September signals a slight drop in average high-temperature, sliding from August's hot 86°F (30°C) to a moderately hot 80.6°F (27°C). Catlen, in September, witnesses an average low-temperature of 60.4°F (15.8°C).Heat index
September's average heat index is appraised at 84.2°F (29°C). Exhaustion is likely with prolonged exposure and activity. Sustaining activity may result in heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight can cause a surge in the heat index 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 including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
