Weather in September
Temperature
September's weather records an average high-temperature of a still hot 87.3°F (30.7°C), showing little deviation from August. Throughout September, a steady low-temperature average of 67.5°F (19.7°C) is noted.Heat index
September's mean heat index is appraised at a torrid 100.4°F (38°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
