Weather in September
Temperature
With September's onset, the weather reveals a slight temperature decrease, transitioning from a hot 91.4°F (33°C) in August to a moderately hot 82.8°F (28.2°C). Hart's average low-temperature is measured at a comfortable 61.9°F (16.6°C) during September.Heat index
For September, the heat index is evaluated at a tropical 86°F (30°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Know that the heat index computations account for shaded terrains and slight winds. 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 'felt air temperature', 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 swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
