Louisville Dew Point Forecast — current conditions, comfort ratings, and 7-day outlook. Search any location →
Louisville anchors itself squarely in the demanding end of the Ohio Valley's summer climate. Dew points push into Uncomfortable and Oppressive territory (66–75°F) through July and August, and the river valley topography traps moisture effectively. The Kentucky Derby in early May typically lands in a transitional window — dew points are usually still in the Comfortable to Getting Sticky range, which is one of the reasons the event feels more bearable than later summer outdoor gatherings.
