September weather forecast and climate
Sharjah, United Arab Emirates

September, the first month of the autumn, in Sharjah, is also a sweltering month, with temperature in the range of an average low of 24.3°C (75.7°F) and an average high of 39.8°C (103.6°F).

Temperature

In Sharjah, United Arab Emirates, the average high-temperature in September is practically the same as in August - a very hot 39.8°C (103.6°F). In Sharjah, United Arab Emirates, the average low-temperature is 24.3°C (75.7°F).

Heat index

In September, the average heat index is evaluated at a burning hot 63.5°C (146.3°F). These weather conditions are considered as extremely dangerous, as heatstroke is imminent.
Note that heat index values are valued for light wind and location in the shade. With the exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like', 'apparent temperature', 'felt air temperature', or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. This effect is individual, with diverse people perceiving weather differently for numerous reasons (wind, pregnancy, clothing), and activity. Be aware that direct exposure to sunlight increases heat impact, and may raise the heat index additionally, by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it is vital to remain hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 37.5°C (99.5°F) to 38.3°C (100.9°F), thermal conditions are potentially life-threatening.

In Sharjah rain does not fall in June, August through October.

Sea temperature

Sunshine

In Sharjah, United Arab Emirates, the average sunshine in September is 10.2h.

UV index

In September, the average daily maximum UV index is 11. A UV Index value of 11, and more, symbolizes an extreme health hazard from unprotected exposure to the Sun's UV rays for ordinary individuals.
Note: In September, the average maximum UV index of 11 translate into the following recommendations:
Practice all-important precautions. Light skin people may get burned in less than 5 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. Even on cloudy days, a sunscreen with a minimum 30 sun protection factor should be generously applied and frequently re-applied, including after every swim or outdoor exercise. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.
