Weather in September
Temperature
September brings a minor shift in the average high-temperature, adjusting from a fiery hot 95.7°F (35.4°C) in August to a tropical 88.5°F (31.4°C). September sees the temperature falling to a mean low of 70.5°F (21.4°C).Heat index
The heat index for September is computed to be a fiery hot 100.4°F (38°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
