Extreme heat and low humidity in Piauí

Overview

The Brazilian state of Piauí has experienced a period of extreme heat and critically low humidity. Initially, the Secretariat of Environment and Water Resources (Semarh) issued alerts due to a high-pressure atmospheric system that inhibited cloud formation, raising temperatures toward 40°C and creating a significant risk of forest fires.

By mid-September, the heatwave persisted with cities such as Castelo do Piauí, Oeiras, and Piripiri recording temperatures exceeding 40°C. The region has also seen intense temperature fluctuations; for example, Oeiras recorded a high of 40.7°C followed by a low of 15.6°C. Humidity levels remained dangerously low, with some areas dropping to 12%.
