LOUISVILLE, Ky. — Summer officially starts Thursday at 4:51 p.m. and it will certainly feel like it in the Louisville area.

The WHAS11 First Alert StormTeam is forecasting a high temperature of 96 degrees in the Derby City, which is nine degrees above normal for June 20. A large portion of the country is in the middle of a heat wave bringing heat advisories and warnings across the Midwest and Northeast.

How does this compare to a normal first day of summer? Here are the high and low temperatures in Louisville for the last 10 years:

  • 2023: 85/71.
  • 2022: 90/62.
  • 2021: 91/74.
  • 2020: 92/71.
  • 2019: 79/69.
  • 2018: 90/76.
  • 2017: 88/69.
  • 2016: 89/76.

The average high temperature in Louisville for June 20 is 87. The record high is 100.

As warm as your thermometer will indicate Thursday, it will feel even hotter. Dew points will remain in the upper 60s for the next several days, and "feels like" temperatures will approach and possibly exceed 100.
