Besides increased precipitation and humidity, the relative pressure depicts a notable rise as we transition from March to April. The days are warm but bearable, with slight relief experienced during nights. The city gets caught up in rain almost every other day, causing the surrounding landscapes to display a lush green. Hot winds prevailing this month mark only the beginning of a season known for its scorching sun.

Temperature

The arrival of April sees an average high-temperature of a still tropical 30.6°C (87.1°F), hardly diverging from March's 32.2°C (90°F). Mambasa documents a substantial deviation from daytime highs with a consistent low-temperature of 18.4°C (65.1°F) during April nights.

Heat index

The heat index value for April is computed to be a fiery hot 39°C (102.2°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Humidity

In April, the average relative humidity is 79%.

Note: A maximum high daily UV index of 6 during April translates into the following directions:
Prevent overexposure. Protection from the sun's harmful effects is needed. 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 holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
