Weather in May
Temperature
The start of May signals a slight increase in the average high-temperature, moving from a moderately hot 77.5°F (25.3°C) in April to a still warm 84.6°F (29.2°C). Throughout the month of May, Lafayette observes an average nighttime temperature of 67.5°F (19.7°C).Heat index
In May, the average heat index is evaluated at a hot 93.2°F (34°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
