Weather in May
Temperature
May's arrival is noted with a slight increase in the average high-temperature, moving from a moderately hot 80.1°F (26.7°C) in April to a tropical 86°F (30°C). Throughout the May nights, Hilliard encounters a low-temperature of 66.4°F (19.1°C).Heat index
In May, the average heat index is appraised at a fiery hot 95°F (35°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Fend off overexposure. Sun protection is vital. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
