May, the last month of the spring in Arlington, is also a moderately hot month, with temperature in the range of an average high of 85.3°F (29.6°C) and an average low of 66°F (18.9°C).

The shift from April to May is marked by a slight increase in the average high-temperature, moving from a warm 78.4°F (25.8°C) to a still moderately hot 85.3°F (29.6°C). The temperature lowers to an average of 66°F (18.9°C) during May nights.

Heat index

For May, the heat index is calculated to be a torrid 95°F (35°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.
In terms of the heat index, values are set with light wind and shade conditions in mind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
