Weather in September

The heat index value for September is calculated to be a hot 89.6°F (32°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. 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.
