While July holds the record for the highest temperatures ever recorded in the state, August is not far behind. In regions like Louisville and Lexington, residents brace for another month of oppressive heat and high humidity. These urban areas can sometimes experience the "heat island" effect, which makes them even hotter than rural locales.

When juxtaposed with September, August serves as a bridge month. While the heat can still be intense, especially in the early part of the month, there’s a noticeable shift as the weeks progress. The dog days of summer begin to wane, and the atmosphere starts its slow preparation for the more temperate and less humid conditions of the fall season. Overall, August remains a hot and humid month but with indications of the coming seasonal transition. It maintains a considerable chance of thunderstorms and precipitation but begins to pave the way for the pleasant conditions that September usually brings.
