Weather in September
Temperature
September is characterized by a slight reduction in average high-temperature, easing from 93°F (33.9°C) in August to a still hot 86.5°F (30.3°C). Throughout September, the average low-temperature records at a comfortable 65.7°F (18.7°C).Heat index
For most parts of September, the heat index is evaluated at a sweltering 96.8°F (36°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.For clarity, heat index numbers account for light winds and areas under shade. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
