Weather in September
Temperature
Transitioning from August to September involves a subtle drop in average high-temperatures, descending from a tropical 93.4°F (34.1°C) to a still hot 87.6°F (30.9°C). Nighttime temperature lowers to an average of 72.7°F (22.6°C) in September.Heat index
For September, the heat index is calculated to be a torrid 102.2°F (39°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial 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.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
