Weather in May
Temperature
The start of May signals a slight increase in the average high-temperature, moving from 76.1°F (24.5°C) in April to a still warm 83.8°F (28.8°C). During May, Pearl experiences a consistent low-temperature average of 63.1°F (17.3°C).Heat index
May's mean heat index is estimated at a hot 91.4°F (33°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.One should consider that heat index numbers are for shaded settings and light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.

The average daily maximum UV index in May is 6. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for the average person.Note: In May, a daily maximum UV index of 6 leads to the following instructions:
Shun overexposure. Protection from sun ravages is indispensable. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
