Weather in May
Temperature
A slight uplift of average high-temperatures is noted in May, with temperatures adjusting from a warm 77.5°F (25.3°C) in April to a still moderately hot 84.7°F (29.3°C). The nights of May in Henderson anticipate an average low-temperature of 66.7°F (19.3°C).Heat index
The heat index value during May is calculated to be a very hot 95°F (35°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
