Weather in May

In contrast to the preceding months, May in Yonibana, Sierra Leone sees weather that could be termed as excessively rainy. More significant changes become apparent in May, marking the middle of the rainy season. There's a noticeable drop in the average high temperature down to 34.3°C (93.7°F), coupled with an uptick in humidity up to 79%. May is the departure point from the consistent temperature and sun-filled days of the previous months, leading into a cooler, wetter period. It's a month of transitioning extremes, both in terms of temperature and precipitation.

Temperature

With May's onset, the weather reveals a slight temperature decrease, transitioning from a fiery hot 37.5°C (99.5°F) in April to a hot 34.3°C (93.7°F). In Yonibana, in May, the average low-temperature is a warm 23.8°C (74.8°F).

Heat index

May's heat index is calculated to be a blazing hot 53°C (127.4°F). Warning: Heat cramps and heat exhaustion are anticipated. Heatstroke is a risk with ongoing activity.
Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

In Yonibana, the average relative humidity in May is 79%.

UV index

The months with the highest UV index are January through May, November and December, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for the average person.
Note: In May, the maximum UV index of 7 suggests this advice:
Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
