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

The advent of May brings a slight shift in average high-temperature, moving from a blistering 41.4°C (106.5°F) in April to a sweltering 36.7°C (98.1°F). During May, an average low-temperature of 27.7°C (81.9°F) is observed.

Heat index

In May, the average heat index is evaluated at a blisteringly hot 44°C (111.2°F). Mind: Heat cramps along with heat exhaustion are anticipated. Heatstroke can develop with continued physical activity.
The standards for the heat index are set for locations in shade and under light breezes. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Humidity

In Lul, the average relative humidity in May is 48%.

Always take safety measures. The skin and eyes are at risk if left exposed. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
