Weather in September
Temperature
September signifies a minor drop in average high-temperature, transitioning from a tropical 88.3°F (31.3°C) in August to a moderately hot 80.6°F (27°C). In the month of September, the nighttime temperature dips to a steady average of 59.2°F (15.1°C).Heat index
The heat index value for September is computed to be 82.4°F (28°C). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. 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.
