August, the last month of the summer in Lexington, is another hot month, with temperature in the range of an average low of 68.7°F (20.4°C) and an average high of 88.2°F (31.2°C).

The arrival of August coincides with an average high-temperature of a still hot 88.2°F (31.2°C), indicating a minimal shift from July's 89.1°F (31.7°C). During August, the average low-temperature is a pleasant 68.7°F (20.4°C).

Heat index

Throughout August, the heat index is computed to be a scorching 104°F (40°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
