Hilo, Hilo Bay, Kuhio Bay, HI Daily Water Report — August 29, 2026
Today in Hilo Bay, diving takes the spotlight with a score of 8.2 out of 10, thanks to favorable conditions including gentle winds and warm water temperatures. If you're planning to dive, the calmest sea state will be just after midnight, with waves dipping to 1.54 meters. The water temperature is a balmy 27.9°C, perfect for a long dive. Surfing is also a good bet today with a score of 7.5 out of 10, consistent with recent days. The swell is coming in from 72 degrees at 1.44 meters with a period of 5.1 seconds.

The full moon is almost at its peak, providing strong solunar activity in the early morning and around noon. Despite the low chlorophyll levels indicating less productivity, the solunar factors and calm winds should offer decent fishing windows. Boaters and kayakers will find the conditions moderately suitable with scores of 6.5 out of 10. Although the wind is light, gusts could reach up to 15.9 knots around noon, so plan accordingly. Visibility is decent at nearly 13 kilometers, but keep an eye on the persistent light rain throughout the day. Sailors might find today less favorable, scoring just 4.6 out of 10, as the inconsistent wind and cloud cover don't quite cooperate for optimal sailing conditions. Looking ahead, expect similar wave conditions but increasing chances of rain, particularly from August 31st onward. Waves will gradually build, potentially reaching 2.1 meters by September 3rd. If you’re seeking a memorable experience today, diving is the standout choice with its combination of warm waters and excellent visibility.
