Kahului, Kahului Harbor, HI Daily Water Report — September 1, 2026

Today is a fantastic day to hit the water in Kahului Harbor, especially if you're looking to sail or dive. With a stellar sailing suitability score of 9.2/10 and diving at 9.3/10, the conditions are nearly perfect for these activities. The consistent ENE winds, blowing at a steady 10 knots and gusting up to 19, provide a thrilling yet manageable challenge for sailors. Meanwhile, divers will appreciate the calm seas with wave heights peaking at just 0.8 meters, ensuring excellent underwater visibility in the oligotrophic blue waters. For those planning to fish, the score is a solid 8.1/10. The solunar periods around dawn and late afternoon promise the best action, but be prepared for the occasional gust and a slight drop in barometric pressure, which might keep the fish on their toes. Surfing is also looking good at 8/10, with the long swell period of 11.75 seconds offering some smooth rides, though not quite as energetic as earlier in the week. Kayakers might find today a bit of a mixed bag, with a score of 5.8/10. The wind and slight ocean current could make paddling more strenuous than usual, so it's best to stick close to shore. Boaters, with a score of 7.7/10, should watch for the stronger gusts expected around 2 PM but will otherwise enjoy a pleasant day on the water. Looking ahead, the conditions are set to change with increasing wave heights over the next few days, peaking at 1.2 meters by September 7. Rain chances are fluctuating, so keep an eye on the forecast as you plan your activities. For a memorable experience today, seize the opportunity to dive in these pristine conditions—it's a marine world waiting to be explored.
