Hazy Skies, Extreme Heat, and Fire: Conditions to Expect in Puerto Rico This Weekend

Updated Jul 4, 2026 · via Primera Hora

Puerto Rico is expected to experience dry, windy, and hot conditions this weekend, with a high concentration of Saharan desert dust particles in the air. The weather conditions will bring a high risk of forest fires, particularly in the southern coastal plain, and will also lead to hazy skies, reduced visibility, and poor air quality.

The National Meteorological Service predicts that a typical summer wind pattern will persist until Monday, with moderate winds from the east-southeast, leading to scattered showers in the east and isolated showers in the interior and west. A slight increase in humidity is expected between Sunday and Monday, but the risk of flooding will remain low.

The heat index is expected to exceed 100 degrees Fahrenheit, especially in coastal and urban areas, posing a risk to sensitive individuals. The public is advised to take precautions against the heat and poor air quality.
