CINCINNATI — The summer of 2023 could be considered a tame one so far. Through the first 80 days of the summer (June 1 through Aug. 19) we have only recorded six days of 90° or hotter.

By this point last year we had already seen 17. In fact, it is currently the 37th coolest summer on record in Cincinnati, dating back to 1872. That is 151 years of data.

Sunday made it only the seventh time this summer we have eclipsed 90° but that is just the start of it. Right now, it looks like we will make it above 90° every day through Friday.

When was the last time we had at least six days in a row of 90° or hotter? It was during the week of the Fourth of July in 2020. That stretch brought seven days in a row of 90° stretching from July 3 through July 9.

So you can say that this is the hottest week we will have seen in three years.

On top of that, Thursday’s forecast high temperature is for 96°. If that comes to fruition, it would be the first time we have hit 96° in Cincinnati since July 4, 2018. That is more than FIVE years ago! The last time we hit 97°? That's even longer. Try 11 years! That last happened on August 8, 2012.

Along with the heat will be the humidity, which is going to make it feel far worse all week long.

The peak heat index each day this week should be between 95° to 105°. This will likely lead to a Heat Advisory for most of these days. This should last through Friday and then we will get a break heading into next weekend.

Heat Safety Tips:

  • Wear light colored, loose fitting clothing
  • Take frequent breaks if working outdoors
  • Drink plenty of fluids, avoid alcohol
  • Keep shades/blinds closed and avoid using the oven

Also, this will be a good week to make sure you are checking in on your neighbors and the elderly. Don't forget about pets either! This dangerous heat can lead to heat illness for them as well.
Stay safe and stay cool!
