PacIOOS
Wave Run-Up Forecast:  West Maui

The PacIOOS Wave Run-Up Forecast is a tool to predict the potential occurrence of high sea levels and wave inundation impacting the shorelines of West Maui to increase community resilience and enhance preparedness by providing time to plan and respond in advance of potential flooding events.

Data Trends in Water Quality and Percent Live Coral Cover

Hui O Ka Wai Ola data through Dec.2023 showing geomeans for nitrate nitrite nitrogen (green bars) and turbidity (water clarity) in brown relative to the Hawaii Department of Health state standards shown in the dashed red lines.  Sites go from the north at Honolua Bay to the Pali in the south.
Hui O Ka Wai Ola collects data for ocean salinity, pH, temperature, organic nutrients (nitrogen and phosphorous compounds), dissolved oxygen (DO), and turbidity. Some water samples are immediately tested at mobile labs, while others are processed for testing at University of Hawaiʻi.

Commision of Water Resource Management (CWRM) Streamflow

In recent years, CWRM has installed additional stream gauges in West Maui (and beyond) to help determine flow, and in some areas, turbidity.  This data is now available through this data portal.
