October weather forecast
Dhahran, Saudi Arabia

October welcomes relatively cooler and comfortable weather conditions to Dhahran. The drop in daytime temperatures signals the onset of the city’s cooling period. A significant decrease in temperature creates a much more agreeable climate compared to the harsh summer months. The insignificant amount of rainfall remains static, and the desert continues to be dry and arid. As October gives way to November, one can anticipate further lowering of temperatures and an increase in general comfort levels.

Temperature

The arrival of October in Dhahran correlates with a minor temperature reduction, down from September's blistering 40.3°C (104.5°F) to a torrid 35.6°C (96.1°F). In October, a remarkable difference from daytime highs is noted, as Dhahran records an average temperature of 22°C (71.6°F) during the night.

Heat index

In October, the average heat index is calculated to be a blazing hot 47°C (116.6°F). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
