July weather forecast
Lebanon, TN

July in Lebanon, Tennessee witnesses the pinnacle of summer heat, as it records the highest maximum average temperature of the year at 87.4°F (30.8°C). This maximum temperature anomaly makes July the hottest month of the year, outperforming both June and August. A consistent feature of the weather is high humidity, which attributes a humid subtropical feel to the summer. Relief from the summer heat is within reach as August brings a slight dip in temperatures. The scattered summer showers of July compensate for the intense heat, a precursor to the slightly enhanced rainfall in August.

July registers as the month with the highest average temperatures, reaching 87.4°F (30.8°C) at its peak and 68.2°F (20.1°C) at the lowest.

Heat index

The heat index for July is computed to be a torrid 102.2°F (39°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
For clarity, heat index numbers account for light winds and areas under shade. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including 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 extremely significant for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by 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. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
