Weather in September
Temperature
The initiation of September sees an average high-temperature of a still moderately hot 27.3°C (81.1°F), showing minor variations from the previous month. During the September nights, an average temperature of 15.8°C (60.4°F) is observed.Heat index
The heat index value during September is calculated to be 28°C (82.4°F). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Records show heat index calculations are tailored for shaded regions and mild winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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.

Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest.
