Weather in May
Temperature
As May sets, the average high-temperature shows a slight increase, moving up from a warm 81.1°F (27.3°C) in April to a hot 87.3°F (30.7°C). Devine sees an average low-temperature of 67.6°F (19.8°C) during May.Heat index
The heat index in May is computed to be a fiery hot 98.6°F (37°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
