Weather in September
Temperature
September witnesses a gentle descent in average high-temperature, descending from August's fiery hot 95.9°F (35.5°C) to a tropical 87.4°F (30.8°C). An average low-temperature of 70.2°F (21.2°C) is common during the nights of September.Heat index
In September, the heat index is estimated at a torrid 95°F (35°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. 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.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
