Weather in September
Temperature
The beginning of September subtly marks a decrease in the average high-temperature, transitioning from a hot 90.9°F (32.7°C) in August to a warm 84.4°F (29.1°C). Perry's temperature in September lowers to a consistent average of 63°F (17.2°C) during the nights.Heat index
During September, the heat index is estimated at a hot 93.2°F (34°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
