Weather in September
Temperature
September indicates a minor shift in the average high-temperature, from August's hot 92.8°F (33.8°C) to a warm 84.7°F (29.3°C). Throughout the month of September, the average temperature dips to an enjoyable 65.5°F (18.6°C) at night.Heat index
September's heat index is calculated to be a tropical 89.6°F (32°C). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
