When is high tide?
Hohonu answers the world’s most pressing questions about real-time water-level, starting with the most basic

FREQUENT FLOODING
Flooding Has Become an Urgent Problem
Charleston, South Carolina flooded 89 times in 2019. 4.1 million US homes exist in 100-year floodplains.

NIMBLE DATA COLLECTION,
ENHANCED DATA ANALYSIS
Better Water Level Predictions
Hohonu transforms how coastal communities and property owners measure and respond to rising sea levels, from the local to the global level.
-
Hardware that can be easily installed and maintained along coastlines
-
Proprietary algorithms that enhance existing federal modeling efforts
What We Do?
Hohonu measures and predicts water levels in specific locations for coastal stakeholders and property owners. We provide the sensors and the algorithms to predict future water levels with unprecedented accuracy.

"High resolution data for local coastal conditions do not yet exist at the global scale, preventing world-wide evaluation of Sea Level Rise at local scales."
Who We Are
The Hohonu team is applying emerging engineering technology with its 50+ years of oceanography experience
