May weather forecast
Rowal, Sierra Leone

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

Temperature

May brings an average high-temperature of a still hot 30.7°C (87.3°F), showing a slight difference from April's 30.8°C (87.4°F). A modest decline from daytime high temperatures is noticed in May, marking the average low at a warm 26.2°C (79.2°F).

Heat index

May's heat index is computed to be a very hot 39°C (102.2°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Humidity

In May, the average relative humidity is 78%.

Note: The UV index of 7 during May translates into the following guidance:
Resist overexposure. Safeguarding from solar damage is indispensable. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
