Weather in September
Temperature
The commencement of September introduces an average high-temperature of a still tropical 86.4°F (30.2°C), closely mirroring the preceding month. An average low-temperature of 66.7°F (19.3°C) is noted during the nights in September.Heat index
The average heat index in September is calculated to be a fiery hot 96.8°F (36°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
