July, like June, in Palmyra, Missouri, is a moderately hot summer month, with temperature in the range of an average low of 66.9°F (19.4°C) and an average high of 84.7°F (29.3°C).

Temperature

July, with its high-temperature average of 84.7°F (29.3°C) and a low-temperature average of 66.9°F (19.4°C), is the warmest month.

Heat index

The heat index value during July is evaluated at a torrid 96.8°F (36°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
