Weather in May
Temperature
With the onset of May, Richmond observes a minor temperature ascent, with the average high-temperature adjusting from April's 78.4°F (25.8°C) to a still warm 85.3°F (29.6°C). May brings with it a nighttime average temperature of 68°F (20°C).Heat index
For May, the heat index is calculated to be a fiery hot 96.8°F (36°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
