Louisville drivers will start the week in summerlike heat, but fall finally steps in by Wednesday as cooler air pushes south. Temperatures climb into the upper 80s through Tuesday before dropping back into the low 80s as October begins.
According to the National Weather Service in Louisville, calm mornings give way to light northeast breezes up to 7 mph by midweek. That means Interstate 65 and I-64 commuters can expect mostly clear drives, but vehicles may need extra caution for sun glare during rush hours.
Across central Kentucky, Monday and Tuesday remain hot for late September with highs around 88 to 86 degrees. Nights bring relief, with lows near 60, offering comfortable windows for outdoor events and energy savings. By Wednesday, high temperatures dip to 84, holding in the low 80s into the weekend, marking a steady shift toward fall.
Residents planning outdoor work or sports should stay hydrated early this week, as heat lingers longer than normal for late September. Farmers in Jefferson and Oldham counties will welcome the cooler stretch beginning Wednesday, which supports early October harvest activities.
Travelers on I-71 and local parkways should expect smooth conditions as skies stay dry. With no major storms in sight, utility crews anticipate minimal outages, giving Louisville residents a quiet start to October.
The long stretch of sunshine looks locked in. More updates will follow if any rain chances emerge next week, but for now, October begins on a calm note.
