April weather forecast
Yumbi, Democratic Republic of Congo

April, the same as March, in Yumbi, Democratic Republic of Congo, is another hot autumn month, with an average temperature fluctuating between 31.8°C (89.2°F) and 23°C (73.4°F).

Temperature

The onset of April brings with it an average high-temperature of a still hot 31.8°C (89.2°F), showing a negligible variation from the month before. During April, Yumbi sees a mean low-temperature of 23°C (73.4°F).

Heat index

For most parts of April, the heat index is computed to be a blisteringly hot 42°C (107.6°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. 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. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Humidity

In April, the average relative humidity is 76%.

UV index

January through August, October through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for the ordinary person.
Note: The daily high UV index of 7 in April translates into this advice:
Adhere to precautions and respect sun safety doctrines. Avoiding sunburn is vital. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
