Weather in May
Temperature
A minor escalation in the average high-temperature is seen with the onset of May, moving from a moderately hot 78.1°F (25.6°C) in April to a still warm 84.7°F (29.3°C). Cottonwood records a consistent low-temperature of 65.3°F (18.5°C) during May nights.Heat index
For May, the heat index is computed to be a tropical 91.4°F (33°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
