Weather in September
Temperature
September marks a gentle change in average high-temperature, declining from August's tropical 89.6°F (32°C) to a moderately hot 84.2°F (29°C). The nighttime temperature dips to a comfortable 66.4°F (19.1°C) on average during September.Heat index
For most parts of September, the heat index is evaluated at 84.2°F (29°C). If one remains active during constant exposure, it might cause exhaustion and heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
