Puente Quebrado, Mexico

Temperature

In the transition from August to September, Puente Quebrado reports an average high-temperature of a moderately hot 29.6°C (85.3°F), indicating a close resemblance to the prior month. Throughout September, the temperature falls to an average low of 20.4°C (68.7°F).

Heat index

During September, the heat index is calculated to be a torrid 38°C (100.4°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Humidity

The months with the highest humidity are August and September, with an average relative humidity of 86%.

Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Enhance your sun protection with tightly woven, yet airy clothing.
