May weather forecast
Koidu, Sierra Leone

May bears the hallmarks of a typical wet season in Koidu, distinguished by the highest rainfall recorded in the year at 166mm (6.54"). Accompanying the substantial rainfall, the city also witnesses a spike in humidity levels. The severely limited sunshine, paired with increased cloud coverage, augments the moist conditions. The decrease in wind speed also means there is lesser relief from the damp weather. A similar weather trend transcends into June, ensuring the continuation of the wet spells.

Temperature

Koidu's transition from April to May introduces an average high-temperature of a still tropical 32.1°C (89.8°F), marking an insignificant variation from the 34.8°C (94.6°F). During May, Koidu sees a mean low-temperature of 21.9°C (71.4°F).

Heat index

May's average heat index is evaluated at a blazing hot 47°C (116.6°F). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

UV index

In Koidu, the average daily maximum UV index in May is 6. A UV Index value of 6 to 7 symbolizes a high health risk from unprotected exposure to Sun's UV rays for the average person.
Note: During May, 6 as the daily maximum UV index converts into the following advice:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
