Weather in September
Temperature
The transition into September involves a small decrease in the average high-temperature, dipping slightly from a fiery hot 95.9°F (35.5°C) in August to a tropical 87.6°F (30.9°C). An average nighttime temperature of 69.6°F (20.9°C) is noted during the month of September.Heat index
The heat index for September is computed to be a sweltering 95°F (35°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
