Weather in September
Temperature

In September, the average heat index is computed to be a hot 89.6°F (32°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.The standards for the heat index are set for locations in shade and under light breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
