Weather in September
Temperature
September brings an average high-temperature of a still moderately hot 29.9°C (85.8°F), nearly identical to the preceding month. Throughout the nights in September, an average low-temperature of 18.7°C (65.7°F) is noted.Heat index
For most parts of September, the heat index is calculated to be a very hot 35°C (95°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance 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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
