Weather in September
Temperature
In September, the average high-temperature marginally drops from a tropical 91.9°F (33.3°C) in August to a warm 84.7°F (29.3°C). Adams, during September nights, observes an average temperature of 63.9°F (17.7°C).Heat index
For most parts of September, the heat index is appraised at a hot 86°F (30°C). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
