May weather forecast
Freetown, Sierra Leone

As Freetown steps into May, the city's weather takes on a thoroughly wet character. Temperatures cool slightly, but high humidity could make it feel more intense. There is also a significant jump in rainfall, turning the city distinctly rainier. An increase in cloud cover diminishes the sunlight hours substantially, creating a gloomier environment throughout this month. However, what particularly stands out in May is the exceptional increase in rainfall, accumulating at a whopping 66mm (2.6"), enhancing the essence of the wet season.

Temperature

May in Freetown brings an average high-temperature of a still hot 30.7°C (87.3°F), nearly identical to the preceding month. Freetown's nocturnal average in May closely mirrors its daytime temperatures, settling 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). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Humidity

The average relative humidity in May is 78%.

UV index

The months with the highest UV index are January through June, September through December, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high threat to health from unsafe exposure to UV radiation for the ordinary person.
Note: The UV index of 7 during May leads to these advisories:
Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage. Be alert! The reflection of water and sand augments UV radiation intensity.
