Weather in September
Temperature
The advent of September brings a subtle shift in temperature, with the average high moving from a hot 92.5°F (33.6°C) in August to a warm 85.8°F (29.9°C). During September, the nighttime temperature averages of 64.9°F (18.3°C).Heat index
The heat index for September is computed to be a very hot 95°F (35°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
