Weather in September
Temperature
September brings an average high-temperature of a warm 82.2°F (27.9°C), showing a slight difference from August's 86.5°F (30.3°C). An average low-temperature of 63.7°F (17.6°C) is anticipated throughout the nights during September.Heat index
September's average heat index is estimated at a tropical 87.8°F (31°C). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.Note that heat index values are valued for light wind and location in the shade. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
