October weather forecast
Jeddah, Saudi Arabia

The warm autumn glow graces Jeddah in October, providing relief from the scorched summer months. The weather conditions remain dry yet comfortable, characterized by a slow and steady decrease in daytime temperatures. Restful temperatures soon dominate, offering perfect opportunities for visitors and residents to enjoy outdoor activities. Moving into November, further reductions in temperatures set the stage for the approaching winter season.

Temperature

October in Jeddah experiences an average high-temperature of a still torrid 36.7°C (98.1°F), barely different from September's 37.6°C (99.7°F). Contrary to the day's heat, an average low-temperature of 24.1°C (75.4°F) is recorded during the nights in October in Jeddah, Saudi Arabia.

Heat index

October's average heat index is estimated at a blazing hot 54°C (129.2°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Be sure to take precautions. Without protection, skin might suffer damage quickly. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting 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. After a swim or an outdoor workout, generously apply and regularly reapply a sunscreen with at least SPF 30, even if the day is cloudy. Heads up! Sand and water reflection magnifies the UV exposure from the Sun.
