With the start of summer comes the canícula, one of the hottest periods of the year in Mexico. In Guanajuato, beginning in July, this period will bring temperatures exceeding 35 degrees Celsius, decreased rainfall, and intense solar radiation.
According to the National Meteorological Service, this characteristic period of summer in Mexico, with its high temperatures and low rainfall, could have some negative effects on the population.
How does the canícula originate?
The canícula is an annual climatological phenomenon characterized by increased temperatures and a considerable decrease in rainfall. This temperature increase is due to excessive air heating, clear skies, and low precipitation.
During this time of year, the trade winds prevent cloud formation over the ocean. This leads to decreased rainfall, causing high temperatures to prevail.
When does the canícula begin in Guanajuato in 2026?
Although there is no exact date yet for this phenomenon, the dog days of summer (canícula) typically occur a few weeks after the summer solstice, which happens on June 21st. Based on this, it is expected that in 2026, the climatic event will begin around the first half of July in Guanajuato.
This period lasts approximately 40 days, which would mean it would end in August. However, the dates may vary depending on weather conditions.
Consequences of the dog days of summer on Guanajuato’s climate: Due to the significant impact on temperatures and rainfall, this period can have various consequences for the population, affecting health, agriculture, and the environment. Some of the risks present during the dog days of summer, according to INECOL (National Institute of Ecology), include:
Heatstroke and dehydration
Reduced water availability in rivers, lakes, and wells
Droughts
Decreased agricultural production
Increased forest fires
