May weather forecast
Lul, South Sudan

Arriving in May, Lul witnesses a full-on wet season profile. Rainfall significantly increases, and the atmosphere turns more humid. Clouds start to dominate the sky, reducing sunshine hours and consequently the temperature. The rainfall shoots up to a substantial 38mm (1.5"), making May stand out as the initiation of the heavy rainfall period. Despite the reduced daylight and the sun, the visibility remains unaffected, still providing clear views.

Temperature

May's onset introduces a mild reduction in the average high-temperature, from a blisteringly hot 41.4°C (106.5°F) in April to a fiery hot 36.7°C (98.1°F). Lul experiences a steady low-temperature of 27.7°C (81.9°F) throughout May.

Heat index

For most parts of May, the heat index is appraised at a blisteringly hot 44°C (111.2°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Take extra precautions. Fair-skinned individuals may get burned in less than 10 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
