New Record Set for Most Days with Highs of 80 Degrees+

 

 

1944 ceded its #1 position to 2015 twice in regards to warm-temperature records.  First to fall was a streak of 80-degree+ days, which 2015 topped by three days (62 vs. 59); then a few weeks later 2015 once again passed 1944, this time to become the year with the most total days above 80°; by the end of September the number had risen to 114 vs. 1944's former top total of 108.

 

 

In a typical year nearly one-fourth of the days have highs in the 80s, but in 2015 one-third were 80°+.  However, the number of those days that were in the 90s was just slightly above average (20 vs. 17), ranking it 32nd among all years since 1900.  Among the ten years with the most 80°+ days (see chart below), 2015 had the fewest that were 90° or hotter.  As a result, the average temperature of 2015's days that were 80° or warmer was lower than all the other years (by one to three degrees). 

 

2015 set one more record pertaining to 80°+ days as every day in August had highs of 80°+.  Previous to this year the most 80° days in that month was 28.  This tied July 1944 as the only month to have every day in the 80s or warmer.  (And May 2015 set the record for most 80-degree days in May, with 18.)
