Weather in September
Temperature
The move into September indicates a slight reduction in the average high-temperature, down from August's hot 88°F (31.1°C) to a warm 81.9°F (27.7°C). September nights are marked by an average temperature drop to a comfortable 62.4°F (16.9°C).Heat index
September's mean heat index is appraised at a tropical 87.8°F (31°C). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially crucial for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
