Weather in September
Temperature

The heat index for September is appraised at a sweltering 98.6°F (37°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Heat index readings emphasize conditions of light breezes and shaded spots. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
