Weather in September
Temperature
A modest decline in the average high-temperature is seen during September, decreasing from a tropical 87.3°F (30.7°C) in August to a warm 81.9°F (27.7°C). During September, the average low-temperature is a comfortable 61.9°F (16.6°C).Heat index
The heat index value during September is estimated at a hot 87.8°F (31°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
