Weather in September
Temperature
September welcomes an average high-temperature of a moderately hot 81.7°F (27.6°C), not much different from the preceding month. Nighttime temperature lowers to an average of 63°F (17.2°C) in September.Heat index
September's heat index is appraised at a tropical 86°F (30°C). With prolonged exposure and constant activity, one might feel exhausted and experience heat cramps.Note that heat index values are valued for light wind and location in the shade. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
