Weather in September
Temperature
The arrival of September corresponds with a minor reduction in the average high-temperature, down from August's torrid 95.9°F (35.5°C) to a tropical 88.7°F (31.5°C). Marquez registers a consistent average low-temperature of 68.9°F (20.5°C) during September.Heat index
The heat index value for September is calculated to be a very hot 102.2°F (39°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
