Weather in September
Temperature
The transition to September results in a modest reduction in average high-temperature, moving from a tropical 92.5°F (33.6°C) in August to a warm 85.3°F (29.6°C). Walls logs a notable disparity from the daily highs during September, as the nighttime temperature lowers to an average of 63.5°F (17.5°C).Heat index
September's average heat index is computed to be a hot 93.2°F (34°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
