Kahului, Kahului Harbor, HI Daily Water Report — August 30, 2026

Today’s conditions at Kahului Harbor are looking promising for a variety of activities, with sailing and boating taking the top scores. Sailing enthusiasts will enjoy an 8.5/10 day, thanks to steady ENE winds ranging from 8.1 to 18.5 knots and minimal cloud cover. Boaters can expect an 8.2/10 experience, with the same favorable winds and manageable waves peaking at around 0.8 meters. For surfers, today’s 7.9/10 conditions are decent, with consistent swells of 0.66 meters at 10.25 seconds from the south. While not the most epic surf day, the gentle conditions provide a good opportunity for those looking to catch some waves without the intensity. Fishing scores a respectable 7.4/10, with solunar activity peaking during the early afternoon and a high tide at 15:34, which might lure in some good catches. Kayakers should note a slightly lower score of 6.9/10, likely due to the gusty winds, which could reach up to 35.6 knots around 13:00. These conditions require a bit more skill and caution, especially for those less experienced. Unfortunately, diving enthusiasts might be disappointed with the lack of a clear score, suggesting conditions might not be ideal underwater today. Compared to the past few days, today offers a slight improvement for fishing and kayaking, though diving conditions have notably declined from previous scores above 9/10. Looking ahead, expect similar wave heights with an increased chance of rain and slightly cooler temperatures over the coming days. The best bet today? Get out on the water with a sailboat or a sturdy motorboat before the afternoon gusts kick in for a smooth, breezy adventure.
