How Hohonu Is Helping Hawaii Use AI to Protect Coastlines, Harbors, and Communities From Rising Seas
Hohonu is a Hawaii-based ocean technology company that deploys a network of low-cost, solar-powered water level sensors along coastlines, harbors, and estuaries, and uses AI to turn that real-time data into predictive flood and surge alerts. The platform gives coastal managers, emergency planners, and harbor operators granular, localized sea level intelligence that national buoy networks — built for navigational purposes — simply do not provide. Hohonu's AI processes sensor data alongside weather models and historical tide patterns to generate site-specific forecasts of coastal flooding risk. The system sends automated alerts when conditions cross user-defined thresholds, giving port operators, road managers, and emergency coordinators advance warning they can act on — hours before a tidal surge, storm event, or king tide creates dangerous conditions. Hawaii's geography makes coastal monitoring uniquely critical: the state has hundreds of miles of low-lying coastline, major harbors that are linchpins of the supply chain, and communities directly exposed to sea-level rise and Pacific storm surge. Hohonu was built for this environment and has deployed sensors across harbors, beaches, and drainage infrastructure throughout the islands. Hohonu is a compelling example of AI infrastructure that protects physical infrastructure — and the communities that depend on it. For Hawaii's coastal management agencies, port authorities, and emergency management offices, the value proposition is straightforward: better data, earlier warnings, and fewer surprises from the ocean that surrounds every community in the state.
