Scientists have identified 2026 as a record-breaking El Niño year characterized by significant ocean temperature anomalies. This weather pattern is expected to drive increased storm intensity and flooding across Southern California this winter.
Why it matters
The El Niño cycle shifts the jet stream to direct more moisture toward the coast, creating a heightened risk for infrastructure and public safety. Officials are bracing for severe weather impacts that could challenge regional flood management and coastal stability.
Equatorial ocean surface temperatures are 4 degrees Celsius above normal, while subsurface temperatures exceed the norm by 10 degrees Celsius. Additionally, thermal expansion has raised ocean surface height by approximately 6 inches.
The players
NOAA
The National Oceanic and Atmospheric Administration is a federal agency focused on conditions of the oceans, major waterways, and the atmosphere.
The details
Warmer water in the Pacific Ocean shifts the jet stream south, steering intense winter storms directly toward the California coast. Kelvin waves are currently transporting this warm water eastward across the Pacific, facilitating the El Niño development.
Timeline
1950 serves as the baseline year for measuring El Niño intensity.
The El Niño cycle has shown increased intensity over the last 40 years.
A breach of the Los Angeles Aqueduct occurred in 2023.
Southern California faces increased storm and flooding risks during the winter of 2026-2027.
Wetter conditions are expected to peak between February and April 2027.
Seasonal Patterns
The 2026 event follows the established pattern of the El Niño Southern Oscillation cycle but represents an extreme shift in projected intensity. This year aligns with historical trends that show an increase in the intensity of El Niño cycles over the last four decades.
Residents should prepare for an increased risk of severe storms and coastal flooding throughout the coming winter months. Local authorities recommend monitoring official weather advisories for potential impacts on regional infrastructure and emergency services.
The takeaway
Understanding the intensity of this El Niño cycle is essential for residents in flood-prone areas to mitigate potential property damage. Proactive maintenance of drainage systems and emergency readiness can help minimize the effects of the predicted severe winter weather.
