Welcome to the mobile version of PacIOOS Voyager. Map and access real-time ocean observations, forecasts, and related information.
The Pacific Islands Ocean Observing System (PacIOOS) is one of 11 regional associations in the U.S. Integrated Ocean Observing System (IOOS) and spans the whole of U.S. interests in the insular Pacific region. IOOS provides timely, reliable, and accurate ocean information to support a safe, clean, productive ocean and resilient coastal zone.
We value your feedback. Please contact us with any questions or suggestions.

Directly measured with instruments:
caution: One of the limitations of all available and EPA-approved test methods is that the water sample must be incubated for about 24 hours. As a result, an alert status may or may not be reflective of actual water quality because it is based on tests performed one or more days ago.
Nearshore: This describes the beach and nearshore conditions. This information is important to beach goers, swimmers, snorkelers and surfers.
Offshore: This describes the offshore conditions. This information is important for kayakers and boaters.
Ratings are updated daily at 9am, 3pm, and 7pm or as conditions change. To have the safest experience, visit guarded beaches with a normal caution rating (yellow square).
Directly measured with instruments:
This shows the movements of several cetaceans (whales and dolphins) who were fitted with satellite tags near Kona off the west coast of Big Island. This intermittently tracks their locations over time as the cetaceans breach the water's surface.
Caution: Cetaceans can move substantially since their most recently reported positions. Geolocation estimates from the Argos satellite can be off by a mile or more.

This flood map shows the 100-year and 500-year flood plains as they appear on the Federal Emergency Management Agency's (FEMA) adopted Flood Insurance Rate Maps (FIRMs) now in effect. Evacuate flood hazard areas in times of impending flood.
Directly measured with instruments:
Rain Gauges: Provides accumulated rainfall totals at about 20 locations across Hawaiʻi.
Stream Gauges: Measures stream height and discharge at about 60 locations across Hawaiʻi.
Data are updated at 15 minute intervals.
Computer-generated predictions:
caution: These forecasts are experimental and no promise of accuracy is implied; especially, the forecasts are explicitly not accurate when either a tsunami, tropical storm, or hurricane warning is in effect.

This shows the movements of several tiger sharks who were fitted with satellite tags near Maui and Oʻahu. This intermittently tracks their locations over time as the sharks breach the water's surface.
Caution: Sharks can move substantially since their most recently reported positions. Geolocation estimates from the Argos satellite can be off by a mile or more. There are many more sharks in the ocean than those tagged for this project.

If you are in a low-lying area near the coast or in the tsunami evacuation zone during a significant earthquake, get to higher ground outside of the evacuation zone immediately. A locally-generated tsunami could reach the shore within minutes, even before a warning can be issued. The Hawaiian Islands are also vulnerable to Pacific-wide tsunamis: these result from distant earthquakes or landslides in places like Chile, Alaska, and Japan and can arrive in Hawaiian waters within hours.
Directly measured with instruments:
Turbidity is a measure of water clarity, the degree to which light entering a column of water is scattered by suspended solids. Suspended solids include things such as mud, algae, plant/animal material, and fecal matter. Factors contributing to water turbidity include soil erosion, elevated nutrient inputs, and waste discharge.
