Weather in September
Temperature
September's presence marks an average high-temperature of a still hot 88°F (31.1°C), subtly varied from August's 91.2°F (32.9°C). An average nighttime temperature of 72.5°F (22.5°C) is recorded during September.Heat index
The heat index in September is evaluated at an extremely hot 104°F (40°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. 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 'real feel' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
