Weather in September
Temperature
September's arrival coincides with a soft drop in the average high-temperature, subtly decreasing from August's hot 93.7°F (34.3°C) to a still tropical 87.1°F (30.6°C). Throughout September, Stamps registers a consistent average low-temperature of 65.8°F (18.8°C).Heat index
September's mean heat index is calculated to be a fiery hot 98.6°F (37°C). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
