Weather in September
Temperature
The shift into September records an average high-temperature of a still tropical 86.9°F (30.5°C), subtly varied from August's 90.7°F (32.6°C). The nighttime temperature dips to a pleasant 68.9°F (20.5°C) on average during September.Heat index
September's heat index is calculated to be a fiery hot 98.6°F (37°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. 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 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. As body temperatures escalate without effective heat release, one might face dehydration threats.
