Weather in September
Temperature
The beginning of September brings a minor change in the average high-temperature, shifting from a hot 90.7°F (32.6°C) in August to a moderately hot 83.7°F (28.7°C). Marked by a significant temperature drop from daytime highs, the average nighttime temperature lowers to an enjoyable 61.7°F (16.5°C) throughout September.Heat index
September's heat index is estimated at a tropical 91.4°F (33°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
