Weather in September
Temperature
September's onset records a minor alteration in the average high-temperature to a still hot 87.1°F (30.6°C) from August's 90.5°F (32.5°C). In September, the recorded average low-temperature is an agreeable 68.4°F (20.2°C).Heat index
For most parts of September, the heat index is appraised at a torrid 102.2°F (39°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
