Weather in September
Temperature
The arrival of September brings an average high-temperature of a still fiery hot 35°C (95°F), subtly diverging from August's 37.4°C (99.3°F). With a notable disparity from daily peak temperatures, the average low-temperature settles at a pleasant 22.4°C (72.3°F) throughout September.Heat index
In September, the heat index is computed to be a torrid 39°C (102.2°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Note that heat index values are valued for light wind and location in the shade. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

In September, the average relative humidity is 46%.Rainfall
In Girza, rain does not fall in May through October.Daylight
In September, the average length of the day is 12h and 20min.On the first day of the month, sunrise is at 6:32 am and sunset at 7:17 pm. On the last day of September, sunrise is at 6:48 am and sunset at 6:42 pm EEST.
Sunshine
The average sunshine in September is 11.2h.UV index
In Girza, the average daily maximum UV index in September is 7. A UV Index reading of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for ordinary individuals.Note: A maximum high daily UV index of 7 during September translates into the following directions:
Prevent overexposure. Protection from the sun's harmful effects is needed. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
