Weather in September
Temperature
The transition into September notes an average high-temperature of a still hot 87.8°F (31°C), revealing a mild distinction from the 92.5°F (33.6°C) in August. During September, the nighttime temperature averages to a refreshing 67.8°F (19.9°C).Heat index
The average heat index in September is appraised at a fiery hot 100.4°F (38°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. 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 'feels like', determines the feeling of heat when you account for the relative humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
