Weather in May
Temperature
The shift from April to May is marked by a slight increase in the average high-temperature, moving from a moderately hot 73.6°F (23.1°C) to a still warm 80.8°F (27.1°C). During the month of May, Oak Grove's nighttime temperature lowers to an average of 62.8°F (17.1°C).Heat index
In May, the average heat index is calculated to be 84.2°F (29°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
