North America Regional Profile
Mexico
Sensitive Rain Seasons
- Winter season (November–March): Subtropical jet brings storms and cooler, wetter weather across northern Mexico.
- Summer season (June–October): Central and southern agricultural belts frequently experience rainfall deficits during El Niño.
Primary Environmental Hazards
- • Increased winter storminess, freeze risks, and heavy rainfall across northern border states
- • Suppression of the North American Monsoon in northwestern Mexico during onset phases
- • Increased Pacific tropical cyclone activity off Mexico's western coast
- • Suppression of Atlantic/Caribbean hurricane frequency affecting the eastern coast
Current 2026–27 El Niño Context for Mexico
