Fire Forecast Amazon Region


The fire season in the southern Amazon runs from June to November, with peak burning activity in September along the eastern and southern Amazon forest frontiers, a swath sometimes referred to as the "arc of deforestation". Year-to-year variability in fires is strongly linked to climate anomalies, and both the El Niño Southern Oscillation in the Pacific Ocean and Atlantic Multi-decadal Oscillation influence drought conditions and the risk of fires across the southern Amazon.


2019 Fire Season Updates:

August 24th, 2019
Figure: Cumulative active fire detections through 8/22/2019 from MODIS and VIIRS confirm that 2019 is the highest fire year since 2012 (the start of the VIIRS record) across the seven states that comprise the Brazilian Amazon. In addition, fires in 2019 are more intense than previous years, measured in terms of fire radiative power, consistent with the observed increase in deforestation

July equalled, and maybe surpassed, the hottest month in recorded history


According to new data from the World Meteorological Organization and Copernicus Climate Change Programme, July at least equalled, if not surpassed, the hottest month in recorded history. This follows the warmest ever June on record.

The data from the Copernicus Climate Change Programme, run by the European Centre for Medium-Range Weather Forecasts, is fed into the UN system by WMO. The figures show that, based on the first 29 days of the month, July 2019 will be on par with, and possibly marginally warmer than the previous warmest July, in 2016, which was also the warmest month ever.

The latest figures are particularly significant because July 2016 was during one of the strongest occurrence of the El Niño phenomenon, which contributes to heightened global temperatures. Unlike 2016, 2019 has not been marked by a strong El Niño.

"We have always lived through hot summers. But this is not the summer of our youth. This is not your grandfather's summer," said UN Secretary-General António Guterres, announcing the data in New York.

July 2019 will be around 1.2°C warmer than the pre-industrial era, according to the data.

"All of this means that we are on track for  the period from 2015 to 2019 to be the five hottest years on record. This year alone, we have seen temperature records shattered from New Delhi to Anchorage, from Paris to Santiago, from Adelaide and to the Arctic Circle. If we do not take action on climate change now, these extreme weather events are just the tip of the iceberg. And, indeed, the iceberg is also rapidly melting," Mr Guterres said.

"Preventing irreversible climate disruption is the race of our lives, and for our lives. It is a race that we can and must win," he underlined.
