Cuiabá Hits Hottest Day of the Year at 38.6°C
Cuiabá, Brazil, experienced its hottest day of the year on Sunday, February 26th, with temperatures reaching 38.6°C, according to the National Institute of Meteorology (Inmet). This surpassed the previous record of 37.1°C set just one day earlier, on Saturday, February 25th. Several other cities in the state of Mato Grosso also recorded high temperatures, including Cocalinho (38.0°C), Nova Xavantina (37.8°C), and Santo Antônio de Leverger (37.8°C). Cuiabá is no stranger to extreme heat; in October 2023, it recorded its all-time highest temperature of 44.2°C, placing it among Brazil's top ten hottest temperatures ever recorded. Since the 1940s, Cuiabá's maximum temperature has risen by 3°C, as noted by climatologist Rodrigo Marques from the Federal University of Mato Grosso (UFMT). Marques explained that while Cuiabá historically has high temperatures, averaging around 26°C, the current extreme heat is a result of a combination of factors. These include global warming, the city's geographical location, and a lack of vegetation within the capital.
The record-breaking temperatures in Cuiabá highlight the intensifying impacts of climate change, exacerbated by urban heat island effects due to limited vegetation and specific geographic factors. While global warming is a primary driver, local urban planning and land use policies play a significant role in mitigating or amplifying heat stress. The observed 3°C rise in maximum temperatures since the 1940s underscores a long-term trend that demands proactive adaptation strategies. Future urban development in such regions must prioritize green infrastructure and sustainable land management to build resilience against inevitable temperature increases, balancing economic growth with environmental and public health imperatives.
