Hilo, Hilo Bay, Kuhio Bay, HI Daily Water Report — September 3, 2026

Today's conditions in Hilo offer a solid window for surfers and divers, with surfing scoring 7.8/10 and diving close behind at 7.7/10. Surfing enthusiasts will appreciate the 2.32-meter waves rolling in with a period of 8.25 seconds, complemented by a gentle westerly breeze at 4 knots. Divers can enjoy the warm seas at 27.7°C, though visibility might be slightly challenged by the 84% cloud cover. Fishing scores a decent 6.5/10, but it's a tad lower than the past few days where it hovered in the 7.6-8.3 range. The solunar major periods around dawn and dusk could still yield some rewarding catches, so timing your trip to these windows might pay off. Boaters and kayakers should proceed with caution due to the moderate waves and a current moving northward at 0.6 m/s. The scores here—5.7/10 for boating and 5.3/10 for kayaking—reflect the conditions that aren't as favorable as earlier in the week when boating touched 7/10. The strongest winds are expected around 13:00, gusting up to nearly 20 knots, so plan accordingly. Sailing conditions are less than ideal at 4.4/10, primarily due to inconsistent winds and substantial cloud cover. If you're set on setting sail, aim for the early afternoon when winds pick up slightly. Looking ahead, the weather remains fairly stable, but expect a slight drop in wave height over the next week. By September 8th, waves could reduce to as low as 1.5 meters, making it a potentially better day for boating and kayaking. For today, surfers and divers have the best of it. Grab your board or dive gear and make the most of the conditions before the weather shifts in the coming days.
