August carries the traits of the preceding month, with persistent rainfall and high humidity. The consistent moist weather pattern remains the mainstay as the month records 128mm (5.04") of rainfall. On this backdrop, the UV index rises, reclaiming its usual high, indicating clear skies on sunny days. A significant continuity with
July lies in the humidity and the comparatively lower sunshine hours. The temperatures, however, bear a tropical mark, with August bringing no break from
Juba's heated characteristics.
Temperature
Juba's shift from July to August is accompanied by an average high-temperature of a still hot 31.6°C (88.9°F), a slight deviation from 31.1°C (88°F). Juba, in August, experiences an average temperature of 21°C (69.8°F) at night.
Heat index
The heat index for August is evaluated at an extremely hot 43°C (109.4°F).
Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Utilize every vital safety procedure. Individuals with light skin may endure burns in less than 5 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance. Every two hours, apply and reapply an SPF 30+ broad-spectrum sunscreen, especially after swimming or engaging in outdoor activities.
