Weather in May
Temperature
May's arrival signals a subtle increase in average high-temperatures, moving from April's warm 78.1°F (25.6°C) to a still moderately hot 85.3°F (29.6°C). May nights are marked by an average low-temperature of 64.9°F (18.3°C).Heat index
The average heat index in May is appraised at a sweltering 96.8°F (36°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
