Weather in September
Temperature
In September, Nafhan experiences a minor shift in meteorological conditions with average high-temperatures marked at a still sweltering 35.8°C (96.4°F), closely mirroring the climate in August. Nafhan nights in September witness a mild cool down to an average temperature of 31.1°C (88°F).Heat index
September's average heat index is computed to be a burning hot 48°C (118.4°F). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. 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.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. 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. As body temperatures escalate without effective heat release, one might face dehydration threats.

Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
