Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from a tropical 92.3°F (33.5°C) in August to a moderately hot 83.8°F (28.8°C). The month of September records an average low-temperature of 64.4°F (18°C).Heat index
During September, the heat index is evaluated at a hot 86°F (30°C). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
