Overnight Minimum Temperature Forecast – January 2–3
A cooler early-morning period is expected across Puerto Rico tonight, with around a 75 percent chance of minimum temperatures falling below 60°F between 3 and 6 AM AST. The highest probabilities are forecast across interior and higher-elevation areas, particularly near northern Ponce, southern Jayuya, and southern Ciales.
Overnight low temperatures in these areas are expected to range from the mid to upper 50s, which is typical for January during the tropical winter season. Coastal areas and the U.S. Virgin Islands are expected to remain warmer, with minimum temperatures generally staying above 60°F.
