Weather in September
Temperature
September commences with an average high-temperature of a still hot 87.8°F (31°C), showing little deviation from August's 91.6°F (33.1°C). During September, the average low-temperature is recorded at a pleasant 68.9°F (20.5°C).Heat index
In September, the heat index is evaluated at an extremely hot 105.8°F (41°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.For clarity, heat index numbers account for light winds and areas under shade. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
