Weather in September
Temperature
On the advent of September, Santa Fe's average high-temperature exhibits a minor adjustment to a still tropical 86.2°F (30.1°C) from August's 90.9°F (32.7°C). An average low-temperature of 75°F (23.9°C) is expected during September.Heat index
For September, the heat index is calculated to be a torrid 98.6°F (37°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. 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. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
