Weather in May

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.

The average relative humidity in May is 78%.
