Weather in September
Temperature
The arrival of September sees a recorded average high-temperature of a warm 81.3°F (27.4°C), showing little divergence from the previous month's conditions. Nighttime temperatures throughout September register a significant deviation from the day's highs, averaging at a mild 59.5°F (15.3°C).Heat index
September's mean heat index is estimated at a tropical 86°F (30°C). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
