A study from the University at Albany reveals that extreme heatwaves in the Caribbean have become more frequent, longer, and severe over the past five decades. Analyzing climate data from 1971 to 2025, researchers found significant increases in heatwaves, particularly affecting urban areas like Havana and San Juan, with maximum “feel-like” temperatures exceeding 115°F. The worsening trend is attributed to rising global temperatures and El Niño events.
The study emphasizes the urgent need for improved heat preparedness policies and community education to protect public health and infrastructure. Jorge González-Cruz, leading the research, highlights the Caribbean’s vulnerability due to its tropical location and reduced cloud cover. Collaborative efforts, including the Caribbean Collaborative Action Network, aim to enhance resilience against climate extremes. The findings were published in Geophysical Research Letters.
