The canícula in the Rio Grande Valley, known as the “dog days of summer,” typically begins mid-July and extends until August. Generally, the canícula starts on July 14th and ends on August 24th.
Based on the current date of July 25, 2024, the canícula has already begun, and we are right in the middle of the hottest summer period in the Rio Grande Valley. But why do we have to deal with this hot phenomenon every year?
The canícula is a period known for its intense heat and scarce precipitation, affecting regions like the Rio Grande Valley. This phenomenon is due to several climatological factors:
- Solar Position: During this period, the sun’s position causes its rays to hit the region more directly, significantly increasing daytime and nighttime temperatures.
- High Atmospheric Pressure: The presence of high-pressure systems in the atmosphere during the canícula helps to keep hot air trapped near the earth’s surface. These systems also inhibit cloud formation and, therefore, rain, exacerbating the sensation of heat.
- Solar Radiation and Humidity: The Rio Grande Valley, near the Gulf of Mexico, experiences high humidity levels. High temperatures and elevated humidity create muggy conditions, making the heat feel even more intense.
- Changes in Wind Patterns: During the canícula, wind patterns change and can bring hot air from the Chihuahua Desert or the southwestern United States, further increasing temperatures.
Dealing with the canícula requires certain precautions to minimize its negative effects on health and well-being. It is important to stay hydrated, avoid prolonged sun exposure, wear light-colored and lightweight clothing, and take advantage of the cooler hours of the day for outdoor activities.
This annual phenomenon, though challenging, is an inherent climatic characteristic of the Rio Grande Valley region. Understanding its causes and effects allows its inhabitants to prepare adequately and mitigate its impacts. Thus, in the midst of these “dog days of summer,” being well-informed and taking preventive measures is key to enduring this hot season.
The word “Canícula” is translated to English as “Dog Days.” This term refers to the hottest period of the year, typically in the Northern Hemisphere in late July and August. The name originates from the ancient belief that this period coincided with the heliacal rising of Sirius, the Dog Star, which was thought to contribute to the extreme heat.
The Canícula is often associated with sweltering heat and stagnant air, leading to a common saying in English that describes this period as the “dog days of summer”
