March weather forecast
Jeddah, Saudi Arabia

As the year progresses, March brings further warming temperatures to Jeddah, though maintaining the same relative humidity at 60%. This month notices the most dramatic temperature rise with temperatures soaring up to 31.8°C (89.2°F). The increment in the daylight implies an augmentation in sunshine hours, which in turn contributes to a higher UV index. On moving towards April, anticipate later sunsets and hotter temperatures in Jeddah.

Temperature

Jeddah registers an average high-temperature of a hot 31.8°C (89.2°F) with the arrival of March, showing minor deviation from the preceding month. During March, Jeddah's temperature averages to a pleasant 21.4°C (70.5°F) at night.

Heat index

March's average heat index is estimated at a very hot 37°C (98.6°F). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Ensure all key precautions. Defense against sun exposure is critical. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Boost your sun resistance with garments that are densely woven yet spacious. Even on a cloudy day, sunscreen with a minimum SPF of 30 should be used liberally and reapplied often, especially after a swim or outdoor activity. Take caution! The UV rays from the Sun gain strength from sand and water reflections.
