May weather forecast
Banfora, Burkina Faso

In May, Banfora steps fully into the rainy season, with a sharp spike in both rainfall and relative humidity. The rainfall reaches its first peak of the year at 51mm (2.01"), a marked increase from the 40mm (1.57") recorded in April. Outdoor activities might be slightly interrupted, but the indoor scenes provide equally fantastic experiences, providing a blend of culture, history, and local cuisine. The increase in rainfall does not dissuade visitors from coming to Banfora, as the city enters one of its vibrant periods. Compared to the even rainier month of June, May serves as a taste of the major rainy season that lies ahead.

Temperature

With the arrival of May, Banfora's average high-temperature registers at a still torrid 37.5°C (99.5°F), indicating a subtle variation from the previous month. An average nighttime temperature of 26°C (78.8°F) is witnessed throughout May.

Heat index

For most parts of May, the heat index is estimated at a blazing hot 48°C (118.4°F). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

In May, the average relative humidity is 51%.

UV index

March through May, with an average maximum UV index of 8, are months with the highest UV index. A UV Index estimate of 8 to 10 represents a very high threat to health from exposure to the Sun's UV radiation for average individuals.
Note: An average UV index of 8 in May transforms into this advice:
Always be careful, as unprotected skin and eyes might burn in no time. 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. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
