Weather in May
Temperature
May brings a slight rise in Winchester's average high-temperature, moving from 78.4°F (25.8°C) in April to a still moderately hot 85.6°F (29.8°C). Winchester observes an average nighttime low-temperature of 65.7°F (18.7°C) during the month of May.Heat index
During May, the heat index is calculated to be a very hot 96.8°F (36°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
