What is El Niño?
El Niño is an iPhone app that provides a real-time picture of conditions in the tropical Pacific Ocean using public NOAA data. It shows whether the Pacific is warming, cooling, or uncertain, and presents the information through a clear summary, interactive maps, charts, and comparisons with past El Niño and La Niña events. The app is designed to answer the key question first, what’s happening now, while offering deeper details for those who want to explore further.
The app includes a Pacific sea-surface temperature anomaly map that highlights the Niño 3.4 region, weekly and monthly charts to track changes over time, and a comprehensive ENSO Signal Score from 0 to 100 that combines ocean and atmospheric data. Users can share a daily snapshot with source details, add a Home Screen widget, and receive alerts. No account is required, and all data is drawn from trusted NOAA sources.
