Temperature
The shift from
October to November in Jeddah includes a minor decrease in the average high-temperature, lightly dropping from a sweltering 36.7°C (98.1°F) to a tropical 33.5°C (92.3°F). Jeddah, during November, witnesses an average low-temperature of 22.3°C (72.1°F).
Heat index
The heat index for November is estimated at an extremely hot 43°C (109.4°F).
Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.
Heat index determinations are made taking into account the shade and light air movements. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
Humidity
The average relative humidity in November is 65%.
Rainfall
November is the month with the most rainfall. Rain falls for 1 days and accumulates 26mm (1.02") of precipitation.

Note: A daily maximum UV index of 7 in November translates into the following instructions:
Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat. Warning! Reflective surfaces like sand and water amplify the Sun's UV radiation.
