In
May,
Dhahran starts to feel the full force of summer, with temperatures rising rapidly and the humidity dropping. The hike in temperature compared to the earlier months marks the beginning of the demanding summer season. Dhahran prepares to face the fierce heat of the desert, where average high temperatures soar up to 38.7°C (101.7°F). Rainfall becomes a rarity in this month, leaving the environment dry and arid. As May concludes and
June commences, the weather follows a pattern of escalating temperatures, magnifying the intensity of the heat.
Temperature
The shift from
April to May in Dhahran,
Saudi Arabia, brings an increase in the average high-temperature, moving from a tropical 32.4°C (90.3°F) to a sweltering 38.7°C (101.7°F). The anticipated average low-temperature for May in Dhahran, a warm 24.6°C (76.3°F), shows a substantial deviation from the daytime maximums.
Heat index
Throughout May, the heat index is calculated to be a burning hot 47°C (116.6°F).
Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', shows a temperature sensation when both heat and moisture conditions are combined. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are quite important for babies and toddlers. 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 physiological response of the human body to excess warmth is to perspire, thereby cooling itself through 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. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
Humidity
