Temperature

The onset of October entails a subtle temperature shift, as the average high-temperature eases from a very hot 38.5°C (101.3°F) in September to a hot 34.3°C (93.7°F). In Al Khobar, the expected average low-temperature for October is a moderately hot 27.9°C (82.2°F).

Heat index

The average heat index in October is computed to be a fiery hot 39°C (102.2°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Note: The daily high UV index of 7 in October translates into this advice:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes. Be careful! The Sun's UV radiation is accentuated by reflecting off sand and water.
