Weather in September

The average high-temperature during September is a moderately hot 81.9°F (27.7°C), almost matching the conditions of the preceding month. Throughout September, the average low-temperature records at a refreshing 62.4°F (16.9°C).Heat index
In September, the heat index is computed to be a hot 86°F (30°C). Long-standing exposure and activity could induce a feeling of tiredness and lead to heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
