Weather in September
Temperature
The arrival of September brings an average high-temperature of a still tropical 86.7°F (30.4°C), nearly identical to August's 88.3°F (31.3°C). Throughout the month of September, White Beach observes an average nighttime temperature of 77.5°F (25.3°C).Heat index
September's average heat index is evaluated at a torrid 98.6°F (37°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
