Stop Guessing
Start Acting
From Sensors to Strategy
Rugged hardware, real-time dashboards, integrations, and advanced analytics - giving governments, consultants, and communities the confidence to prepare, respond, and recover.
Robust, Easy to Install Sensors
Low-cost ultrasonic and radar technologies for daily and extreme event monitoring over water or over land.
Public Live Maps
Real-time, public dashboard and mobile app that keep communities informed and build trust.
Seamless Workflow Integrations
​Directly connect with NWS, ArcGIS/ESRI, and other systems—or embed live data on your own website with just a line of code.
Strategic Planning & Response
An expanding suite of tools - from threshold analyses to forecast calendars - to enable confident decision-making
Suite of Robust Sensors
Flood sensors that anyone can install - filling the gaps NOAA and USGS networks miss.
No
Maintenance
Solar-powered and low-maintenance — no external wiring required.
Scientific
Rigor
Validated against federal gauges for defensible, compliance-ready data.
Anywhere Flooding Happens
Flexible design proven to withstand harsh conditions that NOAA and USGS networks can’t reach.
Public Live Maps
Transparency that builds trust. Live maps that combine real-time sensor data with forecasts, including the only iOS app with live tidal data.
Web & Mobile Access
Responsive web dashboards plus a dedicated iOS app — the only app in the App Store with live water level data, not just predictions.
Multi-Source Data
View real-time and historical measurements from Hohonu sensors alongside NOAA and USGS data — all in one dashboard.
Every Type of Flood Coverage
Monitor tidal flooding, urban inundation, and river levels from a single platform.
Opt-In Community Alerts
Anyone can sign up for text messages — instant alerts when flooding begins and advance notice of king tides up to 7 days ahead.
Storm Tracking
Overlay live storm systems with real-time sensor data for clearer situational awareness.
Seamless Workflow Integrations
Your Systems + Hohonu's Data. Connected. The Hohonu Platform is designed to fit into the tools and workflows you already use.
API-Ready for
Any System
Plug directly into ArcGIS, ESRI, DOT, and emergency management systems with secure APIs.
Public
Website Embeds
Share live data with residents and stakeholders — just one line of code to publish a real-time map.
Quality-Checked
Data Streams
Every data feed is continuously monitored and validated for defensible information you can stand behind.
Example From The Field
The National Weather Service integrates dozens of Hohonu data into its Water Prediction Service across the entire state of Florida
Strategic Planning & Response
From monitoring to actionable intelligence. Hohonu goes beyond real-time data, equipping decision-makers with tools to prepare, act, and recover.
Threshold Alerts
Configurable alerts that trigger when water reaches critical levels — supporting road closures, asset protection, and faster response.
Post-Event Hindcasts
Historical reconstructions of flood events provide validation for projects, funding requests, and resilience planning.
Forecast Calendars
King tide forecasts and calendars available in advance to help agencies plan resources and engage communities.
Custom Analyses
For complex scenarios, our team works with partners to deliver one-off studies and analytics tailored to specific planning needs.
