Weather in September

As September takes hold, the average high-temperature is a still moderately hot 27.7°C (81.9°F), nearly mirroring that of the previous month. Nighttime temperatures record an average of 26.5°C (79.7°F) throughout September.Heat index
For September, the heat index is calculated to be a hot 31°C (87.8°F). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
