Even under the influence of La Niña, which tends to reduce the average global temperature, the summer has been the hottest since 1961, according to Inmet
The tests of the aggravation of the climatic crisis are clear: 2024 was the hottest year ever recorded, with an average global increase of 1.55 ° C compared to the pre-industrial period. In Brazil, the high temperatures were also present and the summer 2024-2025 were classified as the hottest sixth in about 60 yearsAccording to the National Institute of Meteorology (Inmet). The highest maximum temperature reached 43.8 ° C in February in Rio Grande do sul.
Summer began on December 21, 2024 and ended this Thursday 20, with the arrival of autumn. TO EarthInmet made the list of 10 hottest days recorded this summer available, whose average temperature reached 25.81 ° C, 0.34 ° C above the historical average (25.47 ° C).

Nine of the ten highest temperatures recorded this summer took place this year: it was concentrated 8 in February and the same week. Another prominent aspect is that among the ten discs, five refer to the state of Rio de Janeiro. Already The hottest day was in Quaraí, Rio Grande do Sul, on February 4, where thermometers reached 43.8 ° C.
Take a look at the list, organized by Inmet:
- Quaraí (RS): 43.8ºC, 02/04/2025;
- Salinópolis (PA): 43.2 ° C, 22/12/2024;
- Niterói (RJ): 42.2ºC, 17/02/2024;
- Porto Murtinho (MS): 42.1ºC, 17/01/2025;
- Silva Jardim (RJ): 42ºC, 17/02/2025;

- Seropéica-Ecology Agricultural (RJ), 41.1ºC, 17/02/2025,
In the past summer, the highest temperatures ever recorded in Bom Jesus do Piauí (PI), on January 30, 2006 and in Orleans (RS), on January 6, 1963. In both cases the maximums reached 44.6 ° C. The story surrounding the problem began to be recorded in 1961.
Hottest summers
During the summer, Brazil was under the influence of La Niña, a phenomenon that tends to reduce the average global temperature, cooling the Pacific waters. Even so, the station was among the 10 hottest in the historical inmet series.
In other cases, of even warmer summers, the influence was from El Niño, which causes heating above the average of the Pacific waters and improves temperatures in various regions of the planet. As in the case of the summer between the end of 2023 and the beginning of 2024, that is, both the summer of the beginning of 2024 and the summer of the end of the year, have generated notices.
Take a look at the hottest summers ever recorded in Brazil, according to Inmet:
- 2023/2024: Average temperature observed of 26.20 ° C;
- 2015/2016: Average temperature observed of 26.14 ° C;
- 1997/1998: Average temperature observed of 26.07 ° C;
- 2012/2013: Average temperature observed of 25.90 ° C;
- 2009/2010: Average temperature observed of 25.83 ° C;
- 2024/2025: Average temperature observed of 25.81 ° C.
Autumn has begun and the heat continues
Autumn began this Thursday 20, but most of the country does not greet the heat with the end of summer. This is because it is expected that the above average temperatures should be characterized by months with milder climates.
For March, April and May, the climatic models indicate a greater probability of the occurrence of Temperatures above the normal range expected for the station most of the country, mainly in the center, north -est and south of the country.
Among the “out of season heat” in points in the central-southern country, as well as in some parts of the east of the north-east, rainfall should be below average.
The Midwest and the South -East have equally probably probably to the possibilities of rain, above or under the normal climatological range provided for the fall. But there is a warning: for these regions it is expected that, until mid -April, episodes of the phenomenon known as the convergence area of the southern Atlantic (ZCA), which promotes abundant rains, intensity and persistence – as rain showers at local level, accompanied by electrical discharges and gums.
North, there are no indicators that the temperature is above average. At the same time, this is the region with the provision of greater reliability for the probability of rainfall above the normal interval.
These are the salient points of the most recent joint bulletin developed by the Center for Time Precasting and Climate Studies (Cptec), the National Institute for Space Research (Inpe) and Cearense Foundation for Meteorology and Water Resources (Fundame), issued by the Ministry of Science, Technology and Innovation.
