SENAMHI is the national meteorological and hydrological service of Peru, responsible for observing, analyzing, and forecasting atmospheric and hydrological conditions across the Peruvian territory. It provides climatological records, early warning information, and technical support for sectors such as agriculture, aviation, and water resources. The agency interacts with regional and international bodies to coordinate disaster risk reduction, climate services, and scientific research.
SENAMHI traces institutional roots to early 20th-century efforts when meteorological observations in Lima, Arequipa, and Cusco were recorded alongside activities of the Aeronautical Corps of Peru, International Meteorological Organization, and later the World Meteorological Organization. Formal consolidation occurred under Peruvian legislation in the late 1960s, influenced by models from the United States Weather Bureau, Servicio Meteorológico Nacional (Argentina), and Instituto Nacional de Meteorología e Hidrología (Colombia). During the 1980s and 1990s SENAMHI expanded observational sites following hydrological crises linked to the 1982–83 El Niño event and coordination with the Pan American Health Organization, Food and Agriculture Organization, and United Nations Development Programme for capacity building. The 21st century saw modernization projects supported by the Inter-American Development Bank, World Bank, and technical cooperation from National Oceanic and Atmospheric Administration, European Centre for Medium-Range Weather Forecasts, and Servicio Meteorológico Nacional (Spain).
SENAMHI is organized into technical directorates and regional offices distributed along Peru’s coastal, Andean, and Amazonian zones, interacting with ministries such as the Ministry of Environment (Peru), Ministry of Agriculture and Irrigation (Peru), and Ministry of Transport and Communications (Peru). Key units include directorates for meteorology, hydrology, climatology, and forecasting, with specialized laboratories cooperating with universities like the National University of San Marcos, Universidad Nacional Agraria La Molina, and Pontifical Catholic University of Peru. Regional delegations collaborate with local governments including the Regional Government of Lima, Regional Government of Cusco, and Regional Government of Loreto for subnational monitoring. Administrative oversight and budgeting have involved parliamentary scrutiny from the Congress of the Republic of Peru and audits by the Comptroller General of the Republic.
SENAMHI issues weather forecasts, hydrological bulletins, climate normals, and early warnings for phenomena such as floods, droughts, and frost affecting sectors represented by the Peruvian Air Force, Comisión Nacional para el Desarrollo y Vida sin Drogas, and the Peruvian Society of Environmental Law. Services include aviation meteorological support for airports like Jorge Chávez International Airport, marine forecasts for ports including Callao, and agroclimatic advisories for regions such as La Libertad, Arequipa, and Piura. It maintains climatological archives used by researchers at institutions like the International Research Institute for Climate and Society, CIMMYT, and Centro Internacional de Agricultura Tropical. Public products are disseminated via collaborations with broadcasters such as Panamericana Televisión, Canal N, and the national press like El Comercio and La República.
The observational network comprises automatic weather stations, manual gauges, river gauges, radiosonde launches, and radar installations located across coastal, Andean, and Amazonian basins including the Rímac River, Mantaro River, and Ucayali River. SENAMHI’s infrastructure modernization has included automated surface observing systems interoperable with regional networks like the Sistema de Información Hidrológica del Perú and satellite data from platforms such as GOES, Meteosat, and Sentinel-3. Research instrumentation and data-sharing agreements link SENAMHI to the National Aeronautics and Space Administration, European Space Agency, and regional observatories like the Instituto Geofísico del Perú. Maintenance and expansion of observational arrays are often conducted with support from development banks and technical partners including the German Agency for International Cooperation and Japan International Cooperation Agency.
Forecasting activities combine statistical and dynamical models, now incorporating numerical weather prediction systems informed by global models from the European Centre for Medium-Range Weather Forecasts, Global Forecast System, and regional downscaling tools developed with university partners. Research priorities include Andean meteorology, convective systems over the Amazon, and cryospheric hydrology tied to the Cordillera Blanca and tropical glaciers studied by teams from Rutgers University, University of Colorado Boulder, and University of Cambridge. SENAMHI scientists publish with collaborators at the International Centre for Integrated Mountain Development, Latin American Meteorological Society, and participate in programs like the Global Framework for Climate Services.
SENAMHI engages in bilateral and multilateral cooperation with organizations such as the World Meteorological Organization, United Nations Office for Disaster Risk Reduction, Intergovernmental Panel on Climate Change, and regional networks including the Andean Community and Pan-American Climate Studies. Technical exchanges and training have involved counterparts like Servicio Meteorológico Nacional (Mexico), Instituto Nacional de Meteorología (Chile), NOAA, and the UK Met Office. Disaster response coordination has been undertaken with the International Federation of Red Cross and Red Crescent Societies and humanitarian agencies operating in Peru such as UNICEF and the World Food Programme.
SENAMHI has faced critique over data gaps in remote Andean and Amazonian regions, delayed release of warnings during rapid-onset events affecting communities in Puno, Ancash, and Loreto, and debates about resource allocation involving the Ministry of Economy and Finance (Peru). Reports by NGOs and academic audits citing institutions like the Peru Climate Change Platform and the Comisión de Ética Pública highlighted challenges in transparency, data quality, and coordination with municipal emergency services such as the National Civil Defense System. Reforms and international funding have aimed to address these criticisms through capacity-building projects with partners including the Inter-American Institute for Cooperation on Agriculture and the Global Environmental Facility.
