Weather in September
Temperature
The beginning of September brings a minor change in the average high-temperature, shifting from a hot 86.7°F (30.4°C) in August to a moderately hot 81°F (27.2°C). An average minimum temperature of 64°F (17.8°C) is recorded during the month of September.Heat index
For most parts of September, the heat index is evaluated at a tropical 86°F (30°C). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a numerical representation of warmth when taking temperature and moisture levels into account. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and 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 largely significant for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
