May weather forecast
Tomena, Burkina Faso

May, the last month of the spring in Tomena, is also a fiery hot month, with an average temperature fluctuating between 37.9°C (100.2°F) and 26.3°C (79.3°F).

Temperature

The transition into May notes an average high-temperature of a still torrid 37.9°C (100.2°F), revealing a mild distinction from the 39.3°C (102.7°F) in April. Throughout the month of May, Tomena expects an average low of 26.3°C (79.3°F).

Heat index

Throughout May, the heat index is calculated to be a life-threatening hot 49°C (120.2°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.
Consider that heat index readings are for situations in the shade and light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. 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 are especially vital to children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

In Tomena, the average relative humidity in May is 51%.

Rainfall

In Tomena, in May, during 11.4 rainfall days, 44mm (1.73") of precipitation is typically accumulated. Throughout the year, there are 129.4 rainfall days, and 491mm (19.33") of precipitation is accumulated.

UV index

February through May, with an average maximum UV index of 8, are months with the highest UV index. A UV Index reading of 8 to 10 represents a very high health hazard from exposure to the Sun's UV radiation for the ordinary person.
Note: A maximum high UV index of 8 in May translates into the following recommendations:
Take all necessary measures. Eyes and skin are at risk if left unprotected. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
