April weather forecast
Kasafoni, Sierra Leone

April marks the beginning of what is traditionally known as the long rainy season in Sierra Leone. This period is characterised by higher rainfall, increased cloud coverage, and a decrease in sunshine hours. The rainfall increases dramatically to an average of 53mm (2.09"). It is the month that sees the welcome transformation from the dry to wet season, with the average humidity rising to 59%, making the overall weather fairly muggy. Despite the frequent rains, the city of Kasafoni continues to hum with activity, as locals adapt to the changing weather conditions.

Temperature

Kasafoni's average high-temperature in April is a still torrid 37°C (98.6°F), marking an insignificant difference from the 38°C (100.4°F) of March. Following the sharp contrast to daytime warmth, an average nighttime temperature of 21.8°C (71.2°F) gets registered during April.

Heat index

Throughout April, the heat index is estimated at a life-threatening hot 51°C (123.8°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Consider that heat index readings are for situations in the shade and light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Humidity

The average relative humidity in April is 59%.

Note: A typical high UV index of 7 in April suggests the following recommendations:
Inhibit overexposure. Warding off sun damage is of utmost importance. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Stay sun-safe with clothing that is both closely woven and worn loosely.
