Advisory cleared at Haleiwa Beach Park — Oʻahu coast continues recovering
1 tracked beach cleared DOH advisory status in the last 24 hours: Haleiwa Beach Park. Bacteria can linger after visible turbidity clears, so the 72-hour waiting rule still applies if the advisory was rain-driven.
Big Island is worsening over the last 14 days (-29pp vs. the prior two weeks). 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 wet (peak 83% chance of rain) — expect the pattern to shift toward more advisories. See the Big Island leaderboard for the beach-by-beach ranking.
