning brings a 4-foot SSW swell with a 16-second period and combined energy of 944 (moderate-to-strong). The wind is a light cross-onshore from the WSW. The afternoon stays at 4 feet, SSW, 15-second period, with energy of 913 (moderate-to-strong). This is the standout. The swell direction is SSW, which works well for Honokohau Harbour’s optimum from the WNW, so it’ll wrap in nicely. This is a consistent reef break, and it’s an intermediate spot. Crowds are sometimes around, so expect a few guys out. The wind is light, so the waves will be clean.
After that, the 11th and 12th of August drop back to 2 to 3 feet, and the energy fades. By the 13th, it’s back to 2 feet and weak. So, Monday the 10th is your best shot. Don’t sleep on it.
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.
