Weather in September
Temperature
The arrival of September corresponds with a minor reduction in the average high-temperature, down from August's tropical 93.7°F (34.3°C) to a warm 84.9°F (29.4°C). In the month of September, the average temperature dips to a comfortable 66.2°F (19°C) during the night.Heat index
The heat index value for September is calculated to be a hot 87.8°F (31°C). Constant activity during exposure could result in a state of weariness and possibly heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
