Following a string of heat waves in the Latin American country, the authorities said that more than 100 people perished in Mexico in June as a result of the excessive heat.
According to scientists, global warming is causing more severe weather, with many nations currently hitting temperature records.
Also data from the health ministry provided on Wednesday, almost 1,000 heat-related crises were reported in Mexico between June 12 and June 25, and 104 of those emergencies led to fatalities.
There were previously eight documented deaths between April 14 and May 31 according to the authorities, for a total of 112.
According to the health ministry, dehydration was the second-leading contributing factor after heat stroke.
The most fatalities were reported in northern Mexico, where 64 deaths were reported in the state of Nuevo Leon in the northeast and 19 in the neighbouring state of Tamaulipas, which borders the similarly scorched US state of Texas.
The health ministry of Mexico reported that the state of Sonora in the country’s northwest recorded a high temperature of 49 degrees Celsius (120 degrees Fahrenheit) this week.
Between 30 and 45 degrees Celsius are the typical summertime maximum temperatures in Mexico, the report noted.
Authorities issue a warning that starting on July 1, a new heatwave might hit the 127 million-person nation.
The United Nations issued a warning in May stating that the combination of greenhouse gases and El Nino will almost certainly result in 2023–2027 being the warmest five-year period ever observed.
