Weather in September
Temperature
The onset of September entails a subtle temperature shift, as the average high-temperature eases from a tropical 92.5°F (33.6°C) in August to a warm 85.8°F (29.9°C). During the September nights, an average temperature of 64.9°F (18.3°C) is observed.Heat index
Throughout September, the heat index is calculated to be a very hot 95°F (35°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.Realize that the values for the heat index are set for shaded places and light winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Rising body temperatures due to excess heat retention could signify impending heat disorders.
