Wildfires Disrupt Daily Life in Manaus, Brazil

Wildfires in Brazil's Amazonas state are causing a significant disruption to daily life in Manaus, the largest city in the region.

The city of Manaus has been affected by heavy smoke from fires in surrounding municipalities and neighboring states, with air quality reaching unhealthy levels. The concentration of pollutants in the air averaged 196 micrograms per cubic meter, far exceeding the normal range of 3 to 9 micrograms per cubic meter.

Public school classes were canceled due to the poor air quality, and residents are being advised to wear face masks when outdoors. Municipal administrative offices have also suspended in-person work, citing the deteriorating air quality as a health concern.

Satellite data from both state and federal authorities shows clusters of fire hotspots near Manaus and in southern Amazonas state, with some fires also detected near the city of Santarem in neighboring Para state.

The dry season has brought a significant increase in fire hotspots across the Brazilian Amazon, with nearly 50% more recorded this year compared to the same period in 2025. However, the current number of hotspots is still about 53% lower than the historical average.

Fire activity has shifted southwards since June, initially concentrated in Roraima and Amapa states but now increasing near Manaus and around Santarem in Para state. This shift in fire patterns could have significant implications for local communities and the environment.

Climate experts warn that El Niño's effects on the region may be more severe in 2027, potentially disrupting the rainforest's next rainy season. This phenomenon has been linked to increased temperatures and drought in the Amazon, setting the stage for devastating wildfires.

The threat of drought, heat, and fires is prompting officials to urge preparations for the developing El Niño climate pattern. In recent years, El Niño events have led to severe drought and record-breaking wildfires in the Amazon, with temperatures rising 2 to 4 Celsius above historical averages during the 2023 and 2024 events.

The Amazon rainforest is a critical component in regulating global climate patterns, storing massive amounts of carbon dioxide and producing atmospheric moisture that affects weather conditions worldwide.

Brazil's Environment Ministry has taken action to combat wildfires in Amazonas state, deploying fire crews and aircraft to help extinguish the blazes. The ministry has also notified landowners of rural properties to take measures to prevent and fight wildfires, with on-the-ground inspections being stepped up to curb new fires and investigate the use of fire for illicit purposes.

The efforts by Brazil's Environment Ministry are a crucial step in mitigating the impact of wildfires in Amazonas state, which is already experiencing severe drought and record-breaking temperatures due to recent El Niño events.
