A Vision Rooted in Experience

Haiti sits at the crossroads of some of the most consequential climate forces in the Western Hemisphere, hurricanes born in the warm Atlantic, the oscillating pressures of El Niño and La Niña, unpredictable rainfall patterns that can shift from deluge to drought within a single growing season. Yet for a country where roughly 92 percent of agriculture is rainfed and millions of livelihoods depend on the rhythm of the seasons, Haiti has long lacked the basic infrastructure to monitor its own weather in real time. The consequences of this gap are not abstract. They are measured in failed harvests, in communities blindsided by storms, and in a persistent inability to plan.

Haiti Nexus envisions changing this permanently through the establishment of a comprehensive, island-wide automated weather station network modeled on Florida’s Automated Weather Network (FAWN). Created in 1997 through a partnership between the University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS) and the State of Florida, FAWN now operates over 42 stations from the panhandle to Homestead, collecting data every 15 minutes on temperature, rainfall, humidity, wind speed, solar radiation, soil moisture, and barometric pressure. The network was born from a crisis, a catastrophic freeze in January 1997 that destroyed hundreds of millions of dollars’ worth of crops, and it has since become an indispensable tool for growers, emergency managers, water management districts, and researchers across the state. What FAWN has done for Florida, a Haitian national weather network can do for Haiti, with far greater urgency.

Proven Foundations: The USAID/AREA Weather Station Initiative

This vision is not starting from zero. Through the USAID-funded Feed the Future Haiti AREA (Appui à la Recherche et au Développement Agricole) project, led by the University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS), a foundational network of automated weather stations has already been deployed in Haiti. These stations were originally developed by a team of researchers at the University of Florida, including Professor William Eisenstadt of the Department of Electrical Engineering, and subsequently adapted for the Haitian context by Josue St Fort, PhD, who tailored the systems to operate reliably within the country’s infrastructure constraints.

Beginning in mid-2017, the AREA project installed solar-powered meteorological stations at several strategic locations in and around Port-au-Prince and in the southern peninsula. The stations were placed at Damien, at the FONDHAD site in Croix-des-Bouquets, at the CRRD facility in Montrouis, and at the AUC campus in Les Cayes. An additional station was installed at the Wynne Ecological Farm in Kenscoff, a high-elevation site that provides valuable data from Haiti’s mountainous interior. Each station collects continuous readings on temperature, rainfall, dew point, wind speed, and other parameters critical to agricultural planning, with data automatically uploaded at regular intervals.

Beyond the hardware itself, the AREA project invested heavily in human capacity. Haitian professionals, agricultural researchers, technicians, and meteorologists from institutions including the national Hydrometeorological Unit (UHM), were trained in every aspect of the process: station siting, design, parts procurement, assembly, programming, installation, and troubleshooting. This transfer of knowledge is essential. A sustainable weather network for Haiti cannot depend indefinitely on external technical support; it must be owned and maintained by Haitian professionals.

Confronting the Connectivity Challenge

The pilot deployment revealed important lessons. Chief among them is the challenge of telecommunications connectivity in rural Haiti. In many of the remote agricultural zones where weather data is most urgently needed, the existing mobile networks, primarily Digicel and Natcom provide only 2G or 3G coverage, and even that coverage can be intermittent. Data transmission failures, while not fatal to the stations themselves, create gaps in the real-time data stream that reduce the network’s value for time-sensitive decisions such as irrigation scheduling, frost advisories, or storm preparation.

However, this challenge is eminently solvable. The core issue is not the data collection hardware, which performs well under Haiti’s environmental conditions, but rather the system’s ability to recover and resume transmission after a connectivity interruption. If the stations can be engineered to boot automatically and queue data for transmission once a connection is restored, a capability well within reach with current microcontroller and firmware technology, then intermittent connectivity becomes a manageable inconvenience rather than a structural limitation. Emerging solutions such as LoRaWAN (Long Range Wide Area Network) protocols, satellite-based IoT connectivity, and mesh networking architectures also offer promising pathways for bridging coverage gaps in Haiti’s most remote regions.

Scaling to a National Network: The Haiti Weather Network (HWN)

The goal is ambitious but achievable: a national Haiti Weather Network (HWN) comprising stations distributed across every department, positioned to capture the country’s remarkable climatic diversity, from the arid lowlands of the northwest to the cool highlands of the Massif de la Hotte, from the rain-rich northern coast to the drought-prone Cul-de-Sac plain. A network of this scale would serve multiple critical functions.

For agriculture, real-time weather data would enable growers to make informed decisions about planting windows, irrigation timing, pesticide application, and harvest scheduling. Extension agents and agronomists would have access to localized, current information rather than relying on regional forecasts generated from distant stations or satellite estimates alone. Historical data accumulated over time would reveal trends, allowing researchers and policymakers to develop climate-adapted crop varieties, adjust planting calendars, and design more resilient farming systems.

For disaster preparedness, the network would serve as an early warning backbone. Haiti is struck by tropical storms and hurricanes with devastating regularity. A dense, real-time observation network would dramatically improve the country’s ability to track incoming weather events, issue localized warnings, and coordinate evacuation and relief operations. The data would complement and ground-truth satellite-based forecasts, giving emergency managers a far more accurate picture of conditions on the ground.

An Advanced Climate Advisory System for Haitian Growers

Beyond real-time monitoring, Haiti Nexus proposes building an Advanced Climate Advisory System (ACAS) that translates raw weather data into actionable intelligence for farmers. This system would integrate data from the weather station network with regional and global climate forecasts to provide growers with timely, practical guidance on the threats that shape their livelihoods.

El Niño and La Niña Advisories. The El Niño–Southern Oscillation (ENSO) cycle is one of the most powerful drivers of seasonal weather variability in the Caribbean. El Niño events tend to increase rainfall during Haiti’s dry season months and can alter the timing and intensity of the wet season, while La Niña conditions are associated with a wetter second half of the rainy season and a significantly higher risk of Atlantic hurricanes tracking through the Caribbean. An ACAS for Haiti would monitor ENSO forecasts from NOAA’s Climate Prediction Center and translate them into region-specific advisories: which crops are most at risk, when to plant, when to hold off, what soil and water conservation measures to prioritize. According to the latest NOAA outlook, ENSO-neutral conditions are favored through mid-2026, with a possible transition to El Niño by mid-year, information that Haitian growers need now to plan their coming seasons.

Hurricane and Tropical Storm Preparedness. Haiti’s hurricane season, running from June through November, represents an existential threat to the agricultural sector every year. The advisory system would provide staged alerts — seasonal outlooks in the spring, weekly risk assessments during the active season, and real-time tracking and localized impact projections as storms approach. For growers, this means the difference between losing an entire harvest and having enough lead time to secure crops, protect livestock, and safeguard equipment and seed stores.

Drought Monitoring and Water Management. With precipitation variability projected to increase in the coming decades, drought is an escalating concern for Haitian agriculture. The ACAS would incorporate soil moisture data from the weather stations, satellite-derived vegetation health indices, and the Standardized Precipitation Index (SPI) to provide early drought warnings. Growers would receive practical guidance on water conservation strategies, drought-tolerant crop selection, and supplemental irrigation timing.

Seasonal Planting Calendars. By combining historical weather data with real-time observations and seasonal forecasts, the system would generate dynamic, localized planting calendars, updated annually, that help farmers optimize their planting and harvesting schedules for staple crops like maize, rice, beans, and sorghum. This kind of decision support, grounded in local data rather than national averages, is precisely what Haitian agriculture has lacked.

A Call for Collaboration and Investment

The foundation has been laid. The USAID/AREA project demonstrated that affordable, solar-powered, locally maintained weather stations can operate successfully in Haiti’s challenging environment. The technical expertise exists. The trained Haitian professionals are ready. What is needed now is the commitment, from international development partners, from the Haitian government, from private sector actors, and from the global scientific community to scale this proven model into a national system.

Haiti Nexus is actively seeking collaborators and funding partners to bring the Haiti Weather Network to life. We envision a phased deployment, beginning with the rehabilitation and expansion of the existing AREA stations and progressively extending coverage to every department over a three-to-five-year horizon. The estimated cost of a full national network is a fraction of the annual economic losses Haiti suffers from climate-related agricultural failures, an investment that would pay for itself many times over.

We invite universities, research institutions, international agencies, NGOs, technology companies, and individual donors to join us. Haiti does not lack the intelligence, the will, or the technical capacity to build this system. What it lacks is the resources and the coordinated support to do so. By providing Haiti with its own weather station network and climate advisory system, we are not simply installing equipment, we are equipping a nation to understand, anticipate, and adapt to the climate forces that shape its future.
