Weather in September
Temperature
White Hills experiences a minor change to a still hot 87.8°F (31°C) in average high-temperature during September, closely reflecting August. An average low-temperature of 69.3°F (20.7°C) is noted during the month of September.Heat index
The heat index value for September is calculated to be a blisteringly hot 104°F (40°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold particular significance for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
