By Maria Rodriguez

1/31/2026

Climate Vulnerability Index (CVI): 78 (High Vulnerability)

Executive Summary:

Miami faces escalating heat vulnerability with temperatures exceeding 38°C for 45+ days annually. Urban heat islands in low-income neighborhoods show 5°C higher temperatures than coastal areas. Immediate cooling infrastructure needed.

Key Findings:

Downtown Miami records 45 extreme heat days per year, up from 28 in 2015

Little Haiti and Overtown neighborhoods lack tree cover and cooling centers

Elderly population (18% of residents) face 3x higher hospitalization rates during heat waves

Current cooling center capacity can only serve 12% of vulnerable population

Recommendations:

Deploy 15 new cooling centers in underserved neighborhoods by summer 2026

Plant 10,000 shade trees in urban heat island zones

Mandate cool roofs and reflective pavement in new construction

Establish heat emergency alert system with multilingual outreach
