May weather forecast
Yana, Sierra Leone

Yana steps into full-blown wet season transition in May. The temperatures decrease slightly compared to previous monthe - April, yet the humidity levels soar. A stark contrast to the dry conditions of the initial months of the year, a marked increase in rainfall characterizes May. With a notable rise in precipitation from 29mm (1.14") in April to 127mm (5"), Yana experiences frequent downpours. Despite the surge in rainfall, a careful eye on weather forecasts can allow for sightings of local attractions between showers.

Temperature

May ushers in a minute temperature change, with average high-temperatures reducing from April's torrid 39°C (102.2°F) to a still fiery hot 35.2°C (95.4°F). Despite the significant gap from daytime peaks, Yana experiences an average low-temperature of 22.8°C (73°F) in May.

Heat index

In May, the heat index is appraised at a life-threatening hot 51°C (123.8°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
