Advisory cleared at Makaha Beach — Oʻahu coast continues recovering
1 tracked beach cleared DOH advisory status in the last 24 hours: Makaha Beach. Bacteria can linger after visible turbidity clears, so the 72-hour waiting rule still applies if the advisory was rain-driven.
Big Island has been persistently under advisory for 28+ days (no recovery window in the data yet). 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 (+64pp vs. the prior two weeks). 6 of our 6 tracked beaches on the island have active advisory days in the last 30 days. 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 persistently under advisory for 28+ days (no recovery window in the data yet). All 12 of our tracked beaches on the island have had active advisory days in the last 30 days. 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 persistently under advisory for 28+ days (no recovery window in the data yet). All 6 of our tracked beaches on the island have had active advisory days in the last 30 days. NOAA's 7-day forecast is wet (peak 51% chance of rain) — expect the pattern to shift toward more advisories. See the Kauaʻi leaderboard for the beach-by-beach ranking.
