Weather in September
Temperature
With the beginning of September, the average high-temperature shows a small decrease, transitioning from 94.6°F (34.8°C) in August to a still hot 87.1°F (30.6°C). During the nights in September, an average low-temperature of 69.3°F (20.7°C) is observed.Heat index
Throughout September, the heat index is estimated at a sweltering 95°F (35°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. 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 'real feel' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
