Weather in September

September observes an average high-temperature of a warm 83.1°F (28.4°C), marking an insignificant difference from August's 88°F (31.1°C). The temperature lowers to an average of 63.1°F (17.3°C) during September nights.Heat index
During September, the heat index is appraised at a hot 89.6°F (32°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. 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.
