As spring unfolds and temperatures rise in Mexico, the onset of a commonly experienced climatic phenomenon known as 'canícula' is approaching. This period is marked by intense heat, clear skies, and a significant decrease in rainfall. According to the Federal Government's National Disaster Prevention Center (Cenapred), the canícula is a summer climate event that varies greatly depending on the region of the country.

Determining the exact start date of the canícula is challenging, as it does not have a fixed beginning. However, Cenapred indicates that it usually occurs during the last fortnight of July, lasting approximately 40 days and extending into August. Meteorologists emphasize that this climatic phenomenon can show considerable regional variation, affecting different parts of Mexico in different ways.

As the country prepares for this extreme heat wave, officials advise citizens to be mindful of hydration and heat exposure. Understanding when and how the canícula will manifest can aid in better preparation, especially in states that are typically hardest hit by extreme temperatures, thus emphasizing the importance of public awareness and safety measures ahead of the summer months.
