September weather forecast
Farasan, Saudi Arabia

September signifies the commencement of a gradual cooling phase in Farasan as temperatures begin to subside from their peak. Nonetheless, September hasn't fully shrugged off summer characteristics, maintaining the sea temperature at a constant 32°C (89.6°F) for the third consecutive month. This period sees a significant fall in rainfall, making it one of the driest months of the year. A very slight reduction in daylight hours indicates the approach of the year's latter months. In essence, the weather of September provides a blend of summer and autumn characteristics.

Temperature

The commencement of September is characterized by an average high temperature of a still hot 34.5°C (94.1°F), bearing no significant change from August. Farasan's nighttime temperatures in September display a slight drop from daytime highs, averaging to a still tropical 30.8°C (87.4°F).

Heat index

The average heat index in September is computed to be a life-threatening hot 47°C (116.6°F). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.
The metrics for the heat index are tailored for both shady environments and light winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Humidity

In September, the average relative humidity in Farasan, Saudi Arabia, is 68%.

Rainfall

In Farasan, during September, the rain falls for 2.3 days and regularly aggregates up to 2mm (0.08") of precipitation. Throughout the year, there are 63.5 rainfall days, and 160mm (6.3") of precipitation is accumulated.

Sea temperature

July through September, with an average sea temperature of 32°C (89.6°F), are months with the warmest seawater.
Note: The ideal feeling of cooling down in water can be lost when the temperature surpasses 30°C (86°F).

Daylight

In Farasan, the average length of the day in September is 12h and 14min.
On the first day of September in Farasan, sunrise is at 05:58 and sunset at 18:24. On the last day of the month, sunrise is at 06:01 and sunset at 18:01 +03.

Sunshine

In September, the average sunshine is 11.9h.

UV index

The months with the highest UV index are April through October, with an average maximum UV index of 8. A UV Index estimate of 8 to 10 represents a very high health hazard from exposure to the Sun's UV rays for ordinary individuals.
Note: The UV index of 8 during September translates into the following guidance:
Take special precautions, as unprotected skin can be damaged and can burn quickly. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Stay sun-safe with clothing that is both closely woven and worn loosely. Warning! The reflection of sand and water increases the UV dose.
