Weather in September
Temperature
The arrival of September denotes a barely perceptible change in the average high-temperatures to a still hot 31.3°C (88.3°F) from August's 32.3°C (90.1°F). The temperature lowers to an average of 19.8°C (67.6°F) during September nights.Heat index
The heat index value during September is appraised at a blisteringly hot 42°C (107.6°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Factoring in the heat index, values are geared towards shaded areas with light breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
