Temperature

With the onset of April, Dibia's average high-temperature clocks in at a still hot 30.8°C (87.4°F), showing a minor fluctuation from the previous month. An average nighttime temperature of 25.3°C (77.5°F) is witnessed throughout April.

Heat index

During April, the heat index is computed to be a torrid 38°C (100.4°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. 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 'apparent temperature' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Humidity

The average relative humidity in April is 74%.

Rainfall

In April, the rain falls for 9.7 days. Throughout April, 18mm (0.71") of precipitation is accumulated. Throughout the year, there are 205.9 rainfall days, and 1507mm (59.33") of precipitation is accumulated.

UV index

The months with the highest UV index in Dibia, Sierra Leone, are January through June, September through December, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV rays for average individuals.
Note: The maximum daily UV index of 7 in April interprets into the following recommendations:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
