Weather in May
Temperature
The shift into May is characterized by a subtle rise in the average high-temperature, transitioning from April's agreeable 73.2°F (22.9°C) to a warm 81.1°F (27.3°C). Fairs Crossroads, during May, witnesses an average low-temperature of 60.4°F (15.8°C).Heat index
The heat index value during May is estimated at a hot 86°F (30°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Heat index determinations are made taking into account the shade and light air movements. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
