April weather forecast
Wilberforce, Sierra Leone

The peak of the dry season in Wilberforce, Sierra Leone, is at hand by April. A marked increase in rainfall to 18mm (0.71") and a significant rise in relative humidity are the distinctive features of this month. The increase in precipitation contrasts significantly with the low levels of rainfall observed from January to March. There's a corresponding rise in cloud coverage, and this along with more prominent winds contributes to a reduction in visibility as compared to the prior months. On the other hand, temperatures remain reasonably warm, with adequate daylight and sunshine hours making the weather favorable.

Temperature

With the onset of April, Wilberforce'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 low-temperature of 25.3°C (77.5°F) is common during the nights of April.

Heat index

April's heat index is computed to be a fiery hot 38°C (100.4°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
