Weather in July

July, the same as June, is another warm summer month in Princeton, Missouri, with an average temperature fluctuating between 84.4°F (29.1°C) and 66.7°F (19.3°C).

Temperature

July registers as the month with the highest average temperatures, reaching 84.4°F (29.1°C) at its peak and 66.7°F (19.3°C) at the lowest.

Heat index

Throughout July, the heat index is appraised at a very hot 95°F (35°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
