Weather in May
Temperature
The start of May signals a slight increase in the average high-temperature, moving from a moderately hot 75.4°F (24.1°C) in April to a still warm 83.3°F (28.5°C). Opelika, amidst the high May temperatures, experiences a substantial shift to an average nighttime low of 61.7°F (16.5°C).Heat index
In May, the average heat index is estimated at a hot 89.6°F (32°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.Note that heat index values are valued for light wind and location in the shade. 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', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
