Weather in May
Temperature
May brings a slight rise in Ridgeland's average high-temperature, moving from a warm 75.7°F (24.3°C) in April to a still moderately hot 82°F (27.8°C). An average nighttime temperature of 65.3°F (18.5°C) is witnessed throughout May.Heat index
For most parts of May, the heat index is calculated to be a tropical 87.8°F (31°C). One might feel worn out with persistent exposure and activity, resulting in heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. 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.
