Pacific Region

NOAA/NCEI's Pacific Region Climate Services deliver tools and information to communities and businesses to reduce climate risk and improve resiliency. Located across a vast expanse of ocean, the Pacific Islands are exposed to changes in climate and weather that affect every aspect of life. Ocean and island ecosystems are changing with warming air and ocean temperatures, shifting rainfall patterns, changing frequencies and intensities of storms, decreasing base flow in streams, rising sea levels, and changing ocean chemistry. Together, these changes will make it increasingly difficult for many Pacific Islanders to sustain their unique communities and cultures.

Recent Activities

The U.S. - Affiliated Pacific Islands

The U.S. Affiliated Pacific Islands
  • Quarterly Climate Impacts and Outlooks
    NOAA’s Quarterly Climate Impacts and Outlooks draw on sources across NOAA to provide concise and accessible climate information for various regions of the United States, including the Pacific Region. These syntheses discuss the major climate events during the past three months and contain historical seasonal assessments as well as climate predictions and projections.
  • The Pacific Islands Climate Storybook
    The Pacific Islands Climate Storybook is a compilation of technical material, process guides, and activities. Use of the Storybook proved to be imperative to conduct the Climate Services Dialogues and build Climate Stories. The materials include a model agenda reflecting process flow, breakout guidance that contains sample questions, and examples of outcomes such as historical timelines, and a climate story template. Background and technical presentations provided associated with the various modules.
  • Probabilistic Estimates of Extreme Still Water Levels Under a Changing Climate
    The probabilistic estimates of extreme still water levels under a changing climate for specific locations in the Pacific Islands are part of a collaborative multiphase approach to develop innovative methodologies, best practices, and products in the region. Using preliminary results, they support vulnerability assessment, climate adaptation planning, and disaster risk reduction.
  • Pacific Islands Climate Forum
    The Pacific Centre for Environment and Sustainable Development and the Pacific Climate Information System hosted the Pacific Islands Climate Services Forum on January 21–25, 2013, in Suva, Fiji.

Decision Support Tools

    The Pacific Storms Climatology Products provide access to an integrated suite of products that delineate patterns and trends of storm frequency and intensity within the Pacific.
  • NOAA Coral Reef Ecosystem Integrated Observing System
    The NOAA Coral Reef Ecosystem Integrated Observing System provides a diverse suite of long-term ecological and environmental observations and information products to understand coral reef ecosystem conditions and processes.
  • NOAA Sea Level Rise and Coastal Flooding Impacts Viewer
    The NOAA Sea Level Rise and Coastal Flooding Impacts Viewer is a web-mapping tool aimed at visualizing potential impacts from sea level rise in Hawaii, Guam, and the Commonwealth of the Northern Mariana Islands.
  • Pacific Disaster Center
    The Pacific Disaster Center delivers products and services to support disaster risk reduction and hazard monitoring. Numerous resources can be found on the website.
  • Seasonal Climate Outlooks in Pacific Island Countries
    The Australian Bureau of Meteorology’s Seasonal Climate Outlooks in Pacific Island Countries is a decision support system for generating probabilistic predictions (seasonal climate outlooks) for rainfall, temperature, or other climate-related parameters.


  • Asia–Pacific Data–Research Center
    The Asia–Pacific Data–Research Center increases understanding of climate variability in the Asia–Pacific region by developing the computational, data management, and networking infrastructure necessary to make data resources readily accessible and usable.
  • NOAA OceanWatch - Central Pacific
    NOAA OceanWatch - Central Pacific acquires and processes satellite information and creates a variety of satellite data products for the Pacific Ocean region to serve as an updated source of daily regional satellite oceanographic observations.
  • Pacific Islands Ocean Observing System Voyager
    The Pacific Islands Ocean Observing System Voyager is an interactive map interface for visualizing and downloading oceanographic observations, forecasts, and other geospatial data and information related to the marine environment and beyond.
  • University of Hawaii Sea Level Center
    The University of Hawaii Sea Level Center collects, processes, distributes, and analyzes tide gauge data from around the world in support of climate research.

  • Climate Change in the Pacific: Scientific Assessment and New Research
    The Climate Change in the Pacific is a rigorously researched and peer-reviewed scientific assessment of the climate of the Western Pacific region. Building on the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, this two-volume publication represents a comprehensive resource on the climate.
  • Pacific ENSO Update
    This bulletin of the Pacific El Niño–Southern Oscillation (ENSO) Applications Climate Center provides information on climate variability related to the ENSO climate cycle for the U.S. Affiliated Pacific Islands.
  • Island Climate Update
    This monthly summary of the climate in the tropical South Pacific islands, with an outlook for the coming months, assists in dissemination of climate information in the Pacific region. This bulletin is a multinational project with collaboration from a number of Pacific nations and organizations.
  • Pacific Islands Climate Change Virtual Library
    This library is used by Pacific Island communities looking to implement climate change adaptation plans. The Virtual Library provides access to web-based climate change tools, including case studies, guidebooks, and methodologies for assessing vulnerabilities.
  • Pacific Islands Climate Education Partnership
    The Pacific Islands Climate Education Partnership developed a detailed strategic plan to collaboratively improve climate knowledge among the region’s students and citizens in ways that exemplify modern science and indigenous environmental knowledge, address the urgency of climate change impacts, and honor indigenous cultures.

Training and Professional Development

  • National Domestic Preparedness Training Center
    The National Domestic Preparedness Training Center engages with the Federal Emergency Management Agency and the University of Hawaii as well as with partners across the Pacific region to integrate the delivery of its trainings, products, and services.

Pacific Region RCSD – John Marra

John Marra

Dr. John J. Marra is the Regional Climate Services Director for the Pacific Region, based in Honolulu, Hawaii. He is also the Chair of the Pacific Climate Information System and an Adjunct Fellow at the East–West Center. For over 20 years, Dr. Marra has been working to bridge science, policy, and information technology to address issues related to natural hazards risk reduction and climate adaptation planning. His particular area of expertise is the development and dissemination of data and products associated with coastal inundation and erosion. Dr. Marra previously worked for the NOAA Integrated Data and Environmental Applications Center in Honolulu, Hawaii. While there he spearheaded a project on extreme storms—strong winds, heavy rains, and high seas—in the Pacific. Dr. Marra also worked at the NOAA Pacific Services Center, providing technical assistance to Pacific Island jurisdictions and supporting the integration of multidisciplinary research and observations to address issues associated with coastal natural hazards and community resilience. Before arriving in Hawaii in April 2002, he worked independently for almost 10 years in Newport, Oregon, as a consulting geologist for a broad range of private and public sector clients. Prior to that, he was the North Coast Field Representative for the State of Oregon’s Department of Land Conservation and Development. Dr. Marra received his PhD in geology from the University of Canterbury, in Christchurch, New Zealand.
