May, immersed fully into the wet season, presents a new side to
Juba's typical hot and sunny weather. The rains continue to grace Juba, yet the city holds onto its tropical heart with persistent high temperatures. The average rainfall continues its upward trend, now at a hefty 130mm (5.12"). Despite this, it should not be assumed that the sun shy away entirely. The showers, although frequent, are shared with periods of sunshine, preserving the overall warm feel of Juba.

Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.
Consider that heat index readings are for situations in the shade and light wind. 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 'real feel' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. 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 quite important for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Undertake all key precautions, as unprotected skin and eyes may get burns in no time. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage. Despite the clouds, sunscreen with an SPF of at least 30 should be used liberally and reapplied frequently, especially after a swim or outdoor workout.
