Maui water quality is improving (+29pp in 14 days)
Maui ocean water quality improved 29 percentage points over the last 14 days (0% clean two weeks ago vs. 29% clean now).
If the NOAA 7-day outlook stays dry, the improving trend should continue. See the Maui leaderboard for which individual beaches drove the change.
Big Island is worsening over the last 14 days (-21pp 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 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 (+29pp 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 mild — scattered showers possible but unlikely to drive new advisories. See the Kauaʻi leaderboard for the beach-by-beach ranking.
