Weather in September
Temperature
In Jerome, September's average high-temperature stands at a still tropical 87.1°F (30.6°C), closely related to the preceding month. During the nights of September, Jerome maintains an almost steady temperature with an average low of 78.4°F (25.8°C).Heat index
The heat index for September is calculated to be a very hot 100.4°F (38°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.When referencing the heat index, its values are suitable for shady environments and 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 'real feel' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. 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.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
