Weather in May
Temperature
As May arrives, a slight rise in the average high-temperature is observed, moving from 78.4°F (25.8°C) in April to a still warm 85.1°F (29.5°C). Killian encounters an average low-temperature of 65.8°F (18.8°C) during May nights.Heat index
For most parts of May, the heat index is computed to be a torrid 95°F (35°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially crucial for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
