Mato Grosso Faces Extreme Heat and Low Humidity This Week

Authorities in the Brazilian state of Mato Grosso have warned that a period of extreme heat and very low humidity is expected this week, with temperatures forecast to reach around 40°C.

The regional Civil Defence agency issued the alert after weather forecasts indicated that relative humidity could drop below 20% in several areas, including the state capital, Cuiabá.

Such low humidity levels are considered a risk to public health, as dry air combined with intense heat can lead to a range of physical problems.

Officials explained that the combination of high temperatures and dry conditions increases the likelihood of dehydration, heat exhaustion and respiratory difficulties.

Vulnerable groups, such as children, elderly people and those with pre-existing health conditions, are considered particularly at risk during this period.

In response, Civil Defence has issued a set of recommended precautions for residents to follow throughout the week.

These include drinking water regularly, even when not feeling thirsty, and avoiding strenuous outdoor activity during the hottest part of the day, generally in the early afternoon.

Authorities also suggested wearing light, loose clothing and seeking shade whenever possible to reduce direct exposure to the sun.

Additionally, the use of moisturising products for skin and eyes was recommended, since dry air can cause irritation and discomfort.

The weather forecast for Cuiabá reportedly mirrors the broader pattern expected across the rest of the state, with little relief anticipated in the coming days.

Officials have not specified an exact date for when conditions might improve, but they stressed that the alert remains valid for the entire week.

This type of weather event is not unusual for Mato Grosso during certain periods of the year, when the region typically experiences a dry season marked by low rainfall and rising temperatures.

Civil Defence has urged residents to stay informed through official weather updates and to take the recommended precautions seriously, given the potential health risks associated with prolonged exposure to hot, dry air.

The agency reiterated that early action and basic preventive measures can significantly reduce the chances of heat-related illness during this period of extreme weather.
