Weather in September
Temperature
In Nineveh, entering September brings a subtle temperature decrement, reducing from August's torrid 95.9°F (35.5°C) to a tropical 88.7°F (31.5°C). Nineveh reports a consistent average low-temperature of 68.9°F (20.5°C) throughout September nights.Heat index
For most parts of September, the heat index is calculated to be a torrid 102.2°F (39°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
