Weather in September
Temperature
September's arrival subtly correlates with a reduction in the average high-temperature, down from a tropical 90.5°F (32.5°C) in August to a moderately hot 85.1°F (29.5°C). September nights showcase a dramatic shift from daytime highs to an average temperature of 56.5°F (13.6°C).Heat index
The heat index value for September is calculated to be 84.2°F (29°C). Persistent activity under exposure might lead to a feeling of weariness, with subsequent heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
