Weather in September
Temperature
Welcoming September, Stephens notes an average high-temperature of a warm 85.1°F (29.5°C), nearly consistent with August's 90.1°F (32.3°C). Stephens experiences a nighttime temperature average of 65.1°F (18.4°C) during September.Heat index
The heat index value during September is estimated at a very hot 95°F (35°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
