The coming of May brings a minor shift in Stafford's weather, with average high-temperatures adjusting from April's 78.8°F (26°C) to a still moderately hot 85.6°F (29.8°C). Stafford observes an average low-temperature of 69.3°F (20.7°C) during May nights.

Heat index

For most parts of May, the heat index is calculated to be a fiery hot 96.8°F (36°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
For clarity, heat index numbers account for light winds and areas under shade. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
