August weather forecast
Kentucky, USA

August in Kentucky sustains the summer’s sweltering heat but begins to hint at the transition to fall. Daytime temperatures usually linger from 78°F (25.6°C) to 90°F (32.2°C), showing a slight decrease from July's peaks. Nighttime lows offer a small amount of cooling, ranging from 63°F (17.2°C) to 75°F (23.9°C).

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.

Relative to July, August presents a subtle decline in both heat and humidity. Nonetheless, the month remains one of the hottest and most humid on the annual calendar. Thunderstorms continue to punctuate the weather, although they are somewhat less frequent and severe compared to July.

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.
