The Lowdown
G’day, Rusty here. Let’s break down what’s happening at Honokohau Harbour. This reef break is consistent and likes swell from the WNW, and the water temp is about average for the season.
The first few days are a rough start. Thursday the 3rd and Friday the 4th are tiny, with weak energy (65–93) and crummy cross-onshore winds. Not worth your time. Saturday the 5th picks up to 1.6m from the SSW, period 12 seconds, but the wind is cross-onshore, and the energy is moderate (762). It’s surfable, but messy. Sunday the 6th and Monday the 7th see a big jump – 2.2m to 3.0m from the SW, periods 13–14 seconds, and energy in the strong range (1585–3785). Winds are still cross-onshore or onshore, so it’s lumpy. Over 2.5m is for experts only, and this is a reef, so it’s serious.
The standout is Monday afternoon (7th). Swell hits 4.5m from the SW, period 14 seconds, and the energy is massive at 9540. Wind is a gentle cross-shore, the best we’ll see. That’s raw power for the experienced crew. Beginners shouldn’t even think about it.
From Tuesday the 8th, it fades. Swell drops to 2.0m or less, winds become moderate cross-shore and choppy. There’s a small window on Wednesday the 16th morning – glassy, 1.0m from the SW, 18-second period, and solid energy (789). That’s a clean session if it holds, but it’s far out and less certain.
Best bet: Monday the 7th afternoon for experts. The mid-week of the 16th for a cleaner, smaller session. Rest of the 16 days is small, weak, or blown out. Crowds are possible on the good days.

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.
