Weather in May
Temperature
The average high-temperature is a still moderately hot 85.1°F (29.5°C) in May, hardly different from the 81.1°F (27.3°C) recorded in April. In the month of May, Saint Francis's average low-temperature falls to a pleasant 68.7°F (20.4°C).Heat index
The heat index value during May is computed to be a torrid 95°F (35°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', quantifies the warmth felt when relative humidity is considered. 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. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
