Heat is on! When we normally see our 1st 90° day

Columbus (WCMH) – What a difference a week makes.  Last week we were pushing through a stretch of cooler weather with highs in the 50s to near 60°!  This week 70s, 80s, and possibly a sneaky 90°?

 

For the record… 90° is now the rule!

Starting May 14th through September 30th, the record high temperature for each and every day is at 90° or above.  Bottom line, if its in the upper 80s this time of year, we have done it before.

 

So when is our average 1st 90° day of the year?

Based on record keeping data since 1879 in Columbus, our average 1st 90° occurs on June 10th

  • Earliest:  April 25, 1915, 90°
  • Latest:  August 10, 1992, 91°
  • Average:  June 10th

 

Since 1879 to 2017, 90° typically occurs after the mid-point of May:

We have had 14 occurrences of 90° happening for the first time before May 15th.  That means in 125 years the first 90° happened on May 16th or later.

 

Below are the first dates for 90° in each year from 1879-2016:
