Weather in September
Temperature
September records an average high-temperature of a still tropical 86.7°F (30.4°C), indicating a minor variation from the preceding month. Throughout the nights in September, an average low-temperature of 68°F (20°C) is noted.Heat index
September's average heat index is estimated at a sweltering 100.4°F (38°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
