Weather in September
Temperature
September brings a slight decrease in temperature, down from a hot 86.7°F (30.4°C) in August to a moderately hot 81.3°F (27.4°C). During the month of September, Shacklett anticipates a mean low-temperature of 61.7°F (16.5°C).Heat index
September's heat index is computed to be a tropical 86°F (30°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
