The heat wave that has hit Mexico since mid-April, the third of the year, has killed eight people, the government announced.

Of the eight victims, seven succumbed to heatstroke and one to dehydration between April 14 and June 12, it said. Three people died in the state of Veracruz (east), two in Quintana Roo (southeast), two in Sonora (north) and one in Oaxaca (south).

In Mexico City, the temperature reached 35 degrees Celsius this week, which is a record temperature. In the center of the capital, the heat is stifling due to the crowds and gas emissions from road transport and businesses.

In Monterey (northeast), the temperature exceeds 40 degrees Celsius. In this affluent city, which suffered from a historic drought last year, water pressure dropped in households and increased use of air conditioners caused power outages.

The government of the state of Nuevo León, where Monterrey is located, has taken measures so that children take their lessons partly online and go to school for only two hours a day to avoid exposure to the sun.
