November 2023: Brazil faces severe drought. The crucial diagnosis reveals the complexity, strongly influenced by the persistent El Niño until April.
In November 2023, Brazil faced a difficult drought scenario, with different regions of the country affected in different ways. Detailed monitoring reveals not only intensifying drought in some areas, but also encouraging signs of improvement in others.
Drought monitoring
The Drought Monitor, through the Drought Monitor Map, plays an essential role in understanding and monitoring drought in Brazil. By consolidating updated monthly data, this collaborative process between experts and federal and state institutions integrates technical and scientific knowledge. With short- and long-term indicators, the Monitor not only offers a comprehensive view of drought developments, but also stands out as a proactive tool, facilitating decision-making and policy making at multiple scales, while promoting integrated and collaborative drought management.

North-East Region
In the North-East Region, negative precipitation anomalies and above-average temperatures have caused an intensification of the drought. The south of Bahia and the west of Sergipe and Alagoas went from a moderate (S1) to severe (S2) condition. States such as Maranhão, Ceará, Pernambuco and Bahia have also seen the progress of a moderate drought. However, there was relief in Piauí, with the regression of the moderate drought, and a weakening in the north of Rio Grande do Norte, going from moderate (S1) to weak (S0).
South-eastern region
The southeast faced challenges with below-normal rainfall and high temperatures, resulting in worsening drought conditions in Minas Gerais and Espírito Santo. The north of Rio de Janeiro saw a weak drought (S0), indicating a worrying situation in the region.
Southern region
Unlike other regions, Southern states remained free of relative drought, thanks to the persistence of above-average precipitation in November.
Northern Region
Negative rainfall anomalies in the northern region have caused an advancement of the drought. Salient factors include a weak drought (S0) in southeastern Amazonia and Pará, a moderate drought (S1) in central Rondônia and eastern Amazonia, a severe drought (S2) in southeastern Acre and southern Amazonia, and a extreme drought (S3) in northern Acre and south-central Acre. and the southwestern Amazon. In Tocantins, the area of moderate drought (S1) increased, while in Pará there were signs of improvement, with moderate drought (S1) decreasing in the north and easing in the northwest.
Midwest Region
The Central-West Region faced worsening conditions, with the progression of weak (S0) and/or moderate (S1) droughts in all States and the Federal District. However, relief was recorded in the southeast of Mato Grosso, with a retreat from moderate drought (S1), and in the west of Goiás, where the drought changed from moderate (S1) to weak (S0).
November 2023 highlighted the complexity of the drought phenomenon in Brazil, with different regions facing different challenges, of which the El Niño phenomenon is one of the main causes. While conditions have worsened in some areas, others have seen encouraging signs of improvement. Continuous monitoring of these changes is critical to understanding and appropriately responding to the impacts of drought in the country. It is worth noting that the El Niño phenomenon is expected to last until April and will continue to influence the country’s precipitation and temperature.
