Weather in May
Temperature
May's arrival signals a subtle increase in average high-temperatures, moving from April's moderately hot 78.1°F (25.6°C) to a still warm 85.3°F (29.6°C). The average temperature during May nights in Ratcliff is registered at a refreshing 64.4°F (18°C).Heat index
For May, the heat index is computed to be a very hot 95°F (35°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical 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 highly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
