October weather forecast
Dammam, Saudi Arabia

October signals the beginning of Dammam's autumn with a considerable reduction in temperature. A shift from the searing summer heat, October’s weather is noticeably cooler and more comfortable compared to the preceding months. With mild weather conditions and a sizeable decrease in temperature from September’s 41.4°C (106.5°F) high, the changing season offers a welcome reprieve. As November approaches, expect to see a considerable dip in temperature, with colder days and nights ahead.

Temperature

The arrival of October suggests a slight decrease in the average high-temperature, moving from a scorching 41.4°C (106.5°F) in September to a sweltering 37.6°C (99.7°F). A sharp divergence from daytime highs is noted in Dammam during the month of October, with the average nighttime temperature settling at an agreeable 21.2°C (70.2°F).

Heat index

Throughout October, the heat index is calculated to be a blazing hot 46°C (114.8°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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 natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
