Kahului Harbor Surf Forecast and Surf Report

Alright, Rusty here, and I gotta be straight with you. I’ve been through the numbers for the next 16 days, and I’ll tell you right now, for Kahului Harbor, it’s a tough watch. The whole 16-day run is basically a blank—no good surf options at all. Every single session is flagged as poor or marginal. You’re looking at a lot of cross-shore and cross-onshore winds, mostly from the ENE, kicking up choppy, lumpy conditions. The swell is there, but it’s short-period, messy, and never lines up right.

The water temp is sitting right around average for the time of year, so nothing weird there. But the pattern is grim. From Saturday the 1st of August right through to Sunday the 16th of August, there’s just nothing to get excited about. The first few days, you’ve got a 7 ft ENE swell coming in at 8 seconds, but with 25 km/h cross-winds, it’s a chop-fest, and the combined energy is moderate (818). That’s the best of a bad bunch, and it’s still not worth paddling out for.

By the 2nd and 3rd, the swell drops to 5 ft to 7 ft, but the wind stays onshore and choppy. The energy stays moderate (694–424), but the quality is zero. Midweek, from the 5th onwards, the swell shrinks to 3 ft or less, period drops to 7–9 seconds, and the energy dips into the weak range (down to 130). There’s a tiny bump on the 13th with a 5 ft swell and period 8 seconds, but again, cross-shore wind and poor conditions. The last day, the 16th, has a small 2 ft WNW swell with a longer period of 13 seconds, but it’s cross-onshore and choppy—kite surfers might be into it, but for a paddle surfer, it’s a no-go.

For a spot that’s consistent and exposed to NNE swell, this is a real dry spell. But forecasts can turn, so don’t write it off completely. For now, save your energy.

Rusty.
