Weather in May
Temperature
The average high-temperature mildly increases in May, edging from a warm 77.5°F (25.3°C) in April to a still moderately hot 84.6°F (29.2°C). Jackson, in the month of May, anticipates a consistent average low-temperature of 64.6°F (18.1°C).Heat index
May's heat index is evaluated at a sweltering 95°F (35°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Observations indicate that the heat index values are for shady locations with light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
