May weather forecast
Mount Aureol, Sierra Leone

The last month of the spring, May, is another tropical month in Mount Aureol, Sierra Leone, with an average temperature varying between 30.7°C (87.3°F) and 26.2°C (79.2°F).

Temperature

The start of May marks an average high-temperature of a still tropical 30.7°C (87.3°F), hardly distinguishable from the conditions in April. The low temperature average during May reflects a slight decrease to a moderately hot 26.2°C (79.2°F) from the day's peak.

Heat index

The heat index for May is estimated at a torrid 39°C (102.2°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. 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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Humidity

The average relative humidity in May is 78%.

Rainfall

In Mount Aureol, Sierra Leone, during May, the rain falls for 19.6 days and regularly aggregates up to 66mm (2.6") of precipitation. 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 Mount Aureol 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 threat to health from unsafe exposure to UV radiation for the average person.
Note: The maximum UV index of 7 during May leads to these instructions:
Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
