Puerto Rico Fires

Daily Wildfire Report for Puerto Rico - August 05, 2026

Overview

Puerto Rico is experiencing an elevated fire risk driven by a severe and rapidly intensifying dry period. Late May to late July was the driest such period in San Juan's 127-year history, with broad areas of the island experiencing 60-day rainfall deficits of 4 to 8 inches, and locally up to 14 inches in the El Yunque National Forest. Abundant herbaceous vegetation that grew during a wetter-than-normal winter and early spring is now dormant, contributing heavily to wind-driven fires as the impacts of a strengthening El Niño become abundantly clear. The National Interagency Fire Center (NIFC) has forecast above-normal significant fire potential for Puerto Rico and the neighboring U.S. Virgin Islands throughout August.

Current Situation

Fire Activity: There is currently an above-normal significant fire potential across Puerto Rico, particularly in the southern and eastern municipalities. The frequency of brush fires has surged over the last 72 hours, adding to the more than 300 reports recorded in recent weeks. These wildfires have been notably intense and expansive, causing rare damage to local infrastructure. The Puerto Rico Fire Department (PRFD) and interagency partners are heavily focused on rapid initial attack and structure protection.

Key Fires: While there are no nationally managed mega-fires currently active on the island, local firefighters are actively working to suppress numerous fast-moving brush fires across the southern plains, stretching from Cabo Rojo to Cidra. These fires are primarily fueled by dormant herbaceous vegetation, dry brush, and exotic grasses across the dry coastal plains. The rapid spread of these smaller fires is exacerbated by critically dry conditions, high winds, and severely depleted soil moisture, putting local agricultural assets and rural infrastructure at risk.

Prescribed Burns and Land Management: The PRFD, in collaboration with the USDA Forest Service's Institute of Tropical Forestry and the Department of Natural and Environmental Resources (DNER), is prioritizing fuel mitigation. This includes the implementation of fuel reduction through controlled burns and the creation of firebreaks to protect vulnerable communities.
Burn Bans: Due to the severe regional drought and elevated fire risks, the neighboring U.S. Virgin Islands implemented a territory-wide burn ban earlier this week. Residents in Puerto Rico are strongly urged to follow similar precautions, avoiding all outdoor burning and exercising extreme caution with any activity capable of producing sparks.

Air Quality: A drier air mass accompanied by Saharan dust is currently present over the region, with a moderate to high concentration plume expected to thicken by Thursday. This will result in widespread hazy skies and reduced air quality. Smoke from localized brush fires will further impact air quality in the immediate vicinity of the southern and eastern coastal plains. Sensitive groups should take necessary precautions.

Weather and Wind Warnings

Current Weather: The region is experiencing near-record warmth and dryness, which has triggered grass fires and critically low stream levels. While isolated scattered thunderstorms may occur locally, a generally drier air mass is dominating the region, bringing above-normal temperatures and lower overall rainfall coverage.
Forecasted Weather: The National Weather Service in San Juan has highlighted elevated fire weather conditions driven by the dry air mass. Critically dry fuels persist across the island, with ongoing severe rainfall deficits keeping drought indices extremely high. The U.S. Drought Monitor indicates Severe Drought (D2) across Puerto Rico's southern plains, with Moderate Drought (D1) spanning the eastern and southern half. Forecast models indicate a greater than 70% likelihood of below-normal precipitation and above-normal temperatures continuing through October 2026. Easterly winds of 10 to 15 mph, with frequent higher gusts, will continue to fan potential flames and support elevated fire weather conditions over the next 72 hours.

Recommendations

Public Awareness: Residents are advised to be mindful of fire traffic and potential smoke impacts. It is crucial to have an emergency plan in place and to clear dead brush from properties to reduce the risk of catastrophic fires. Diminishing surface and groundwater levels have also triggered water rationing for agricultural users in the south-central and southwest regions; residents should conserve water where possible and adhere to local guidelines.
Resource Allocation: PRFD operates from a central hub in Juncos and has deployed six all-hazard fire crews across the island. Agencies are training for increased fire risk and conducting fuel mitigation projects to clear high-risk areas. Equipment and tools funded by the State and Volunteer Fire Assistance Program are actively being utilized to ensure rapid response.
