Weather in September
Temperature
The arrival of September corresponds with a minor reduction in the average high-temperature, down from August's tropical 93°F (33.9°C) to a moderately hot 84.9°F (29.4°C). Dacoma encounters an average low-temperature of 66.4°F (19.1°C) during September nights.Heat index
During September, the heat index is estimated at a tropical 89.6°F (32°C). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
