September weather forecast and climate
Sharjah, United Arab Emirates

September, the first month of the autumn, in Sharjah, is still a very hot month, with average temperature ranging between min 24.3°C (75.7°F) and max 39.8°C (103.6°F).

Temperature

In September, the average high-temperature is relatively the same as in August - a sweltering 39.8°C (103.6°F). In September, in Sharjah, the average low-temperature is 24.3°C (75.7°F).

Heat index

The average heat index is estimated 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 'real feel', 'felt air temperature', 'feels like', or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Additional factors like metabolic differences, wind, clothing, and activity influence one's weather impression. 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. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Humidity

In Sharjah, the average relative humidity is 62%.

Rainfall

June, August through October are months without rainfall in Sharjah, United Arab Emirates.

Sea temperature

In September, the average sea temperature is 33.2°C (91.8°F).
Note: The surface water temperatures above 30°C (86°F) are arguably considered as unpleasant for swimming, and any intense water activity, as the refreshing effect of water is missing.

Daylight

The average length of the day in Sharjah is 12.3h.

Sunshine

The average sunshine in September is 10.2h.

UV index

The average daily maximum UV index in Sharjah, United Arab Emirates, is 11. A UV Index estimate of 11, and higher, represents an excessive health risk from unsafe exposure to the UV radiation for the average person.
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. A wide-brim hat offers excellent sun protection for eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Tightly woven, loose-fitting clothes provide additional protection from the Sun. 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.
