In Manaus, Brazil, smoke from wildfires disrupted daily life on Friday as the country's dry season neared its peak. The city suspended in-person work at municipal administrative offices and canceled public school classes due to deteriorating air quality. Residents were advised to wear face masks.

The city reported that pollutant concentrations averaged 196 micrograms per cubic meter, a level considered unhealthy and far above the normal range of 3 to 9. The city government stated that heavy smoke from fires in other municipalities within Amazonas state and in neighboring states had been affecting Manaus for several days. This situation, they noted, extended beyond the capital and posed a threat to the health and quality of life for thousands of families.

State and federal satellite data indicated clusters of fire hotspots near Manaus, in southern Amazonas state, and close to Santarem in Pará state. According to Brazil’s National Institute for Space Research, approximately 33,556 fire hotspots were recorded in the Brazilian Amazon this year up to Thursday. This figure represents a nearly 50% increase compared to the same period in 2025, though it remains about 53% below the historical average.

The location of fire hotspots has shifted across the Amazon since the dry season began in June. Initially concentrated further north in Roraima and Amapa states, they have more recently increased in southern areas, including near Manaus, southern Amazonas state, and around Santarem in Pará state. Studies suggest that El Niño's effects could intensify in 2027, potentially disrupting the rainforest's next rainy season. Officials have urged preparations for drought and heat, as El Niño, a climate phenomenon that typically raises temperatures and increases drought in the Amazon, develops.

The Amazon is a critical ecosystem for global climate regulation, storing vast amounts of carbon dioxide and generating atmospheric moisture. Most wildfires in the region are human-caused rather than natural. Brazil's Environment Ministry reported deploying fire crews and aircraft to combat fires in Amazonas state and notified rural property owners to take preventative measures. The ministry also stated that on-the-ground inspections were being increased to curb new fires and investigate illegal fire use.

Disagreement on fire hotspot numbers

The National Institute for Space Research reported about 33,556 fire hotspots in the Amazon this year, nearly 50% more than the same period in 2025. However, France24 reported that the mayor’s office of Manaus attributed the air quality deterioration to 749 fire bulbs counted on Wednesday in Amazonas.

What the coverage left out

None of the left-rated or centre-rated reports mentioned the specific details of Brazil's Environment Ministry's actions, such as deploying fire crews and aircraft, notifying rural property owners, or stepping up on-the-ground inspections to curb new fires and investigate illegal use of fire.

Questions about this coverage

How did the left and right cover Manaus suspends work due to wildfire smoke and poor air quality?
Of the 19 outlets on this story carrying a published leaning rating, 53% are rated left, 42% are rated centre, 5% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it. The sections above set out what each side emphasised, in its own terms.
Is Manaus suspends work due to wildfire smoke and poor air quality left or right?
Neither side dominates it. Of the 19 rated outlets on this story, 53% are rated left, 42% are rated centre, 5% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
Is the coverage of Manaus suspends work due to wildfire smoke and poor air quality biased?
Manaus suspends work due to wildfire smoke and poor air quality is one event reported by 19 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which side is not reporting Manaus suspends work due to wildfire smoke and poor air quality?
When we first saw this story, outlets rated right had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
Which outlets covered Manaus suspends work due to wildfire smoke and poor air quality?
19 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
Why were work and school suspended in Manaus?
In-person work at municipal administrative offices in Manaus was suspended on Friday, and public school classes were canceled due to worsening air quality caused by smoke from wildfires. The city reported pollutant concentrations averaging 196 micrograms per cubic meter, a level considered unhealthy and significantly above the normal range.
How many fire hotspots were recorded in the Amazon?
Brazil’s National Institute for Space Research recorded approximately 33,556 fire hotspots in the Brazilian Amazon this year up to Thursday. This represents a nearly 50% increase compared to the same period in 2025, although it is still about 53% below the historical average.
What is El Niño's role in the Amazon fires?
El Niño is a climate phenomenon that typically raises temperatures and increases drought in the Amazon region. Studies suggest its effects could be more severe in 2027, potentially disrupting the rainy season and contributing to conditions that fuel wildfires. Officials have urged preparations for drought and heat associated with its development.
