Weather in May
Temperature
The arrival of May introduces a minor uplift in high-temperatures, adjusting from 73.4°F (23°C) in April to a still moderately hot 81.1°F (27.3°C). Napoleon experiences a nighttime temperature average of 60.4°F (15.8°C) during May.Heat index
May's average heat index is calculated to be a tropical 86°F (30°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
