Canícula, also known as the “dog days of summer,” is a period of intense heat and humidity that usually occurs between early July and early September. During this time, people often struggle with extreme heat and feel lethargic and exhausted, making it difficult to be physically active and go outdoors. This term originates from the ancient belief that the star Sirius, also known as the “Dog Star,” was responsible for the hot and humid weather.

As Canícula approaches, Mexico is bracing for the scorching temperatures and dry season that will sweep the country in the coming months. This annual weather phenomenon poses a threat to the health and well-being of the population, as temperatures can reach over 37°C. Various factors, such as climate change, urbanization and weather patterns, contribute to these heat waves, which can have a significant impact on human health, wildlife, agriculture and infrastructure.

Which states will be most affected by this intense heat wave?

According to the Government of Mexico, the 2024 heat wave is expected to hit the country in the last days of July and last approximately 40 days. These are the 17 states where the heat wave is expected to bear the brunt:

  • Campeche
  • Hidalgo
  • Michoacán
  • Guerrero
  • Tamaulipas
  • Chiapas
  • Colima
  • Morelos
  • Oaxaca
  • Quintana Roo
  • Puebla
  • San Luis Potosí
  • Nuevo León
  • Tabasco
  • Yucatán
  • Veracruz
  • Tlaxcala

To stay safe during this period, the government has advised citizens to take the necessary precautions, such as staying hydrated, avoiding direct sun exposure, and taking breaks in cool or shaded areas when working outdoors. However, it is not only humans who are affected by the intense heat. The lack of precipitation during Canícula can cause droughts and forest fires, upsetting the natural balance of the environment and threatening the survival of wildlife.

Canícula is a severe weather phenomenon that has significant effects on human health, the environment and wildlife. It is essential that people are aware of its potential dangers and take the necessary precautions to protect themselves and the environment during this period of intense heat.
