September nights see a notable contrast from daytime highs, with the nighttime temperature averaging at a moderate 60.4°F (15.8°C).Heat index
September's heat index is evaluated at a tropical 87.8°F (31°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.Observations indicate that the heat index values are for shady locations with light wind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
