Weather in September
Temperature
The transition into September shows a subtle variation to a moderately hot 81.1°F (27.3°C) from August's 86.2°F (30.1°C) in the average high-temperature. During the month of September, the temperature generally drops to a low average of 61.3°F (16.3°C).Heat index
The average heat index in September is computed to be a tropical 86°F (30°C). Continuous activity in exposure could lead to a feeling of fatigue and heat cramps.Know that the heat index computations account for shaded terrains and slight winds. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
