Weather in May
Temperature
In May, the meteorological conditions subtly change with the average high-temperature edging from a warm 73.9°F (23.3°C) in April to a still moderately hot 81.9°F (27.7°C). McCalla, in May, witnesses an average low-temperature of 61.2°F (16.2°C).Heat index
In May, the average heat index is evaluated at a hot 86°F (30°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.One should consider that heat index numbers are for shaded settings and light wind. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.

Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
