Weather in May
Temperature
A minor escalation in the average high-temperature is seen in Marietta with the onset of May, moving from a pleasant 72.5°F (22.5°C) in April to a warm 80.8°F (27.1°C). An average low-temperature of 61.2°F (16.2°C) is recorded during the nights in May.Heat index
The heat index value during May is calculated to be 84.2°F (29°C). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
