Hawaii Water Quality — May 6, 2026

Big Island has been mostly advisory-affected across both 14-day island-wide advisory-day windows. Our 7 tracked beaches happen not to overlap with the DOH advisories driving this signal — the worsening trend is from island-wide or other-area advisory events. NOAA's 7-day forecast is dry, which should halt new advisory activity and let the existing advisories begin to clear. See the Big Island leaderboard for the beach-by-beach ranking.

Maui is improving over the last 14 days (+100pp vs. the prior two weeks). 1 of our 6 tracked beaches on the island recorded one or more advisory days in that 30-day history window. NOAA's 7-day forecast is dry, so the improving trend should continue. See the Maui leaderboard for the beach-by-beach ranking.

Oʻahu has been mostly advisory-affected across both 14-day island-wide advisory-day windows. All 12 of our tracked beaches on the island recorded one or more advisory days in that 30-day history window. NOAA's 7-day forecast is mild — scattered showers possible but unlikely to drive new advisories. See the Oʻahu leaderboard for the beach-by-beach ranking.

Kauaʻi has been mostly advisory-affected across both 14-day island-wide advisory-day windows. All 6 of our tracked beaches on the island recorded one or more advisory days in that 30-day history window. NOAA's 7-day forecast is mild — scattered showers possible but unlikely to drive new advisories. See the Kauaʻi leaderboard for the beach-by-beach ranking.
