Weather in September
Temperature
The warmest temperatures occur during September, when averages reach a peak of 36.6°C (97.9°F) and a low of 23.5°C (74.3°F).Heat index
During September, the heat index is calculated to be a blisteringly hot 43°C (109.4°F). Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.In terms of the heat index, values are set with light wind and shade conditions in mind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
