The commencement of May records an average high-temperature of a tropical 86.5°F (30.3°C), barely varying from April's 82.4°F (28°C). During May, Harney consistently records a temperature low averaging a pleasant 70°F (21.1°C).

Heat index

For most parts of May, the heat index is estimated at a very hot 96.8°F (36°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through 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. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
