Hilo, Hilo Bay, Kuhio Bay, HI Daily Water Report — September 1, 2026

Today's water conditions in Hilo are a mixed bag, but there's something for everyone if you time it right. Divers and anglers will find the best conditions with both scoring a solid 8.1 out of 10. The calmest waters around 7 PM make for an ideal diving window, while fishing enthusiasts should aim for the solunar major periods early in the morning or mid-afternoon. Surfers will enjoy a pretty good day with a 7.8 out of 10, thanks to consistent wave heights around 2 meters and a swell coming from 62 degrees. The wind is manageable, peaking at 17.5 knots by late afternoon, which may add a bit of challenge but also excitement for experienced surfers. Meanwhile, sailors face a less thrilling day with a 5.3 out of 10, as the wind conditions are somewhat inconsistent. The boating and kayaking scores are middling at 5.8 and 5.6 respectively, largely due to the wave height and a persistent low cloud cover. It's not the best day for these activities, but if you're set on it, aim for the early morning or late evening when the winds are lighter. Today's atmospheric conditions are a bit murky, with visibility at a mere 0.54 km due to the high humidity and dense cloud cover. This isn't ideal for wildlife watchers, but the solunar periods might still offer some interesting sights if you’re patient. Looking ahead, expect more rain and similar wave conditions through the week, with a significant chance of precipitation every day. If you’re planning a water adventure, tomorrow’s forecast suggests a slight increase in wave height, which might spice things up for surfers. For today's best bet, gear up for a dive just before sunset when the waves are at their calmest and the water temperature is a comfortable 27°C, promising a serene underwater experience.
