Weather in September
Temperature
In the transition to September, Avant observes a minor drop in the average high-temperature, shifting from a tropical 90.1°F (32.3°C) in August to a moderately hot 83.3°F (28.5°C). Avant observes an average low-temperature of 63.7°F (17.6°C) during September nights.Heat index
Throughout September, the heat index is computed to be a hot 89.6°F (32°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially crucial for babies and toddlers. 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.
